SUSPENSIONS AND WHEELS
REAR WHEEL OVERHAUL
Proceed as follows for the wheel bearing and flange substitution,
the wheel rim check and the wheel spindle for deformation check.
• Check the bearings and the flexible joints for wear. If necessary,
substitute them.
When reassembling the rear wheel, it is necessary to check the chain
tension and the wheel alignment by adjusting the index adjusters 1
on both sides of the fork.
CHAIN, CROWN WHEEL AND PINION WHEEL
OVERHAUL
The figure demonstrates the teeth profile of the crown wheel and the
pinion wheel under normal conditions and under conditions of
excessive wear.
If excessive wear is noted, substitute the various components.
CROWN WHEEL SUBSTITUTION
After having removed the rear wheel, remove the crown wheel
support flange.
As indicated in the figure, keep the screws 2 steady. Slacken the
relative flange nuts.
When reassembling, apply a little LOCTITE 243 to the thread of the
screws. Use new nuts and tighten them to the torque pressure of
22.5-24.5 N.m
When substituting the crown wheel, always substitute the
pinion wheel and the transmission chain.
