ENGINE DIVISION SERVICE MANUAL TM 5-4210-230-14&P-1 ENGINE Inspect the exhaust valve seat inserts for looseness, burned   or   cracked   condition.      Use   SE-1951   valve   insert remover, Figure 111, to remove defective inserts.  Position the remover collet into the insert and turn the coned screw out to expand  the  collet  jaws,  thus  providing  a  firm  grip  under  the insert ring.  Use a slide hammer to remove the insert.

Valve insert remover Prior  to  seat  reconditioning,  it  is  desirable  to  clean the  seats  in  order  to  expose  any  cracks  or  other  conditions likely to promote valve failure.  Such inspection is particularly important in engines equipped with hard seat inserts; cracked or loose inserts are not uncommon and are usually caused by improper  installation.    Good  practice  requires  that  the  insert counterbore  in  the  cylinder  head  be  machined  prior  to  insert installation,  Figure  112.    Cutters  are  available  to  dress  both the bottom and circumferential surfaces, but regardless of the method,  the  bottom  of  the  counterbore  must  be  square  to assure good seating of the insert. Before  installing  inserts  they  should  be  thoroughly chilled with dry ice or other means to facilitate their installation in the cylinder head.  Use the installer tool, Figure 113, from the counterbore tool set'SE-1797.  Valve seat inserts supplied for   service   are   standard   size,   .015"   oversize   and   .030" oversize.
