(5) CONNECTING ROD
(a) Install the piston and connecting rod assembly into
the cylinder by holding the piston rings with the

tap the upper part of the piston with a piece of
wood.)

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.
