NOT A NEW ISSUE BUT FIRST TIME REPORTED UNDER 10 CFR 21. The vendor      
reports cracking at the upper edge of the swivel pad material in an      
adjusting screw assembly, Part Number 1A-7840, used in Enterprise DSR-4  
and DSRV-4 emergency diesel generators. The adjusting screw assembly     
allows for angular movement between the rocker arm and intake and exhaust
valve stems of the power cylinder head. The nuclear power plants at the  
River Bend and Catawba sites are affected. The River Bend licensee       
reported this issue to the NRC on September 29, 1997, in Event           
Notification 33004.
