Crankshaft and Bearing Installation General
- Install the crankshaft bearings into the engine block and crankshaft
bearing caps.
- Coat the crankshaft bearings with oil.
- Install the crankshaft.
- Install the crankshaft bearing caps with the installed crankshaft
bearing. Be sure that the cap directional arrows point to the front of the
engine.
- Install the crankshaft bearing cap bolts. Thrust
the crankshaft forward in order to align the rear faces of the rear crankshaft
bearings.
Tighten
Tighten all the bolts to 105 N·m (77 lb ft).
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.
- Measure the clearance between the rear crankshaft bearing cap
and the crankshaft thrust surface.

- Install the crankshaft
bearing into the engine block and the crankshaft bearing caps.
- Coat the crankshaft bearings with clean engine oil.
- Install the crankshaft.
- Install the crankshaft bearing caps with crankshaft bearings.
- Be sure that the cap directional arrows point toward the front
of the engine block and the cap is in its original position.

- Install the crankshaft
bearing cap bolts and studs.
- Thrust the crankshaft reward in order to set and align the thrust
bearings and the bearing caps.
- Thrust the crankshaft forward in order to align the rear faces
of the rear crankshaft bearings.
Tighten
- Tighten the bolts on the first pass to 20 N·m (15 lb ft).
- Tighten the bolts on the final pass an additional 73 degrees
using the J 36660-A
.
- Use a dial indicator or
feeler gauge in order to measure end play between the front of the rear of
the crankshaft bearing cap and the crankshaft thrust surface in order to determine
the crankshaft end play.
The proper clearance is 0.05-0.2 mm (0.002-0.008 in).
If you use a feeler gauge, measure between the thrust surface of the
crankshaft bearing and the crankshaft.
