Tools Required

Important: The crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer position prior to removal. Do not reuse the crankshaft balancer bolt. Install a NEW crankshaft balancer bolt during final assembly.




1. Remove the drive belt. Refer to Drive Belt Replacement .



2. Remove the A/C drive belt. Refer to Drive Belt Replacement .
3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



4. Remove the starter motor. Refer to Starter Motor Replacement in Engine Electrical.



5. Remove the right closeout cover and bolt.



6. Remove the transmission oil cooler lines from the radiator.



7. Remove the power steering cooler, if equipped from the plastic support, if more room is needed.




Important: Make sure that the teeth of the flywheel holding tool mesh with the teeth of the engine flywheel.

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.

8. Install the J 42386-A and bolts.

Tighten
Tighten the J 42386-A bolts to 50 N·m (37 lb ft).




9. Remove the crankshaft balancer bolt.

Do not discard the crankshaft balancer bolt. The balancer bolt will be used during the balancer installation.




10. Using the J 41816 and the J 41816 in order to remove the crankshaft balancer.
11. Remove the J 42386-A and bolts.

Tools Required

Important: 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.

1. Install the J 42386-A and bolts.

Use one M1-1.5 x 120 mm and one M10-1.5 x 45 mm for proper tool operation.

Tighten
Tighten the J 42386-A bolts to 50 N·m (37 lb ft).





Important: The balancer should be positioned onto the end of the crankshaft as straight as possible prior to tool installation.

2. Install the crankshaft balancer onto the end of the crankshaft.



3. Using J 41665 perform the following in order to install the balancer:

3.1.	Assemble the threaded rod, nut, washer and installer.

Insert the smaller end of the installer into the front of the balancer.

3.2.	Use a wrench and hold the hex end of the threaded rod.

3.3.	Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft.

3.4.	Remove the tool and reverse the installation tool.

Position the larger end of the installer against the front of the balancer.

3.5.	Use a wrench and hold the hex end of the threaded rod.

3.6.	Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft.

3.7.	Remove the J 41665 .

4. Install the USED crankshaft balancer bolt.

Tighten
Tighten the USED crankshaft balancer bolt to 330 N·m (240 lb ft).

5. Remove the USED crankshaft balancer bolt.




Important: The nose of the crankshaft should be recessed 2.40-4.48 mm (0.094-0.176 in)

6. 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.




7. Install the NEW crankshaft balancer bolt.

Tighten

1. Tighten the crankshaft balancer bolt a first pass to 50 N·m (37 lb ft).
2. Tighten the crankshaft balancer bolt a second pass to 140 degrees using the J 36660-A .
8. Remove the J 42386-A .



9. Install the power steering cooler, if removed, to the plastic support.



10. Install the transmission oil cooler lines to the radiator.

Tighten
Tighten the oil cooler line connections to 27 N·m (20 lb ft).




11. Install the right closeout cover and bolt.

Tighten
Tighten the closeout cover bolt to 12 N·m (106 lb in).




12. Install the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
13. Lower the vehicle.



14. Install the A/C drive belt. Refer to Drive Belt Replacement .



15. Install the drive belt. Refer to Drive Belt Replacement .
