Track Maintenance

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 lock-
nut 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.

1. Place the handlebars in a straight-ahead position. 
2. With only vehicle weight compressing the suspension, measure 

10 inches (25.4 cm) forward from the center of the ski mounting 
bolt. See illustration. At this point, measure between the skis. This is 
measurement X. 

3. Perform the same measurement rearward from the center of the ski 

mounting bolt. This is measurement Y.

4. The X measurement should be 1/8-1/4 inch (3-6 mm) greater than 

the Y measurement. If the skis are misaligned, see your dealer for 
alignment correction as camber adjustment may also be affected.

Ski Skags

WARNING! Worn skis and/or skags will adversely affect handling. Loss of 
vehicle control may result, causing serious injury or death. See your dealer's 
studding chart for recommended skags. If you install longer or more aggressive 
carbide skags than the original equipment, it may also be necessary to add track 
studs to maintain proper vehicle control while turning on hard-packed snow or 
ice.

Check skags before each use of the snowmobile to ensure positive steer-
ing characteristics. Skags must be replaced when worn to half their orig-
inal diameter. 

TIP: Carbide skags must be replaced if any abnormal wear or chipping is found.

Skag Replacement

1. Raise and support the front of the 

snowmobile so the skis are 
approximately 6 inches (15.2 cm) 
from the ground.

2. Remove the attaching nuts and pry 

the skag downward.

3. Remove the front end of the skag.

4. Remove the rear end of the skag.

5. Reverse the steps to install a skag.

Rail Slide Wear

For ease of inspection, all 
POLARIS rail slides have 
a wear limit indicator 
groove to indicate the min-
imum permissible slide 
thickness. Replace the rail 
slides if they are worn to 
the top of the groove at any 
point along their length. 
Failure to do so may result 
in permanent damage to 
the track or rails.
