ENGINE / COOLING / HVAC SYSTEM
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 on one side of piston with gap at
the top (12:00 position) or bottom (6:00 position).
IMPORTANT
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 (A) on connecting rod (B). Push piston
pin (C) through rod and piston until it seats against
the installed circlip.
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.
4. Install the remaining circlip (D) with gap at the top
(12:00 position) or bottom (6:00 position). Push the
piston pin in both directions to make sure the clips
are properly seated in the groove.
