Install
Rotate the crankshaft so the connecting rod journal of the
connecting rod being installed is at bottom dead center. Refer
to Procedure 000-017 in Section 0.
(/qs3/pubsys2/xml/en/procedures/133/133-000-017.html)
Immerse the piston in a container of clean lubricating oil.
Remove the piston from the container. Allow the excess oil
drain from the piston.
Use a clean, lint-free cloth to clean the connecting rods and
bearing shells.
Do not lubricate the backside of the bearing shells. The
operating clearance of the bearing will be reduced and the
bearing can be damaged during engine operation.
If new bearings are not used, the used bearings must be
installed on the same connecting rod from which they were
removed.
Install the upper bearing shell into the connecting rod.
The tang of the bearing shell (2) must be in the slot of the cap
(1). The end of the bearing shell must be even with the cap
mounting surface.
Use Lubriplate™ 105, Part Number 3163086 or equivalent, to
coat the entire inside circumference of the bearing shell.
Apply a film of clean lubricating oil to the cylinder liner.
