   3.  Long-Term Debt
   On June 30, 1995, the Corporation's $140 million Revolver Agreement with a
   group of ten banks was amended to $160 million and the final maturity was
   extended from April 3, 1998 to June 30, 2000. The amended agreement also
   carries lower fees and lower borrowing rates.

   The Corporation's long-term credit agreements contain certain conditions
   and provisions which restrict the Corporation's payment of dividends. 
   Under the most restrictive of these provisions, retained earnings of $96.9
   million were unrestricted as of June 30, 1995 for cash dividends and
   treasury stock purchases.

   


   PART 1--FINANCIAL INFORMATION
   ITEM 2--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
          CONDITION AND RESULTS OF OPERATIONS

   Results of Operations - First six months of 1995 compared to 1994

   The slowdown in the domestic economy has not had a significant effect upon
   the corporation's businesses as evidenced by revenues and earnings for the
   first six months and second quarter of 1995 that surpassed those of any
   previous comparable period.  The corporation's ability to achieve this
   record performance despite indications of downturns in the automotive and
   electric motors markets is due largely to a concerted effort to gain
   market share and secure new customers.

   Revenues for the first half of 1995 were $792.8 million or almost 15
   percent better than the $690 million of revenues in the same period of
   1994.  Revenues of $399.8 million in the second quarter of 1995 surpassed
   last year's second quarter by $49.6 million or 14.2 percent.

   The corporation earned $38.4 million for the first half of 1995 compared
   to $33.7 million in the first half of 1994.  Second quarter earnings were
   $20 million in 1995, an increase of $2 million or more than 11 percent
   over the $18 million earned in the same quarter of 1994.

   The gross profit margin through the first half of the year was 16.2
   percent, identical to the margin for the same period last year.  The
   favorable impact of increased volume was offset by higher costs in most of
   the corporation's product operations and an unfavorable product mix.  In
   addition margins continued to be affected by costs associated with new
   product programs at the Automotive Products Company.  The second quarter
   gross margin of 16.1 percent declined from 16.7 percent from the second
   quarter of 1994 as the impact of higher material costs and lower margins
   on export shipments was evident.

   The Automotive Products Company sales in the first half of 1995 increased
   by 20 percent over the same period of 1994.  The second quarter of 1995
   exhibited a similar percentage increase over the same quarter of 1994. 
   These increases were in direct contrast to the three percent sales decline
   experienced by the domestic automotive industry during the first six
   months of the year.  Automotive's improved sales performance was
   influenced by a strong presence in the light truck segment, added volume
   resulting from new product programs completed in 1994 and early 1995, and
   continued strength in the heavy truck market.

   Automotive's 1995 earnings for the second quarter and first half were
   higher than comparable periods of 1994 despite absorbing the costs
   associated with new product programs introduced this year.

   The corporation's 40 percent owned Mexican affiliate experienced a good
   second quarter, and operations improved substantially over the prior year
   due to increased export shipments and a lower cost structure.  Due to the
   strengthening of the peso during the quarter, the corporation recognized a
   minimal translation gain, whereas in the first quarter of 1995, a
   translation loss was incurred.  The affiliate's results for the second
   quarter and first half of 1994 were impacted by start up costs for new
   products and costs incurred to realign manufacturing operations, the
   benefits of which are now being realized.

   Automotive will launch two significant product programs in the near
   future.  Engine cradles for the 1996 Ford Taurus/Mercury Sable will be
   shipped from the Granite City, Illinois plant while the Milwaukee,
   Wisconsin plant will start production of full frame assemblies for the
   extended cab version of the Dodge Ram pickup.  Also, during the second
   quarter Automotive announced it would be building two new plants. A plant
   near Roanoke, Virginia will supply customized frame rails for Class 8
   heavy trucks beginning in the third quarter of 1996, and a plant in
   Plymouth, Michigan will supply frames for the 1997 model year Dodge Dakota
   pick-up truck commencing in the summer of 1996.

   The labor contracts of the various unions at Automotive's Milwaukee plant
   expired on July 31, 1995. A ninety day no-strike extension has been agreed
   to by all the bargaining units represented and contract negotiations are
   currently underway.

   The Electrical Products Company followed its excellent first quarter of
   1995 with continued good performance in the second quarter.  Sales in the
   second quarter increased 13 percent over a very strong second quarter of
   1994.  Strength in the commercial hermetic market and increased export
   sales had a significant influence on second quarter volumes.  Year-to-date
   sales reflect almost a 17 percent increase over the first half of 1994 due
   to sustained high demand in all of the major markets the company serves.

   Electrical Products second quarter earnings were slightly less than last
   year's second quarter due primarily to increased cost of raw materials. 
   First half profits in 1995 were substantially higher than the same period
   in 1994 as a result of higher volume.

   The Water Products Company overcame its slow 1995 start with second
   quarter sales up 6.5 percent over last year's second quarter.  Increased
   commercial water heater volume contributed significantly to the improved
   second quarter performance as Water Products continues to gain share in
   this segment of the market.  The residential water heater market
   demonstrated a moderate recovery in the second quarter, however, the
   entire industry continues to trail last year's volumes.  Year-to-date
   sales were about equal to the first six months of 1994.

   Second quarter earnings for Water Products were 11.5 percent higher than
   the 1994 second quarter, reflecting increased volume and favorable product
   mix.  Profits for the first half of the year were equal to those for the
   first six months of 1994.

   Second quarter sales for Smith Fiberglass Products Inc. were lower than
   the second quarter of 1994 as this subsidiary continues to be affected by
   the industry wide slowdown in demand for service station pipe.  Sales for
   the first half of the year reflect a slight improvement over the same
   period last year as strong export sales helped offset lower petroleum
   marketing sales.

   Earnings for both the second quarter and first half of 1995 for Smith
   Fiberglass were lower than the comparable periods in 1994 as a result of
   lower margins associated with export sales, increased product development
   costs, and expenses related to global expansion activities.

   The corporation's agricultural operations reflected profits for both the
   second quarter and first half of the year in contrast to losses incurred
   in the same periods in 1994.  Through the first half of the year, revenues
   for A. O. Smith Harvestore Products, Inc. have increased nearly 21 percent
   over the first half of 1994 as the result of strong demand for a new
   unloader product and an improving market for municipal/industrial and
   water and waste storage products.  The significant increase in sales
   resulted in a substantial improvement in earnings for both the second
   quarter and first half of 1995.  The losses incurred by AgriStor Credit
   Corporation were lower in 1995 than 1994 due to lower operating expenses
   and lower debt service costs as this finance subsidiary continues to be
   liquidated.

   Selling, general and administrative expenses for the second quarter and
   first half increased $3.3 million and $6.7 million respectively, over the
   comparable periods in 1994, but remained relatively constant as a
   percentage of sales.  The absolute increase was associated with higher
   employee incentives due to increased earnings in certain units and general
   increases to support the higher sales volumes.  Despite reduced debt
   levels, interest expense for the first half of the year was 8.4 percent
   higher than the first half of 1994 due to higher interest rates.

   Other expenses were relatively consistent for the second quarters of 1995
   and 1994, however the first half of 1995 reflects a $2.0 million increase
   over the same period in 1994.  This increase is explained by translation
   losses, environmental costs and certain non-recurring costs incurred in
   1995.  The effective tax rates for the second quarter and first half of
   1995 were slightly less than the same periods in 1994 due to the
   recognition of additional research and development tax credits in 1995.

   During the first six months of 1995, the corporation was a party to
   futures contracts for purposes of hedging a portion of certain raw
   material purchases.  The corporation was also a party to forward foreign
   exchange contracts to hedge foreign currency transactions consistent with
   its committed exposures.  Had these contracts not been in place, the net
   earnings of the corporation would not have been materially affected in the
   second quarter or first half of 1995.

   On the strength of a solid financial performance for the first half of
   1995, and assuming no major economic downturn, the corporation remains
   optimistic about its ability to provide a third consecutive year of record
   profits for its shareholders.


   Liquidity and Capital Resources

   The Corporation's working capital was $130.8 million at June 30, 1995
   compared to $113.6 million at December 31, 1995. Sales related increases
   in trade receivables were partially offset by a decrease in customer
   tooling.  

   Cash flow provided by operations was $7.0 million greater than the same
   period last year due primarily to higher earnings.  The Corporation's
   long-term debt increased $1.2 million in the first six months to $138.0
   million due to slightly higher capital expenditures. The long-term debt of
   the finance subsidiary declined $4.2 million to $25.1 million reflecting
   the continuing liquidation of that business.

   In June, the Corporation amended its revolving credit agreement. The
   facility was increased from $140 million to $160 million, and the term of
   the agreement was extended two years to June 30, 2000. The amended
   agreement also carries lower fees and lower borrowing rates.

   Due primarily to the recently announced automotive unit manufacturing
   plants in Roanoke, Virginia, and Plymouth, Michigan, the corporation
   expects its 1995 capital expenditures to exceed $100 million versus the
   corporation's original forecast of $80 million. The corporation
   anticipates that internally generated funds will cover capital expenditure
   requirements for the remainder of the year and that year-end debt levels
   will not vary significantly from current levels.

   At its June 6, 1995 meeting, A. O. Smith's Board of Directors declared a
   regular quarterly dividend of $.15 per share on its common stock (Classes
   A and Common).  The dividend is payable on August 15, 1995 to shareholders
   of record as of July 31, 1995.

   
   PART II -- OTHER INFORMATION
   ITEM 1 -- LEGAL PROCEEDINGS


   At June 30, 1995, the Corporation or A. O. Smith Harvestore Products, Inc.
   ("AOSHPI"), a wholly-owned subsidiary of the Corporation, were defendants
   in approximately nine (9) lawsuits (two of which are class action
   lawsuits) filed by various plaintiffs who were alleging property damage
   claimed to have arisen out of alleged defects in AOSHPI's animal feed
   storage equipment.  In the second quarter of 1995, no new cases were filed
   against the Corporation and AOSHPI and six cases were favorably resolved. 
   The United States District Court for the Southern District of Ohio has set
   a trial date in the conditionally certified class action brought on behalf
   of purchasers and lessees of Harvestore structures manufactured by the
   Corporation and AOSHPI.  Discovery in the case is ongoing and a trial of
   the liability issues only is scheduled to begin on October 16, 1995. 
   Damages would be tried at a later date and only after a liability finding. 
   Information on these lawsuits was previously reported in Part I, Item 3 of
   the Corporation's annual report on Form 10-K for the fiscal year ended
   December 31, 1994 and in Part II, Item 1 of the Corporation's Form 10-Q
   report for the quarterly period ended March 31, 1995, which are
   incorporated herein by reference.

   There have been no material changes in the environmental matters
   previously reported in Item 3 in the Corporation's annual report on Form
   10-K for the fiscal year ended December 31, 1994, which is incorporated
   herein by reference.


   ITEM 2--CHANGES IN SECURITIES

   On June 30, 1995, the Corporation's $140,000,000 Revolver Agreement with a
   group of ten banks was amended to $160,000,000 and the final maturity was
   extended from April 3, 1998 to June 30, 2000.  The covenants and
   restrictions on the payment of dividends remain essentially the same. 
   Refer to Note 3 on page 7 of this report for more detailed information
   regarding the Corporation's debt covenants, dividend payment restrictions
   and retained earnings.


   ITEM 4 -- SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

   On March 1, 1995, the Corporation mailed a proxy statement to its
   stockholders relating to the annual meeting of stockholders on April 5,
   1995.  The annual meeting included the election of directors and the
   consideration and action upon proposals to amend the Restated Certificate
   of Incorporation to increase the number of authorized shares of Class A
   Common Stock from 7,000,000 to 14,000,000 shares and the number of
   authorized shares of Common Stock from 24,000,000 to 60,000,000 shares, to
   approve the ratification of Ernst and Young LLP as the independent
   auditors of the Corporation for 1995 and to act upon a stockholder
   proposal relating to the rotation of the annual meeting of stockholders.

   Directors are elected by a plurality of the votes cast, by proxy or in
   person, with the holders voting as separate classes.  A plurality of votes
   means that the nominees who receive the greatest number of votes cast are
   elected as directors.  Consequently, any shares which are not voted,
   whether by abstention, broker nonvotes or otherwise, will have no effect
   on the election of directors.

   With respect to the Company's proposal to amend the Restated Certificate
   of Incorporation, the affirmative vote of the holders of a majority of the
   outstanding shares of the Class A Common Stock and the Common Stock
   entitled to vote at the meeting, each voting as a separate class, is
   needed for adoption of the proposed amendment.  In addition, the proposal
   must be adopted by the vote of the Class A Common Stock and the Common
   Stock voting together as a single class in the manner described in the
   paragraph below.

   For all other matters considered at the meeting, both classes of stock
   vote together as a single class, with the Class A Common Stock entitled to
   one vote per share and the Common Stock entitled to 1/10th vote per share. 
   All such other matters are decided by a majority of the votes cast.  On
   such other matters, an abstention will have the same effect as a "no" vote
   but, because shares held by brokers will not be considered to vote on
   matters as to which the brokers withhold authority, a broker nonvote will
   have no effect on the vote.

        conditions of this Agreement, the Borrower may borrow CAF
        Advances from time to time on any Euro-Dollar Business Day in
        the case of London Interbank Offered Rate CAF Advances or any
        Domestic Business Day in the case of any Fixed Rate CAF Advances
        during the CAF Advance Availability Period.  CAF Advances shall
        be borrowed in amounts such that the aggregate amount of Loans
        outstanding at any time shall not exceed the aggregate amount of
        the Commitments at such time.  Within the limits and on the
        conditions hereinafter set forth with respect to CAF Advances,
        the Borrower from time to time may borrow, repay and reborrow
        CAF Advances.

             Section 2.14  Procedure for CAF Advance Borrowing. 
        (a) The Borrower shall request CAF Advances by delivering a CAF
        Advance Request to the Agent, not later than 12:00 Noon (New
        York City time) four Euro-Dollar Business Days prior to the
        proposed Borrowing Date (in the case of a London Interbank
        Offered Rate CAF Advance Request), and not later than 10:00 A.M.
        (New York City time) one Domestic Business Day prior to the
        proposed Borrowing Date (in the case of a Fixed Rate CAF Advance
        Request).  Each CAF Advance Request may solicit bids for CAF
        Advances in an aggregate principal amount of $10,000,000 or an
        integral multiple of $1,000,000 in excess thereof and having not
        more than three alternative CAF Advance Maturity Dates.  The CAF
        Advance Maturity Date for each CAF Advance shall be the date set
        forth therefor in the relevant CAF Advance Request, which date
        shall be (i) not less than 7 days nor more than 180 days after
        the Borrowing Date therefor, in the case of a Fixed Rate CAF
        Advance, (ii) one, two, three or six months after the Borrowing
        Date therefor, in the case of a London Interbank Offered Rate
        CAF Advance and (iii) not later than the Termination Date, in
        the case of any CAF Advance.  The Agent shall notify each Bank
        promptly by telecopy of the contents of each CAF Advance Request
        received by the Agent. 

             (b)  In the case of a London Interbank Offered Rate CAF
        Advance Request, upon receipt of notice from the Agent of the
        contents of such CAF Advance Request, each Bank may elect, in
        its sole discretion, to offer irrevocably to make one or more
        CAF Advances at the applicable London Interbank Offered Rate
        plus (or minus) a margin determined by such Bank in its sole
        discretion for each such CAF Advance.  Any such irrevocable
        offer shall be made by delivering a CAF Advance Offer to the
        Agent, before 10:30 A.M. (New York City time) on the day that is
        three Euro-Dollar Business Days before the proposed Borrowing
        Date, setting forth:

                  (i)  the maximum amount of CAF Advances for each CAF
             Advance Maturity Date (which amount shall be at least
             $5,000,000) and the aggregate maximum amount of CAF Advances for
             all CAF Advance Maturity Dates which such Bank would be willing
             to make (which amounts may, subject to Section 2.13, exceed such
             Bank's Commitment); and

                 (ii)  the margin above or below the applicable London
             Interbank Offered Rate at which such Bank is willing to make
             each such CAF Advance.

        The Agent shall advise the Borrower before 11:00 A.M. (New York City
        time) on the date which is three Euro-Dollar Business Days before the
        proposed Borrowing Date of the contents of each such CAF Advance
        Offer received by it.  If the Agent, in its capacity as a Bank, shall
        elect, in its sole discretion, to make any such CAF Advance Offer, it
        shall advise the Borrower of the contents of its CAF Advance Offer
        before 10:15 A.M. (New York City time) on the date which is three
        Euro-Dollar Business Days before the proposed Borrowing Date.

             (c)  In the case of a Fixed Rate CAF Advance Request, upon
        receipt of notice from the Agent of the contents of such CAF
        Advance Request, each Bank may elect, in its sole discretion, to
        offer irrevocably to make one or more CAF Advances at a rate of
        interest determined by such Bank in its sole discretion for each
        such CAF Advance.  Any such irrevocable offer shall be made by
        delivering a CAF Advance Offer to the Agent before 9:30 A.M.
        (New York City time) on the proposed Borrowing Date, setting
        forth:

                  (i)  the maximum amount of CAF Advances for each CAF
             Advance Maturity Date (which amount shall be at least
             $5,000,000) and the aggregate maximum amount for all CAF Advance
             Maturity Dates, which such Bank would be willing to make (which
             amounts may, subject to Section 2.13, exceed such Bank's
             Commitment); and

                 (ii)  the rate of interest at which such Bank is willing to
             make each such CAF Advance.

        The Agent shall advise the Borrower before 10:00 A.M. (New York City
        time) on the proposed Borrowing Date of the contents of each such CAF
        Advance Offer received by it.  If the Agent, in its capacity as a
        Bank, shall elect, in its sole discretion, to make any such CAF
        Advance Offer, it shall advise the Borrower of the contents of its
        CAF Advance Offer before 9:15 A.M. (New York City time) on the
        proposed Borrowing Date.

             (d)  Before 11:30 A.M. (New York City time) three Euro-
        Dollar Business Days before the proposed Borrowing Date (in the
        case of CAF Advances requested by a London Interbank Offered
        Rate CAF Advance Request) and before 10:30 A.M. (New York City
        time) on the proposed Borrowing Date (in the case of CAF
        Advances requested by a Fixed Rate CAF Advance Request), the
        Borrower, in its absolute discretion, shall:

                  (i)  cancel such CAF Advance Request by giving the Agent
             telephone notice followed by confirmation by telecopy to that
             effect, or

                 (ii)  by giving telephone notice to the Agent (immediately
             confirmed by delivery to the Agent of a CAF Advance Confirmation
             by telecopy) (A) subject to the provisions of Section 2.14(e),
             accept one or more of the offers made by any Bank or Banks
             pursuant to Section 2.14(b) or Section 2.14(c), as the case may
             be, and (B) reject any remaining offers made by Banks pursuant
             to Section 2.14(b) or Section 2.14(c), as the case may be.

             (e)  The Borrower's acceptance of CAF Advances in response
        to any CAF Advance Request shall be subject to the following
        limitations:

                  (i)  the amount of CAF Advances accepted for each CAF
             Advance Maturity Date specified by any Bank in its CAF Advance
             Offer shall not exceed the maximum amount for such CAF Advance
             Maturity Date specified in such CAF Advance Offer;

                 (ii)  the aggregate amount of CAF Advances accepted for all
             CAF Advance Maturity Dates specified by any Bank in its CAF
             Advance Offer shall not exceed the aggregate maximum amount
             specified in such CAF Advance Offer for all such CAF Advance
             Maturity Dates;

                (iii)  the Borrower may not accept offers for CAF Advances
             for any CAF Advance Maturity Date in an aggregate principal
             amount in excess of the maximum principal amount requested in
             the related CAF Advance Request; and 

                 (iv)  if the Borrower accepts any of such offers, it must
             accept offers based solely upon pricing for each relevant CAF
             Advance Maturity Date and upon no other criteria whatsoever and
             if two or more Banks submit offers for any CAF Advance Maturity
             Date at identical pricing and the Borrower accepts any of such
             offers but does not wish to (or by reason of the limitations set
             forth in Section 2.13, cannot) borrow the total amount offered
             by such Banks with such identical pricing, the Borrower shall
             accept offers from all of such Banks in amounts allocated among
             them pro rata according to the amounts offered by such Banks;
             provided that if the number of Banks that submit offers for any
             CAF Advance Maturity Date at identical pricing is such that,
             after the Borrower accepts such offers pro rata in accordance
             with the foregoing, the CAF Advance to be made by such Banks
             would be less than $5,000,000 principal amount, the number of
             such Banks shall be reduced by the Agent by lot until the CAF
             Advances to be made by such remaining Banks would be in a
             principal amount of $5,000,000 or an integral multiple of
             $1,000,000 in excess thereof).

             (f)  If the Borrower notifies the Agent that a CAF Advance
        Request is cancelled pursuant to Section 2.14(d)(i), the Agent
        shall give prompt telephone notice thereof to the Banks.

             (g)  If the Borrower accepts pursuant to Section
        2.14(d)(ii) one or more of the offers made by any Bank or Banks,
        the Agent promptly shall notify each Bank which has made such an
        offer of (i) the aggregate amount of such CAF Advances to be
        made on such Borrowing Date for each CAF Advance Maturity Date
        and (ii) the acceptance or rejection of any offers to make such
        CAF Advances made by such Bank.  Before 12:00 Noon (New York
        City time) on the Borrowing Date specified in the applicable CAF
        Advance Request, each Bank whose CAF Advance Offer has been
        accepted shall make available to the Agent at its office set
        forth in Section 9.1 the amount of CAF Advances to be made by
        such Bank, in immediately available funds.  The Agent will make
        such funds available to the Borrower as soon as practicable on
        such date at such office of the Agent.  As soon as practicable
        after each Borrowing Date, the Agent shall notify each Bank of
        the aggregate amount of CAF Advances advanced on such Borrowing
        Date and the respective CAF Advance Maturity Dates thereof.

             Section 2.15  CAF Advance Payments.  (a)  The Borrower
        shall pay to the Agent for the account of each Bank which has
        made a CAF Advance on the applicable CAF Advance Maturity Date
        the then unpaid principal amount of such CAF Advance.  The
        Borrower shall not have the right to prepay any principal amount
        of any CAF Advance without the consent of the Bank to which such
        CAF Advance is owed.

             (b)  The Borrower shall pay interest on the unpaid
        principal amount of each CAF Advance from the Borrowing Date to
        the applicable CAF Advance Maturity Date at the rate of interest
        specified in the CAF Advance Offer accepted by the Borrower in
        connection with such CAF Advance (calculated on the basis of a
        360-day year for actual days elapsed), payable on each
        applicable CAF Advance Interest Payment Date.

             (c)  If all or a portion of the principal amount of any CAF
        Advance shall not be paid when due (whether at the stated
        maturity, by acceleration or otherwise), such overdue principal
        amount shall, without limiting any rights of any Bank under this
        Agreement, bear interest from the date on which such payment was
        due at a rate per annum which is 1% above the rate which would
        otherwise be applicable pursuant to the CAF Advance Note
        evidencing such CAF Advance until the stated CAF Advance
        Maturity Date of such CAF Advance, and for each day thereafter
        at a rate per annum which is 1% above the Alternate Base Rate,
        in each case until paid in full (as well after as before
        judgment).  Interest accruing pursuant to this paragraph (c)
        shall be payable from time to time on demand.

             Section 2.16  CAF Advance Notes.  The CAF Advances made by
        each Bank shall be evidenced by a promissory note of the
        Borrower, substantially in the form of Exhibit B with
        appropriate insertions (a "CAF Advance Note"), payable to the
        order of such Bank and representing the obligation of the
        Borrower to pay the unpaid principal amount of all CAF Advances
        made by such Bank, with interest on the unpaid principal amount
        from time to time outstanding of each CAF Advance evidenced
        thereby as prescribed in subsection 2.15(b).  Each Bank is
        hereby authorized to record the date and amount of each CAF
        Advance made by such Bank, the CAF Advance Maturity Date
        thereof, the date and amount of each payment of principal
        thereof and the interest rate with respect thereto on the
        schedule attached to and constituting part of its CAF Advance
        Note, and any such recordation shall constitute prima facie
        evidence of the accuracy of the information so recorded;
        provided, however, that the failure to make any such recordation
        shall not affect the obligations of the Borrower hereunder or
        under any CAF Advance Note.  Each CAF Advance Note shall be
        dated the Third Amendment Effective Date and each CAF Advance
        evidenced thereby shall bear interest for the period from and
        including the Borrowing Date of such CAF Advance on the unpaid
        principal amount thereof from time to time outstanding at the
        applicable rate per annum determined as provided in, and such
        interest shall be payable as specified in, Section 2.15(b).

             Section 2.17  Certain Restrictions.  A CAF Advance Request
        may request offers for CAF Advances to be made on not more than
        one Borrowing Date and to mature on not more than three CAF
        Advance Maturity Dates.  No CAF Advance Request may be submitted
        earlier than five Domestic Business Days after submission of any
        other CAF Advance Request.

             4.  Amendment of Article III of the Credit Agreement.  Section
   3.1(d) of the Credit Agreement is hereby amended by deleting said Section
   in its entirety and substituting in lieu thereof the following:

             "(d) the fact that since December 31, 1994 there shall not have
        been any change in the business or financial position of the Borrower
        or any of its Consolidated Subsidiaries, which in the opinion of
        Banks holding at least 50% of the aggregate amount of the
        Commitments, is materially adverse to the business or financial
        position of the Borrower and its Consolidated Subsidiaries considered
        as a whole."

             5.  Amendment of Article IV of the Credit Agreement.  Sections
   4.4(a) and 4.4(b) of the Credit Agreement are hereby amended by deleting
   said Sections in their entirety and substituting in lieu thereof the
   following:

             "(a) The consolidated balance sheet of the Borrower and its
        Consolidated Subsidiaries as of December 31, 1994 and the
        related consolidated statements of operations and retained
        earnings and changes in financial position for the fiscal year
        then ended, reported on by Ernst & Young and set forth in the
        Borrower's 1994 Form 10-K, a copy of which has been delivered to
        each of the Banks, fairly present, in conformity with generally
        accepted accounting principles, the consolidated financial
        position of the Borrower and its Consolidated Subsidiaries as of
        such date and their consolidated results of operations and
        changes in financial position for such fiscal year.

             (b)  Since December 31, 1994 there have been no material adverse
        change in the business, financial position or results of operations
        of the Borrower and its Consolidated Subsidiaries, considered as a
        whole."

             6.  Amendment of Schedule I of the Credit Agreement.  The Credit
   Agreement is hereby further amended by deleting Schedule I in its entirety
   and inserting in lieu thereof Schedule I attached hereto.

             7.  Representations and Warranties of Borrower.  The Borrower
   hereby represents and warrants that each of the representations and
   warranties of the Borrower contained in the Credit Agreement, as amended
   by this Amendment, is true and correct on the date hereof as if made on
   and as of the date hereof except that representations and warranties that
   apply to a specific date were true and correct as of such date.

             8.  Effectiveness.  This Third Amendment shall become effective
   as of the first date (the "Third Amendment Effective Date") prior to June
   30, 1995 or the first day thereafter when the following conditions shall
   have been met:

         (i)      the Agent shall have received counterparts 
                  hereof, duly executed by the Borrower and all the Banks;

        (ii)      the Agent shall have received an opinion of W. 
                  David Romoser, General Counsel of the Borrower to be
                  attached as Exhibit A.

        (iii)     the Agent shall have received a copy of the resolutions, in
                  form and substance satisfactory to the Agent, of the Board
                  of Directors of the Borrower authorizing the execution and
                  delivery of this Amendment, certified by the Secretary or
                  an Assistant Secretary of the Borrower, as the case may be,
                  as of the Third Amendment Effective Date, which certificate
                  shall state that the resolutions thereby certified have not
                  been amended, modified, revoked or rescinded since the date
                  of adoption thereof.

             9.  Continuing Effect of Credit Agreement.  This Amendment shall
   not constitute a waiver or amendment of any other provision of the Credit
   Agreement not expressly referred to herein and shall not be construed as a
   waiver or consent to any further or future action on the part of the
   Borrower that would require a waiver or consent of the Required Banks or
   the Agent.  Except as expressly amended hereby, the provisions of the
   Credit Agreement are and shall remain in full force and effect.

             10.  Counterparts.  This Amendment may be executed by the
   parties hereto in any number of counterparts, and all of such counterparts
   taken together shall be deemed to constitute one and the same instrument.

             11.  GOVERNING LAW.  THIS AMENDMENT SHALL BE GOVERNED BY, AND
   CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
   YORK.

             IN WITNESS WHEREOF, the parties hereto have caused this
   Amendment to be duly executed and delivered in New York, New York by their
   proper and duly authorized officers as of the day and year first above
   written.

                                                                June 30, 1995


   To the Banks and the Agent
     Referred to Below
   c/o Chemical Bank,
     as Agent
   270 Park Avenue
   New York, New York  10017

   Dear Sirs:

             I have acted as counsel for A.O. Smith Corporation (the
   "Borrower") in connection with the Extension and Third Amendment, dated as
   of June 30, 1995 (the "Third Amendment"), to the Amended and Restated
   Credit Agreement (the "Credit Agreement") dated as of February 26, 1993
   among the Borrower, the banks listed on the signature pages thereof and
   Chemical Bank, as Agent.  Terms defined in the Credit Agreement are used
   herein as therein defined.

             I have examined originals or copies, certified or otherwise
   identified to my satisfaction, of such documents, corporate records,
   certificates of public officials and other instruments and have conducted
   such other investigations of fact and law as I have deemed necessary or
   advisable for purposes of this opinion.

             Upon the basis of the foregoing, I am of the opinion that:

             1.  The Borrower is a corporation duly incorporated, validly
   existing and in good standing under the laws of Delaware, and has all
   corporate powers and all material governmental licenses, authorizations,
   consents and approvals required to carry on its business as now conducted.

             2.  The execution, delivery and performance by the Borrower of
   the Third Amendment are within the Borrower's corporate powers, have been
   duly authorized by all necessary corporate action, require no action by or
   in respect of, or filing with, any governmental body, agency or official
   and does not contravene, or constitute a default under, any certificate of
   incorporation or by-laws of the Borrower or, to the best of my knowledge,
   of any agreement, judgment, injunction, order, decree or other instrument
   binding upon the Borrower or result in the creation or imposition of any
   Lien on any asset of the Borrower or any of its Subsidiaries.

             3.  The execution, delivery and performance by the Borrower the
   Notes are within the Borrower's corporate powers, have been duly
   authorized by all necessary corporate action, require no action by or in
   respect of, or filing with, any governmental body, agency or official and
   does not contravene, or constitute a default under, any certificate of
   incorporation or by-laws of the Borrower or, to the best of my knowledge,
   of any agreement, judgment, injunction, order, decree or other instrument
   binding upon the Borrower or result in the creation or imposition of any
   Lien on any asset of the Borrower or any of its Subsidiaries.

             4.  The Third Amendment and the New Notes constitute the valid
   and the binding obligations of the Borrower enforceable in accordance with
   their terms, except as enforceability may be limited by applicable
   bankruptcy, insolvency, reorganization, moratorium or similar laws
   affecting the enforcement of creditors' rights generally and by general
   equitable principles.

             5.  Except as set forth in the Ilhardt, et al. v. A.O. Smith
   Corp., et al. lawsuit, there is no action, suit or proceeding pending
   against, or to the best of my knowledge threatened against or affecting,
   the Borrower or any of its Subsidiaries before any court or arbitrator or
   any governmental body, agency or official, in which there is a reasonable
   possibility of an adverse decision which could materially adversely affect
   the business, consolidated financial position or consolidated results of
   operations of the Borrower and its Consolidated Subsidiaries, considered
   as a whole or which in any manner draws into question the validity of the
   Third Amendment.

             6.  Each of the Borrower's Subsidiaries is a corporation validly
   existing and in good standing under the laws of its jurisdiction of
   incorporation, and has all corporate powers and all material governmental
   licenses, authorizations, consents and approvals required to carry on its
   business as now conducted.

                                      Very truly yours,

   
                                                                    Exhibit B

                                     FORM OF
                                CAF ADVANCE NOTE


                                                New York, New York
                                                [Date]


        FOR VALUE RECEIVED, the undersigned, A.O. Smith Corporation, a
   Delaware corporation (the "Borrower"), hereby unconditionally promises to
   pay to the order of                                   (the "Bank") at the
   office of Chemical Bank located at 270 Park Avenue, New York, New York
   10017, in lawful money of the United States of America and in immediately
   available funds, the aggregate unpaid principal amount of each CAF Advance
   which is made by the Bank to the Borrower pursuant to subsection 2.13 of
   the Credit Agreement, as hereinafter defined.  The principal amount of
   each CAF Advance evidenced hereby shall be payable on the CAF Advance
   Maturity Date therefor set forth on the schedule attached hereto and made
   a part hereof or on a continuation of such schedule which shall be
   attached hereto and made a part hereof (the "Grid").  The Borrower further
   agrees to pay interest in like money at such office on the unpaid
   principal amount of each CAF Advance evidenced hereby, at the rate per
   annum set forth in respect of such CAF Advance on the Grid, calculated on
   the basis of a year of 360 days and actual days elapsed from the Borrowing
   Date of such CAF Advance until the due date thereof (whether at the stated
   maturity, by acceleration or otherwise) and thereafter at the rates
   determined in accordance with subsection 2.15(c) of the Credit Agreement. 
   Interest on each CAF Advance evidenced hereby shall be payable on the date
   or dates set forth in respect of such CAF Advance on the Grid.  CAF
   Advances evidenced by this Note may not be prepaid without the consent of
   the Bank.

        The holder of this Note is authorized to endorse on the Grid the
   Borrowing Date, amount, Interest rate, Interest Payment Dates and CAF
   Advance Maturity Date in respect of each CAF Advance made pursuant to
   subsection 2.13 of the Credit Agreement and each payment of principal with
   respect thereto.  Each such endorsement shall constitute prima facie
   evidence of the accuracy of the information endorsed.  The failure to make
   any such endorsement shall not affect the obligations of the Borrower in
   respect of such CAF Advance.

        This Note is one of the CAF Advance Notes referred to in the Amended
   and Restated Credit Agreement dated as of February 26, 1993 (as amended,
   supplemented or otherwise modified from time to time, the "Credit
   Agreement"), among the Borrower, the Bank, the other banks and financial
   institutions from time to time parties thereto and Chemical Bank, as Agent
   and is subject to the provisions of the Credit Agreement.

        Upon the occurrence of any one or more of the Events of Default, all
   amounts then remaining unpaid on this Note shall become, or may be
   declared to be, immediately due and payable, all as provided in the Credit
   Agreement.

        All parties now and hereafter liable with respect to this Note,
   whether maker, principal, surety, guarantor, endorser or otherwise, hereby
   waive presentment, demand, protest and all other notices of any kind.

        Unless otherwise defined herein, terms defined in the Credit
   Agreement and used herein shall have the meanings given to them in the
   Credit Agreement.

        THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
   ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.
