Item 4.  Changes in the Registrant's Certifying Accountants

Battelle  and Battelle LLP  resigned,  with a letter dated May 17, 2004,  as the
independent  accountants  of the Amcast  Industrial  Corporation  401(k)  Salary
Deferral Plan and the Amcast Industrial  Corporation 401(k) Salary Deferral Plan
for Bargaining Unit Employees - Plan 2 (the "401(k) Plans") of Amcast Industrial
Corporation (the "Company" or "Registrant").  Battelle and Battelle LLP provided
no services related to the Company's annual audit of its financial statements.

Battelle and Battelle LLP resigned  because it would no longer  perform  benefit
plan audits of a  publicly-traded  company if Battelle  and Battelle LLP was not
also performing the annual audit of the financial statements.

Ernst and Young LLP is the  Company's  independent  accountants  related  to its
annual audit of its financial  statements.  The relationship between the Company
and Ernst and  Young  LLP has  existed  for  many,  many  years.  The  Company's
relationship with Ernst & Young LLP remains unchanged.

The  reports  of  Battelle  and  Battelle  LLP on  the  401(k)  Plans  financial
statements  for the past two  fiscal  years  contained  no  adverse  opinion  or
disclaimer  of opinion and were not  qualified  or  modified as to  uncertainty,
audit scope or accounting principle.

In connection with the audits of the 401(k) Plans for the two most recent fiscal
years, and through May 17, 2004, there have been no disagreements  with Battelle
and Battelle LLP on any matter of accounting principles or practices,  financial
statement disclosure, or auditing scope or procedure.

During the two most recent  fiscal  years and through May 17,  2004,  there have
been no reportable events (as defined in Regulation S-K Item 304(a)(1)(v)).

The  Registrant  has requested  that Battelle and Battelle LLP furnish it with a
letter  addressed  to the SEC  stating  whether or not it agrees  with the above
statements. A copy of such letter, dated May 17, 2004, is filed as Exhibit 16 to
this Form 8-K.

The  Registrant  engaged  Clark,  Schaefer,  Hackett  and  Company  as  its  new
independent  accounts of the Company's  401(k) Plans financial  statements as of
May 17, 2004.  During the two most recent fiscal years and through May 17, 2004,
the  Registrant  has not  consulted  with Clark,  Schaefer,  Hackett and Company
regarding  either (i) the  application  of accounting  principles to a specified
transaction,  either  completed or proposed;  or the type of audit  opinion that
might be rendered on the  Registrant's  401(k) Plans financial  statements,  and
neither a written  report was  provided  to the  Registrant  or oral  advice was
provided that Clark,  Schaefer,  Hackett and Company  concluded was an important
factor considered by the Registrant in reaching a decision as to the accounting,
auditing or financial  reporting  issue;  or (ii) any matter that was either the
subject of a  disagreement,  as that term is defined  in item  304(a)(1)(iv)  of
Regulation S-K and the related  instructions to Item 304 of Regulation S-K, or a
reportable  event,  as that term is defined in Item  304(a)(1)(v)  of Regulation
S-K.
