NOTE
Always install a new (matched set) liner when replacing a piston. Distance from top of piston to top
of keystone ring groove is 0.158 inch (4 mm).
CAUTION
Do not stamp top of high ring piston. Piston can be damaged.

products will cause the red (or white) packing to swell, which may result in packing damage during
liner installation.
