Inspection

CAUTION: Do not use a caustic cleaning solution or a wire brush to clean the pistons or damage may occur.





1. Clean and inspect the (A) ring lands, (B) skirts, (C) pin bosses, and the (D) top of the pistons. If wear marks or polishing are found on the piston skirt, check for a bent or twisted connecting rod.





2. Use Piston Ring Groove Cleaner to clean the piston ring grooves.
^ Make sure the oil ring holes are clean.
