If necessary to adjust, loosen the idler wheel (retaining

NOTE: Track tension and alignment are inter-
related. Do not adjust one without the other .
Start the engine and accelerate slightly so that track
turns slowly. Check that track is well centered and turns
evenly . To correct, stop engine then tighten the adjuster
bolt on side where track is closest to the frame. Recheck
alignment.
Retighten the adjuster bolt lock nut, the idler wheel re-
taining bolts and recheck alignment.

WARNING: Before checking track aligment, en-
sure 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. Ensure rio-one is stan-
ding in close proximity to the vehicle.
Lift rear of the vehicle and support it off the ground so
that the track is free to turn. Rotate track by hand and
visually inspect the condition, pay attention to cross links
and rivets. Immediately replace cracked cross links and
loose or/and missing rivets.

WARNING: Do not operate a snowmobile with a
cut, torn or damaged track.

WARNING: Too much tension will result in power
loss and excessive stresses on cross links and
suspension components.

Track Adjustment
Raise the rear of vehicle and support with a mechanical
stand. Allow slide to extend normally. A gap of 6-13 mm
(1/4-1/2")
should exist between slider shoe and cross
links. If the track tension is too loose, the track will have a
tendency to thump.
. . . CAUTION: Do not overtighten the chain sprocket
... adjustment screw.
Track Condition
The tension is correct when there is a deflection fo 6-8
mm
(1/4 5/16")
towards the exterior . Tension is adjusted
by slightly tightening the tensioner sprocket against the
chain and by locking it in position.
