Piston - Ring End Gap

Piston - Ring End Gap

CAUTION: Use care when fitting piston rings to avoid possible damage to the piston ring or the cylinder bore.

CAUTION: Piston rings should not be transferred from one piston to another.

NOTE: Cylinder bore must be within specification for taper and out-of-round.





1. Use a piston without rings to push a piston ring in a cylinder to the bottom of ring travel.





2. Use a feeler gauge to measure the top piston ring end gap and the second piston ring end gap.
