Tools Required
ā¢ | J 5239 Connecting
Rod Bolt Guide Set |
- Apply clean engine oil
to the following components:
ā¢ | The connecting rod bearing surfaces |
- Install the J 5239
onto the connecting rod bolts.
- Install the J 8037
onto the piston and compress the piston
rings.
Important: The mark on the top of the piston must face the front of the engine
block.
When assembled, the flanges on the connecting rod and connecting rod
cap should point to the front of the engine block on the left bank and point
to the rear of the engine block on the right bank.
- Install the piston and connecting rod assembly, and the J 8037
into the proper cylinder bore.
- Use the J 8037
and the J 5239
and lightly tap the top of the piston with a wooden hammer
handle.
5.1. | Hold the J 8037
firmly against the engine block until all of the piston rings have entered
the cylinder bore. |
5.2. | Use the J 5239
in order to guide the connecting rod onto the crankshaft journal. |
- Remove the J 5239
from the connecting rod bolts.
Notice: Use the correct fastener in the correct location. Replacement fasteners
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 and nuts.
Tighten
- Tighten the nuts on the first pass evenly to 27 NĀ·m
(20 lb ft).
- Tighten the nuts on the final pass to 55 degrees using
the J 36660-A
.
- Once the piston and connecting
rod assemblies have been installed, lightly tap each connecting rod assembly
(parallel to the crankpin) in order to make sure that the connecting rods
have the proper side clearance.
- Use a feeler gauge or a dial indicator to measure the side clearance
between the connecting rod caps. The connecting rod side clearance measurement
should be 0.15-0.68 mm (0.006-0.027 in).
