Fitting

NOTE: Do not reinstall used piston rings. A special break-in finish, and sometimes an anti-scuff coating; is given to new piston rings by the factory. The purpose of the special finish is to help the new piston rings and cylinder bore mate properly. The special finish, like the crosshatching on the cylinder bore, wears off during break-in. The special finish will be already worn off used piston rings so they probably will not seat properly. For this reason attempting to reuse piston rings could lead to excess oil consumption and possible cylinder scoring.





1. Measure the top piston ring end gap using the Feeler Gauge.
2. Check the piston ring and gap specification.
