– Pull drive axle toward the end bearing housing
and take note of the measurement between
sprocket and tunnel.
The drive axle axial play is the difference between
these 2 measurements.
– Repeat this procedure 2 or 3 times to obtain an
accurate measurement.
The allowable drive axle axial play is 0 to 1.5 mm
(0 to .060 in).
The drive axle axial play, as calculated above,
should be within the allowable axial play, add
shim(s) accordingly.
– Remove drive axle, install required shim(s) as
per the shim position chart, reinstall drive axle
without the suspension and track.
SHIM POSITION
Shim position is important to maintain proper
sprocket alignment.
When installing shims between the chaincase
and the drive axle bearing, there must be same
quantity of shims between the drive chain sprock-
et and spacer.
1. Chaincase
2. Spacer
3. Same quantity
– Doublecheck drive axle axial play as described
above.
– Modify total shim thickness as required.
– Reinstall track and suspension. Adjust track
tension and alignment.
NOTE: Center the track suspension to ensure
that the alignment check made in the next step is
accurate.
– To center, grasp the track suspension and move
it sideways, left and right. Position the track
suspension at the midpoint of its sideways
movement.
– Check track front alignment by measuring the
gap, on each side between guide cleat and the
slider shoe, behind the suspension front axle as
shown.
