Inspection
-
NOTE:
Do not use a caustic cleaning solution or a wire brush to clean the pistons or damage can occur.
Clean and inspect the (1) ring lands, (2) pin bosses,
(3) skirts and the (4) tops of the pistons. If wear marks, scores or
glazing is found on the piston skirt, check for a bent or twisted
connecting rod.
-
NOTE:
Make sure the oil ring holes are clean.
Using a Piston Ring Groove Scraper, clean the piston ring grooves.
Check
Measure the piston diameter 90 degrees from the piston
pin and piston diameter (DN) height down from the top of the piston at
the point indicated...
