Installation Procedure

WARNING: This page is about a different variant/trim than selected.
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.
