PISTON DISASSEMBLY / INSPECTION (1000)

NOTE
New pistons are directional (intake vs. exhaust), but
can be placed in either cylinder.
1. Note location of the piston circlip gap
(12:00 position) or bottom (6:00 position).
2. Remove piston circlip and push piston pin out of
piston. If necessary, heat the crown of the piston
slightly with a heat gun if pin cannot be removed by
hand. Discard circlips.
CAUTION
DO NOT apply heat to piston rings or a loss of radial
tension could result.
