Piston / Connecting Rod Assembly
1. Lubricate connecting rod small end, piston pin bore
and piston pin with engine oil.
CAUTION
Do not re-use circlips. Circlips become deformed during
the removal process.
Do not compress the new clip more than necessary to
prevent loss of radial tension. Severe engine damage
may result if circlips are re-used or deformed during
installation.
2. Install a new circlip
1
on one side of piston with gap
at the top (12:00 position) or bottom (6:00 position).
NOTE: Never re-use a piston pin circlip.
If reinstalling the original connecting rods,
orientate the rods the same as when removed. If
new connecting rods are being installed, they
can be installed either way (there is no piston pin
offset in the rod), however it is recommended
they be installed with rods facing the same
direction.
3. Place piston
2
on connecting rod
3
. Push piston pin
4
through rod and piston until it seats against the
installed circlip.
CAUTION
Do not tap on pin or cause any sideways force to
connecting rod. Warm piston crown with a heat gun if
pin cannot be installed by hand, or use a piston pin
installation tool.
DO NOT apply heat to piston rings or a loss of
radial tension could result.
