1. ASSEMBLE PISTON AND CONNECTING ROD
(a) Using a small screwdriver, install a new snap ring at one
end of the piston pin hole.
HINT:
Be sure that end gap of the snap ring is not aligned with the pin
hole cutout portion of the piston.
(b) Gradually heat the piston to about 60°C (140°F).
(c) Coat the piston pin with engine oil.
(d) Align the front marks of the piston and connecting rod,
and push in the piston pin with your thumb.
(e) Using a small screwdriver, install a new snap ring on the
