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 fourth passes tighten the new bolt to the proper torque.

Important: Make sure the teeth of the tool engage the engine flywheel teeth.

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.

1. 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).





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

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



3. Use the J 41665 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 crankshaft.

3.4.	Remove 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 balancer installation tool.

4. Install the used crankshaft balancer bolt.

Tighten
Tighten the 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) into the balancer bore.

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 .
