7. Measure the piston ring-to-piston ring groove side
clearance.
7.1. Insert the edge of the piston ring into the
piston ring groove.
7.2. Roll the piston ring completely around the
piston.
• If binding is caused by a distorted piston
ring groove, MINOR imperfections may
be removed with a fine file.
• If binding is caused by a distorted piston
ring, then replace the piston ring.
8. Measure the piston ring side clearance with a
feeler gage.
• If the piston ring side clearance is too small,
try another piston ring set.
• If the proper piston ring-to-piston ring groove
clearance cannot be achieved, replace the
piston and pin assembly.
