- Use the J 41507
in order to push up the connecting rod and piston and access the upper connecting
rod bearing.
- Remove the upper connecting rod bearing.
- Wipe the oil from the bearings.

Notice: Do not scrape, shim, or file bearing inserts. If the bearing surface
of the insert is touched with bare fingers, the skin oil and acids will etch
the bearing surface.
Important: Make sure that the connecting rod cap bolt holes and the connecting
rod cap mating surfaces are clean and dry.
- Dip the connecting rod cap bolts in clean engine oil.
- Use clean engine oil in order to lubricate the bearing surface.
- Install the upper connecting rod bearing.

must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the connecting
rod cap bolts.
Tighten
Tighten the connecting rod cap bolts to 27 N·m (20 lb ft).
