                        CERTIFICATION OF
                     CHIEF FINANCIAL OFFICER


  I, J. Ronald Hansen, certify that:

     1.I  have  reviewed this quarterly report on  Form  10-Q  of
       Graham Corporation;

     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-15(e) and 15d-15(e)) for the registrant and have:

               a)   Designed   such  disclosure   controls   and
               procedures,  or  caused such disclosure  controls
               and   procedures   to  be  designed   under   our
               supervision, 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
               and   presented  in  this  quarterly  report  our
               conclusions  about  the  effectiveness   of   the
               disclosure controls and procedures as of the  end
               of  the  period covered by this quarterly  report
               based on such evaluation; and

               c)  Disclosed in this quarterly report any change
               in   the   registrant's  internal  control   over
               financial  reporting  that  occurred  during  the
               registrant's  most  recent  fiscal  quarter  (the
               registrant's  fourth quarter in the  case  of  an
               annual  report) that has materially affected,  or
               is  reasonably likely to materially  affect,  the
               registrant's  internal  control  over   financial
               reporting; and

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

               a) All significant deficiencies in the design and
               material weaknesses in the design or operation of
               internal  control over financial reporting  which
               are  reasonably  likely to adversely  affect  the
               registrant's   ability   to   record,    process,
               summarize and report financial information; and

               b)  Any  fraud,  whether or  not  material,  that
               involves management or other employees who have a
               significant  role  in  the registrant's  internal
               control over financial reporting.
