•	The crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer prior to removal.

•	The crankshaft balancer installation and bolt tightening involves a 4 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.

•	Ensure the teeth of the tool engage the engine flywheel teeth.

1. Install the J 42386-A tool  (1) and bolts.

Use 1 M10 - 1.5 x 120 mm and 1 M10 - 1.5 x 45 mm bolt for proper tool operation and tighten the J 42386-A tool bolts to 50 N·m (37 lb ft).





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

2. Position the balancer (138) onto the end of the crankshaft.



3. Use the J 41665 installer and the J 41478 installer in order to install the balancer.

3.1.	Assemble the J 41478 installer threaded rod, nut, washer and the J 41665 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 balancer installation tools.




4. Install the NEW crankshaft balancer bolt (139) and

4.1.	Tighten the crankshaft balancer bolt a first pass to 150 N·m (110 lb ft).

4.2.	Loosen the crankshaft balancer bolt a second pass 360 degrees.

4.3.	Tighten the crankshaft balancer bolt a third pass to 50 N·m (37 lb ft).

4.4.	Tighten the crankshaft balancer bolt a final pass 230 degrees using the J 45059 meter .

5. Remove the J 42386-A tool .
