Track Alignment

Periodically check that the track is centered and running evenly on the 
slide rails. Misalignment will cause excessive wear to the track and slide 
rail.

1. Safely support the rear of the snowmobile with the track off the 

ground.

2. Start the engine and apply a small amount of throttle until the track 

turns slowly at least five complete revolutions. Stop the engine and 
let the track come to a stop (do not apply brakes). 

3. Inspect track alignment by 

looking through the track 
window to make sure the 
rails (H) are evenly spaced 
on each side. If the track 
runs to the left, loosen the 
idler shaft bolts, then 
loosen the left locknut and 
tighten the left adjusting 
bolt. If the track runs to the 
right, loosen the idler shaft 
bolts, then loosen the right 
locknut and tighten the 
right adjusting bolt.

4. After adjustments are com-

plete, tighten the locknuts 
and torque idler shaft bolts 
to 35 ft. lbs. (47.5 Nm).

5. Repeat steps 2 and 3 to verify proper alignment.

Ski Alignment

WARNING! Improper ski alignment or adjustment may cause loss of steering 
control, resulting in serious injury or death. Do not attempt to change the ski 
alignment or camber adjustment. See your POLARIS dealer.

With the handlebars in a straight ahead position, and with vehicle 
weight compressing the suspension, measure from the straight edge of 
the skis at the center of the ski mounting bolt. The measurement 
between the skis at point X should be 1/8I to 1/4I (3-6 mm) greater than 
the measurement at point Y.

TIP: If the skis are misaligned, we recommend that your dealer correct the align-

ment, since camber adjustment may also be affected.
