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 machine 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.

Rail Slide Wear

For ease of inspection, all 

Polaris rail slides have a 

wear limit indicator groove 

to indicate the minimum 

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 per-

manent damage to the track 

or rails.

Steering Inspection and Adjustment

Each week, or before a long ride, check all steering system fasteners and 

tighten if necessary.

Thickness

Replace when 

worn to top of

Ski Alignment

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.

NOTE: If the skis are misaligned, we recommend that your dealer cor-

rect the alignment, since camber adjustment may also be 

affected.

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 align-

ment or camber adjustment. See your Polaris dealer.

Ski Skags

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. 

NOTE: Carbide skags must be replaced if any abnormal wear or chip-

ping is found.

Skag Replacement
1. Raise and support the front of the machine so the skis are approxi-

mately 6I (15.2 cm) from the ground.

2. Remove the attaching hardware and pry the skag downward.
3. Remove the rear end of the skag.
4. Remove the front end of the skag.
5. Reverse the steps to install a skag.

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.
