CAUTION
Generously coat both piston pin bores with a heavy weight
gear oil, such as 85W-140 EP, when assembling the pistons.
Also lubricate the connecting rod bushing. If gear oil is not
available, Lubriplate™, Part Number 3163086, is permissible.
Failure to adequately lubricate the pin joint can result in
extensive engine damage.
Use clean 85W-140 oil to coat the piston pin.
For pistons that are being reused, the piston, piston pin, and
connecting rod must be installed in the same orientation as
when were removed from the engine.
New pistons are symmetrical and do not require a specific
orientation during installation.
Note : Pistons do not require heating to install the pin.
However, the pistons do need to be at room
temperature or above.
Install the pin through the piston and connecting rod.
CAUTION
The snap ring must be seated completely in the piston groove
to prevent engine damage during engine operation.
Install a new snap ring into the piston pin bore.
Install the snap ring with the the gap at the top or bottom of
the piston pin bore.
Install the piston rings. Refer to Procedure 001-047 in Section
1. (/qs3/pubsys2/xml/en/procedures/133/133-001-047-tr-
mixab.html)
