Track Alignment
WARNING
Before checking track alignment, ensure that the track is
free of all particles which could be thrown out while track
is rotating. Keep hands, tools, feet and clothing clear of
track. Always lift the snowmobile on a wide-base stand
with a rear deflector panel. Ensure no one is standing in
close proximity to the snowmobile, especially at the rear of
the track. Never rotate track at high speed.
Centrifugal force could cause debris, damaged or loose
studs, pieces of torn track, or an entire severed track
to be violently thrown backwards out of the tunnel with
tremendous force.
1. Lift rear of vehicle and support it off the ground.
CAUTION
Use proper lifting techniques, notably using your legs force.
Do not attempt to lift the rear of vehicle if it is above your limits.
2. Start engine and accelerate slightly so that track slowly
turns. This must be done in a short period of time (15 to
20 seconds).
3. Check that the track is well centered; equal distance
on both sides between edges of track guides and slider
shoes.
