assembly.
Do not confuse the top and second rings.
Space the ring end gaps 120 degrees apart.
Space the side rail gaps 40mm or more apart as shown.
After installation, the rings should rotate freely in the
ring grooves.

PISTON INSTALLATION

the clip from falling into the crankcase.
Install the piston and insert the piston pin.

facing the correct direction.
