1. Unaudited Consolidated Financial Statements

   The consolidated balance sheet as of March 31, 2003, the
   consolidated statements of operations for the three months ended
   March 31, 2003 and 2002 and the condensed consolidated
   statements of cash flows for the three months ended March 31,
   2003 and 2002 have been prepared by Ampco-Pittsburgh Corporation
   (the Corporation) without audit. In the opinion of management,
   all adjustments, consisting of only normal recurring
   adjustments, necessary to present fairly the financial position,
   results of operations and cash flows for the periods presented
   have been made.

   Certain information and footnote disclosures normally included
   in financial statements prepared in accordance with generally
   accepted accounting principles have been condensed or omitted.
   These consolidated financial statements should be read in
   conjunction with the consolidated financial statements and notes
   thereto incorporated by reference in the Corporation's annual
   report to shareholders on Form 10-K for the year ended December
   31, 2002.  The results of operations for the three months ended
   March 31, 2003 are not necessarily indicative of the operating
   results expected for the full year.

2. Restructuring

   In the third quarter of 2002, the Corporation made permanent
   reductions in manning levels at several of its operations and
   initiated the closure of its leased Plastics Processing
   Machinery facility in South Carolina.  An initial restructuring
   provision of $1,337,000 for costs associated with these efforts
   was recorded and as of December 31, 2002, approximately $167,000
   remained outstanding.  Restructuring activity for 2003 was as
   follows:

                                          (in thousands)
                                   December 31,        March 31,

                                    $   167  $   (66)  $  101

   The restructuring reserve as of March 31, 2003 represents

   quarter of 2003 and costs associated with the closure of the
   leased facility such as lease payments and holding costs through

   currencies.  To minimize this risk, forward foreign exchange
   contracts

                               - 7 -

   are purchased which are designated as fair value hedges or,
   beginning in 2002, cash flow hedges.  As of March 31, 2003,
   approximately $15,639,000 of anticipated foreign denominated
   sales have been hedged with the underlying contracts settling at
   various dates beginning in 2003 through 2005.  As of March 31,
   2003, the fair value of contracts expected to settle within the
   next 12 months, which is recorded in other current liabilities,
   approximated $1,761,000 and the fair value of the remaining
   contracts, which is recorded in other noncurrent liabilities,
   approximated $355,000.  The change in the fair value of the
   contracts designated as cash flow hedges is recorded as a
   component of other comprehensive loss and approximated $641,000,
   net of taxes, as of March 31, 2003.  The change in fair value
   will be reclassified into earnings when the projected sales
   occur with approximately $582,000, net of taxes, expected to be
   released to earnings within the next 12 months.

   Gains (losses) on foreign exchange transactions approximated
   $(163,000) and $(197,000) for the three months ended March 31,
   2003 and 2002 respectively.

   In addition, one of the Corporation's subsidiaries is subject to
   risk from increases in the price of a commodity used in the
   production of inventory.  To minimize this risk, futures
   contracts are entered into which are designated as cash flow
   hedges.  At March 31, 2003, approximately 100% or $2,024,000 of
   anticipated commodity purchases over the next 15 months are
   hedged.  The fair value of the contracts expected to be settled
   within the next 12 months approximated $37,000 and the fair
   value of the remaining contracts approximated $23,000 as of
   March 31, 2003.  The change in the fair value of the contracts
   designated as cash flow hedges is recorded as a component of
   other comprehensive loss and approximated $36,000, net of taxes,
   as of March 31, 2003.  The change in the fair value will be
   reclassified into earnings when the projected sales occur with
   approximately $22,000, net of taxes, expected to be released to
   earnings within the next 12 months.

8. Earnings Per Share

   Basic earnings per share are computed by dividing net income
   before cumulative effect of change in accounting for goodwill,
   cumulative effect of change in accounting for goodwill, and net
   income (loss) by the weighted average number of common shares
   outstanding for the period.  The weighted average number of
   common shares outstanding for the three months ended March 31,
   2003 and 2002 equaled 9,632,497 and 9,608,897 shares,
   respectively.

   The computation of diluted earnings per share is similar to
   basic earnings per share except that the denominator is
   increased to include the dilutive effect of the net additional
   common shares that would have been outstanding assuming exercise
   of outstanding stock options, calculated using the treasury
   stock method.  The weighted average number of common shares
   outstanding assuming exercise of the stock options was 9,688,242
   and 9,629,366 shares for the three months ended March 31, 2003
   and 2002, respectively.

9. Business Segments

   Presented below are the net sales and income (loss) before taxes
   for the Corporation's three business segments.  In the fourth
   quarter 2002, the Corporation began evaluating the performance
   of its segments based solely on income from operations without
   an allocation of corporate expenses to give it the ability to
   focus on actual operating performance for each of the segments.
   Prior year information has been restated to conform to the 2003
   presentation.

10. Investment in Joint Venture

   Effective January 2003, the U.K. cast roll operation entered
   into an agreement to sell technical know-how to a newly created
   joint venture in China.  In addition to cash proceeds, the U.K.
   operations received an interest in the joint venture, the value
   of which is not material.

11. Litigation and Environmental Matters

   The Corporation and its subsidiaries are involved in various
   claims and lawsuits incidental to their businesses. In
   addition, claims have been asserted alleging personal injury
   from exposure to asbestos-containing components historically
   used in some products of certain of the Corporation's
   subsidiaries. As of March 31, 2003, those subsidiaries, and in
   some cases, the Corporation, were defendants (among a number of
   defendants, typically over 50 and often over 100) in cases
   filed in various state and federal courts involving
   approximately 18,500 claimants. Most of the claims were made in
   a small number of lawsuits filed in Mississippi in 2002 and
   2003. The filings do not typically identify specific products
   as a source of asbestos exposure. The Corporation's aggregate
   gross settlement costs, including defense costs, in the first
   quarter of 2003 were approximately $350,000, substantially all
   of which was paid by insurance. Fourteen cases, each involving
   a single claimant, have been dismissed in the first quarter of
   2003 without any payment.

                               - 9 -

   On February 7, 2003, Utica Mutual Insurance Company ("Utica")
   filed a lawsuit in the Supreme Court of the State of New York,
   County of Oneida against the Corporation and certain of the
   subsidiaries named in the underlying asbestos actions (the
   "Policyholder Defendants") and three other insurance carriers
   that provided primary coverage to the Corporation (the "Insurer
   Defendants"). In the lawsuit, Utica has alleged (i) it has no
   coverage obligation for years where the Policyholder Defendants
   cannot establish the existence of insurance contracts or
   coverage, where exposure occurred outside of the Utica policy
   periods or with respect to allegedly excluded products; (ii)
   the Policyholder Defendants breached the insurance contracts;
   and (iii) the Insurer Defendants have defense and indemnity
   obligations under insurance contracts they have issued to the
   Policyholder Defendants. Utica is seeking a declaratory
   judgment from the court on these issues and recoupment of
   amounts it has already paid. The Corporation and its
   subsidiaries named in the lawsuit have answered Utica's
   complaint, denying that Utica is entitled to the relief it
   requests against them, and have also asserted counterclaims
   against Utica. Although the outcome of this action cannot be
   predicted with certainty, the Corporation believes that the
   lawsuit ultimately should benefit all parties by defining the
   obligations of Utica and the Insurer Defendants to the
   Corporation and that the majority of the defense and indemnity
   costs of the pending cases ultimately will be covered by the
   appropriate insurance policies.

   Based on the Corporation's claims experience to date, insurance
   coverage and the identity of the subsidiaries that are named in
   the cases, the Corporation believes that the pending legal
   proceedings will not have a material adverse effect on its
   consolidated financial condition or liquidity. The outcome of
   any of the particular lawsuits, however, could be material to
   the consolidated results of operations of the period in which
   the costs, if any, are recognized. There can be no assurance
   that the Corporation or certain of its subsidiaries will not be
   subjected to significant additional claims in the future or
   that the Corporation's or its subsidiaries' ultimate liability
   with respect to these claims will not present significantly
   greater and longer lasting financial exposure than presently
   contemplated. Although it is probable that future costs will be
   incurred, the amounts cannot reasonably be estimated.
   Accordingly, the Corporation has not made an accrual for such
   costs in its financial statements. In addition, the Corporation
   has retained a law firm to advise it on all matters pertaining
   to these asbestos cases including insurance issues. As a
   result, the Corporation incurred uninsured legal costs
   approximating $600,000 in the first quarter of 2003 and expects
   that such costs are likely to be in excess of $1.5 million in
   the aggregate in 2003.

   With respect to environmental matters, the Corporation is
   currently performing certain remedial actions in connection
   with the sale of real estate previously owned and has been
   named a Potentially Responsible Party at one third-party
   landfill site used by a division which was previously sold.
   Environmental exposures are difficult to assess and estimate
   for numerous reasons including lack

                              - 10 -

   of reliable data, the multiplicity of possible solutions, the
   years of remedial and monitoring activity required, and
   identification of new sites. While it is not possible to
   quantify with certainty the environmental exposure, in the
   opinion of management, the potential liability for all
   environmental proceedings, based on information known to date
   and the estimated quantities of waste at these sites, will not
   have a material adverse effect on the financial condition,
   results of operations or liquidity of the Corporation.

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


Operations for the Three Months Ended March 31, 2003 and 2002

Net Sales.  Net sales for the three months ended March 31, 2003
were $49,679,000 compared to $54,698,000 for the same period of
2002.  A discussion of the first quarter sales for the
Corporation's three segments is included below.  Order backlogs
approximated $113,332,000 at March 31, 2003 in comparison to
$106,088,000 at December 31, 2002.  The increase is due primarily
to an improvement in backlog for the Forged and Cast Rolls segment.

Costs of Products Sold.  Costs of products sold, excluding
depreciation, were comparable for each of the three-month periods
and approximated 78.6% and 78.0% of net sales, respectively.

Selling and Administrative.  The increase in selling and
administrative expenses for the three months ended March 31, 2003
against the comparable prior year period is primarily attributable
to additional legal costs.  See further discussion in the Air and
Liquid Processing paragraph below.

Income from Operations.  Income from operations for the three
months ended March 31, 2003 approximated $771,000, against
$2,437,000 for the three months ended March 31, 2002.  A discussion
of first quarter results for the Corporation's three segments is
included below.

Forged and Cast Rolls.  Although sales for the Forged and Cast
Rolls segment for the three months ended March 31, 2003 were
comparable with sales for the three months ended March 31, 2002,
operating income increased to $957,000 for the quarter.  For the
U.S. operations, despite a small improvement in sales, operating
income was negatively impacted by poor margins as a result of
severe price competition and an increase in natural gas, steel
scrap and other costs. For the U.K. operations, sales declined
slightly from the comparable prior year period; however, while
margins were adversely impacted by poor prices and increases in
steel scrap and other costs operating results benefited from a
lower cost structure resulting from the third quarter 2002
restructuring and income from the sale of technical know-how of
$480,000.  Backlog of orders for both the U.S. and U.K. operations
has increased from a year ago albeit at price levels which continue
to be depressed as the global steel industry customer base
struggles through losses and restructurings.

Air and Liquid Processing.  For the three months ended March 31,
2003, sales for the Air and Liquid Processing segment decreased 22%
to $18,732,000 against the comparable prior year period. In
addition, operating income decreased from $3,199,000 to $1,028,000.
Lower volumes and depressed pricing contributed to the poorer
results.  Specifically, reduced spending in the construction
markets negatively impacted the air handling business which
generally lags the economy whereas lack of demand from power
generation equipment customers affected the pump business.
Although shipments for the heat exchange coil company were modestly
lower than the comparable prior year period, operating income
improved due to a


                              - 12 -

favorable change in product mix. The segment was also impacted by
legal costs incurred for case management and insurance recovery
relating to lawsuits filed in connection with asbestos-containing
products manufactured decades ago.  Backlog of orders for this
segment has declined significantly from a year ago and it is
expected that demand will continue to be weak throughout the year.

Plastics Processing Machinery.  Demand for plastic machinery
components continues to be at low levels.  Sales for the three-
month period ended March 31, 2003 and 2002 were comparable.
Operating income in the first quarter of 2003 improved over the
same period in the prior year due to a lower cost structure arising
from the restructuring undertaken in the third quarter 2002.
Backlog of orders approximates the same level as a year ago.

Other Expense.  Other expense for the three months ended March 31,
2003 was comparable to that as of March 31, 2002.

Income Taxes.  The effective tax rate for the three months ended
March 31, 2003 approximated 62.6% in comparison to 44.4% for the
comparable prior year period.  The increase is due primarily to a
lower tax benefit for operating losses generated in the U.K.,
reduced export sales tax benefit, and the effect of state income
taxes.

Cumulative Effect of Accounting Change.  Effective January 1, 2002,
the Corporation adopted the provisions of Statement of Financial
Accounting Standard (SFAS) No. 142, "Goodwill and Other Intangible
Assets" resulting in an after-tax write off of goodwill amounting
to $2,894,000 in the quarter ended March 31, 2002.

Net Income (Loss).  As a result of all of the above, the
Corporation had net income for the three months ended March 31,
2003 of $197,000 in comparison to a net loss of $1,675,000, for the
three months ended March 31, 2002.

Liquidity and Capital Resources

Net cash flows used in operating activities amounted to $2,499,000
for the three months ended March 31, 2003 in comparison to positive
cash flows of $4,014,000 for the three months ended March 31, 2002.
The decrease is due primarily to lower earnings and changes in
working capital, principally an increase in accounts receivable and
inventories.
Net cash flows used in investing activities approximated $1,187,000
and $1,590,000 in 2003 and 2002, respectively, for capital
expenditures.  As of March 31, 2003, future capital expenditures
totaling $4,902,000 have been approved.  Funds on-hand, funds
generated by future operations and available lines of credit are
expected to be sufficient to finance capital expenditure
requirements.  The Corporation continues to evaluate potential
acquisitions and/or disposals of existing businesses.

Net cash flows used in financing activities were $963,000 for 2003
and $961,000 for 2002 for payment of quarterly dividends at a rate
of $0.10 per share.


                              - 13 -


The Corporation maintains short-term lines of credit in excess of
the cash needs of its businesses.  The total available at March 31,
2003 was approximately $4,800,000.

Litigation and Environmental Matters

See Note 11 of the notes to the consolidated financial statements.

Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 provides a
safe harbor for forward-looking statements made by or on behalf of
the Corporation.  Management's Discussion and Analysis and other
sections of the Form 10-Q contain forward-looking statements that
reflect the Corporation's current views with respect to future
events and financial performance.

Forward-looking statements are identified by the use of the words
"believe," "expect," "anticipate," "estimate," "projects,"
"forecasts" and other expressions that indicate future events and
trends.  Forward-looking statements speak only as of the date on
which such statements are made, are not guarantees of future
performance or expectations and involve risks and uncertainties.
In addition, there may be events in the future that the Corporation
is not able to accurately predict or control which may cause actual
results to differ materially from expectations expressed or implied
by forward-looking statements. The Corporation undertakes no
obligation to update any forward-looking statement, whether as a
result of new information, events or otherwise.  These forward-
looking statements shall not be deemed incorporated by reference by
any general statement incorporating by reference this Form 10-Q
into any filing under the Securities Act of 1933 or the Securities
Exchange Act of 1934 and shall not otherwise be deemed filed under
such Acts.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in the Corporation's exposure to
market risk from December 31, 2002.

                 ITEM 4 - CONTROLS AND PROCEDURES

(a) Disclosure controls and procedures. Within 90 days before
filing this report, the Corporation evaluated the effectiveness of
the design and operation of its disclosure controls and procedures.
Disclosure controls and procedures are the controls and other
procedures designed to ensure that the information required to be
disclosed in reports filed with or submitted to the SEC are
recorded, processed, summarized and reported in a timely manner.
Robert A. Paul, Chief Executive Officer, and Marliss D. Johnson,
Vice President, Controller and Treasurer, reviewed and participated
in this evaluation. Based on this evaluation, Messrs. Paul and
Johnson concluded that, as of the date of their evaluation, the
Corporation's disclosure controls were effective.

(b) Internal controls. Since the date of the evaluation described
above, there have not been any significant changes in the
Corporation's internal accounting controls or in other factors that
could significantly affect those controls.

1.   I have reviewed this quarterly report on Form 10-Q of Ampco-
     Pittsburgh Corporation ("the registrant");

2.   Based on my knowledge, this quarterly report does not
     contain any untrue statement of a material fact or omit to
     state a material fact necessary to make the statements made,
     in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered
     by this quarterly report;

3.   Based on my knowledge, the financial statements, and other
     financial information included in this quarterly report,
     fairly present in all material respects the financial
     condition, results of operations and cash flows of the
     registrant as of, and for, the periods presented in this
     quarterly report;

4.   The registrant's other certifying officer and I are
     responsible for establishing and maintaining disclosure
     controls and procedures (as defined in Exchange Act Rules
     13a-14 and 15d-14) for the registrant and we have:

     a)   designed such disclosure controls and procedures to
          ensure that material information relating to the
          registrant, including its consolidated subsidiaries, is
          made known to us by others within those entities,
          particularly during the period in which this quarterly
          report is being prepared;

     b)   evaluated the effectiveness of the registrant's
          disclosure controls and procedures as of a date within
          90 days prior to the filing date of this quarterly
          report (the "Evaluation Date"); and

     c)   presented in this quarterly report our conclusions
          about the effectiveness of the disclosure controls and
          procedures based on our evaluation as of the Evaluation
          Date;

5.   The registrant's other certifying officer and I have
     disclosed, based on our most recent evaluation, to the
     registrant's auditors and the audit committee of the
     registrant's board of directors (or persons performing the
     equivalent function):

     a)   all significant deficiencies in the design or operation
          of internal controls which could adversely affect the
          registrant's ability to record, process, summarize and
          report financial data and have identified for the
          registrant's auditors any material weaknesses in
          internal controls; and

     b)   any fraud, whether or not material, that involves
          management or other employees who have a significant
          role in the registrant's internal controls; and

6.   The registrant's other certifying officer and I have
     indicated in this quarterly report whether or not there were
     significant changes in internal controls or in other factors
     that could significantly affect internal controls subsequent
     to the date of our most recent evaluation, including any
     corrective actions with regard to significant deficiencies
     and material weaknesses.
