Important: Be careful not to nick or gouge the piston or the retaining ring groove with the screwdriver if you plan to reuse the piston. If reusing the piston, DO NOT reuse the retainers after removal. Always use new piston pin retainers for assembly.
Notice: You must use a piston ring expander to remove and install the piston rings. Only expand the rings far enough to fit over the piston lands. If the rings are overexpanded, the top ring will shatter and the others will distort.
