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
– Double-check 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 move-
ment.
– 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.
1. Distance between guide cleat and slider shoe
2. Suspension front axle
If the difference between each side exceeds 3 mm
(1/8 in), redistribute drive axle shims as follows:
INSTALLATION
4, Speedometer Drive Insert
If the drive axle to be installed is a new part and
the vehicle is equipped with a speedometer, a cor-
rect size speedometer drive insert must be in-
stalled into the axle end. Ensure that insert is flush
with end of axle.
Position drive axle assembly into location. Install
end bearing housing. Install spacer (if applicable)
between bearing and lower chaincase sprocket.
Install chaincase and position seals (if applicable),
making sure that a gap of approximately 2 mm
(1/16 in) exists between end of bearing housing
and each seal.

CAUTION
Install shim(s) following the pattern shown
in the chart.
