STANDARD WEAR LIMIT
12,5 in.
Check the pinion damages or wear and replace it
should the wear degree be as the one shown in fig-
ure.
Remove the wheel and check the wear of the rear
sproket teeth. The below figure shows the outline
of teeth in normal and excessive wear. Should the
sprocket be badly worn out, replace it by loosening
the six fastening screws to the hub.
WARNING*: Misalignment of the wheel will re-
sult in abnormal wear and may result in an
unsafe riding condition.
Note*: In muddy and wet conditions, mud sticks to
the chain and sprockets resulting in an overtight
chain. The pinion, the chain, and the rear sprocket
wheel wear increases when running on muddy
ground.
