Piston Ring End Gap

Special Tools:

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 the special tool to measure the top piston ring end gap and the second piston ring end gap.
