The piston is attached to the connecting rod by

the piston pin.

When assembling the piston and connecting rod,

make sure to align the mark on the piston head with

the ‘MAG’ mark on the connecting rod.

NOTE 1: Before assembling the connecting rod,

apply oil to its small end.

NOTE 2: Be sure to insert the clips in the two ends

of the piston pin and check the clips for

any play.

(5) CONNECTING ROD

(a) Install the piston and connecting rod assembly into

the cylinder by holding the piston rings with the

rod on the flywheel side. (If you do not have a ring

guide, hold the piston rings with the fingers and

tap the upper part of the piston with a piece of

wood.)

NOTE 1: Apply oil to the piston rings, the large end

of the connecting rod and cylinder before

installing the connecting rod into the

cylinder.

NOTE 2: The piston ring gaps should be positioned

around the piston at 90-degree intervals.
