1. Measure wear in direction X and Y at a point 50 mm (2.0 in.) from the top of the block in each cylinder as shown. If measurements in any cylinder are beyond the Oversize Bore, replace the block. If the block is to be rebored, refer to Step 7 after reboring.

   B or II (X): | 84.987−85.017 mm (3.3459−3.3471 in.)
   B or II (Y): | 84.976−85.006 mm (3.3455−3.3467 in.)
   Service Limit: | 85.050 mm (3.3484 in.)

   Oversize:
   Oversize Piston Diameter+0.050−0.070 mm (0.0020−0.0028 in.)

1. Scored or scratched cylinder bores must be honed..
