To install:


NOTE
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.


NOTE
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 fourth passes of the balancer bolt tightening procedure.


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

  1. Position the crankshaft balancer onto the end of the crankshaft.
  2.  
  3. Install the J 41665 and the threaded rod from the J 41478 to crankshaft balancer and install the balancer.
    1. Assemble the threaded rod, nut, washer and installer. Insert the smaller end of the installer into the front of the balancer.
    2.  
    3. Use a wrench and hold the hex end of the threaded rod.
    4.  
    5. Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft.
    6.  
    7. Remove the tool and reverse the installation tool. Position the larger end of the installer against the front of the balancer.
    8.  
    9. Use a wrench and hold the hex end of the threaded rod.
