Piston Ring End Gap





1. CAUTION: Do not mix up the piston rings. Install the piston rings in the same position and location.

Take the piston ring and use a piston without rings to push the piston ring about 30 mm into the cylinder bore.





2. Using the Feeler Gauge, measure the piston ring gap.
