Installation notes
Always install the clip fully into the groove around the piston pin bore. Check that the clip sits evenly and flat in the groove — an incompletely seated clip may pop out. Work on a clean surface and cover openings to the crankcase to prevent clips from falling in. Do not use clips that are bent or damaged.
