Assembly
NOTE:
•
Prior to beginning the assembly process,
locate the shaft to the vice in the same way as

Locate the right hand bearing and sleeve to the
shaft.
2.
Apply `Loctite 270' to the threads of a new
large-head capscrew. Fit and tighten the capscrew
to
40 Nm.
3.
Identify the balancer drive gear tooth marked with a
dot. Fit the backlash eliminator gear such that the

washer below the circlip exerts considerable
upward pressure and can cause the clip to jump off
during assembly.
Eye damage could result from contact with a
displaced circlip.

An assistant may be required to compress the
belleville washer during fitment of the circlip.
