Installation Procedure

Important:
* 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.

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




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




2. Using the J 41665, install the crankshaft balancer.

1. Assemble the threaded rod, nut, washer and installer. Insert the smaller end of the installer into the front of the balancer.
2. Use a wrench and hold the hex end of the threaded rod.
3. Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft.
4. Remove the tool and reverse the installation tool. Position the larger end of the installer against the front of the balancer.
5. Use a wrench and hold the hex end of the threaded rod.
6. Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft.
7. Remove the balancer installation tool.




3. Install the USED crankshaft balancer bolt (139).

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

4. 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.

5. 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.




6. Install a NEW crankshaft balancer bolt (139).

* 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 EN 47699 and bolt from the block and flywheel.
* Install the transmission bellhousing bolt located at approximately the 10 o'clock position when looking from the rear of the engine.
