Piston Removal - Polaris 2013 RANGER RZR S Service Manual

Piston Removal

1. Remove the circlip. Mark the piston with a white pen
to ensure proper orientation (if reused) during
assembly.
NOTE: If the pistons are to be reused, reassemble
the pistons in the same cylinder and direction from
which they were removed.
NOTE: New pistons are non-directional and can be
placed in either cylinder.
2. Remove piston circlip and push piston pin out of
piston. If necessary, heat the crown of the piston
slightly with a propane torch. CAUTION: Do not apply
heat to the piston rings. The ring may lose radial
tension.
3. Remove top compression ring:
*Using a piston ring pliers: Carefully expand ring and lift
it off the piston. CAUTION: Do not expand the ring more
than the amount necessary to remove it from the piston, or
the ring may break.
*By hand: Placing both thumbs as shown, spread the ring
open and push up on the opposite side. Do not scratch the
ring lands.
