Track Tension

5. Check for specified slack between the wear surface of the track clip 

and the plastic slider. Refer to the Track Tension Data Chart on page 

100. 

If the track needs adjustment:
6. Loosen the rear idler shaft bolt.
7. Loosen the locknuts. 

8. Tighten or loosen the track adjusting screws to provide equal adjust-

ment on both sides of the track.

9. Repeat the measurement on the other side of the track.

TIP: Check more frequently when the snowmobile is new.

10. Start the engine and slowly rotate the track at least five revolutions. 

Let the track come to a stop (do not apply brakes).

11. Check track alignment (see page 102) and adjust as necessary.
12. Tighten the locknuts.
13. Tighten the idler shaft bolts.

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 (+) 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.
