Removal Procedure
- Remove the air conditioning (A/C) drive belt, if equipped. Refer to
Air Conditioning Compressor Belt Replacement
.
- Remove the accessory drive belt, if not equipped with A/C. Refer to
Drive Belt Tensioner Replacement - Air Conditioning
.
- Remove the fan shroud - lower. Refer to
Engine Coolant Fan Lower Shroud Replacement
in Engine Cooling.
- Remove the starter motor. Refer to

Important:
• | Make sure that the teeth of the J 42386-A
mesh with the teeth of the engine flywheel. |
• | The crankshaft balancer is balanced as an individual component. It is
not necessary to mark the balancer prior to removal. |
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 J 42386-A
and
bolts.
Use one M10-1.5 x 120 mm and one M10-1.5 x 45 mm
bolt for proper tool operation.
Tighten
Tighten the J 42386-A
bolts to 50 N·m (37 lb ft).
- Remove the crankshaft balancer bolt.
Do not discard the crankshaft balancer bolt. The balancer bolt will be used
during the balancer installation procedure.
- Install the J 41816
and J 41816-2
in
order to remove the crankshaft balancer.
- Remove the J 41816
and
the J 41816-2
from the crankshaft
balancer.
- If required, clean and inspect the crankshaft balancer. Refer to
Crankshaft Balancer Cleaning and Inspection
.
Installation Procedure
Important:
• | Make sure that the teeth of J 42386-A
mesh with the teeth of the engine flywheel. |
• | The used crankshaft balancer bolt will be used only during the first
pass of the balancer installation procedure. Install a NEW bolt and tighten as described
in the second, third and forth passes of the balancer bolt tightening procedure. |
• | The crankshaft balancer installation and bolt tightening involves a four
stage tightening process. The first pass ensures that the balancer is installed completely
onto the crankshaft. The second, third, and forth passes tighten the new bolt to the
proper torque. |
Important: The balancer should be positioned onto the
end of the crankshaft as straight as possible prior to tool installation.
- Install the crankshaft balancer onto the
end of the crankshaft.
- Use the J 41665
in order to install the crankshaft balancer.
2.1. | Assemble the threaded rod, nut, washer and installer. |
Insert
the smaller end of the installer into the front of the balancer.
2.2. | Use a wrench and hold the hex end of the threaded rod. |
2.3. | Use a second wrench and rotate the installation tool nut clockwise until
the balancer is started onto the crankshaft. |
2.4. | Remove the tool and reverse the installation tool. |
Position
the larger end of the installer against the front of the balancer.
2.5. | Use a wrench and hold the hex end of the threaded rod. |
2.6. | Use a second wrench and rotate the installation tool nut clockwise until
the balancer is installed onto the crankshaft. |
2.7. | Remove the balancer installation tool. |
- Install the used crankshaft balancer bolt.
Tighten
Tighten the USED bolt to 330 N·m (240 lb ft).
- Remove the used crankshaft balancer bolt.
Important: The nose of the crankshaft should be recessed
2.4-4.48 mm (0.094-0.176 in) into the balancer bore.
- Measure for a correctly installed balancer.
If the balancer
is not installed to the proper dimensions, install the J 41665
and repeat the installation procedure.
- Install a NEW crankshaft balancer bolt.
Tighten
- Tighten the bolt a first pass to 50 N·m (37 lb ft).
- Tighten the bolt a second pass to 140 degrees using J 45059
.
- Remove the J 42386-A
and
bolts.
- Install the starter motor. Refer to
Starter Motor Replacement
in Engine Electrical.
- Install the fan shroud - lower. Refer to
Engine Coolant Fan Lower Shroud Replacement
in Engine Cooling.
- Install the accessory drive belt (if not equipped with A/C). Refer to
Drive Belt Replacement - Accessory
.
- Install the A/C drive belt (if equipped). Refer to
Air Conditioning Compressor Belt Replacement
.
- Perform the crankshaft position (CKP) system variation learn procedure.
Refer to
Crankshaft Position System Variation Learn
