MAINTENANCE Track Tension WARNING Moving parts can cut and crush body parts. When performing the checks and adjustments recommended on the following pages, stay clear of all moving parts. Never perform track measurement or adjustments with the engine running. Track tension is critical for maximum efficiency and performance. Track tension controls the approach angle of the track to the rail beam in powder snow conditions. Deep snow performance will be optimized at the specified tension. Looser tensions will cause the track to "bunch" in front of the rail tips, causing improper approach angle and poor performance. New tracks will need to be retightened and aligned after the first ride. TRACK TENSION DATA CHART Suspension IQ RMK Weight 10 lbs. (4.54 kg) Measurement Location 16" (40 cm) ahead of rear idler shaft Slack Measurement 3/8"-1/2" (1-1.3 cm) NOTE: Tension adjustments should be made only after the track is warmed up and limber. 1. Turn the engine off. 2. Lift the rear of the snowmobile and safely support it off the ground. 3. Place the recommended weight or downward pressure on the track at the specified distance (see chart) ahead of the center of the rear idler wheel. NOTE: Measure at the point where the weight is placed. 4. Check for specified slack between the wear surface of the track clip and the plastic rail slide. 102

MAINTENANCE
Track Tension
Track tension is critical for maximum efficiency and performance.
Track tension controls the approach angle of the track to the rail beam in
powder snow conditions.
Deep snow performance will be optimized at
the specified tension. Looser tensions will cause the track to “bunch” in
front of the rail tips, causing improper approach angle and poor perfor-
mance.
New tracks will need to be retightened and aligned after the first
ride.
NOTE:
Tension adjustments should be made only after the track is warmed up
and limber.
1.
Turn the engine off.
2.
Lift the rear of the snowmobile and safely support it off the ground.
3.
Place the recommended weight or downward pressure on the track
at the specified distance (see chart) ahead of the center of the rear
idler wheel.
NOTE:
Measure at the point where the weight is placed.
4.
Check for specified slack between the wear surface of the track clip
and the plastic rail slide.
WARNING
Moving parts can cut and crush body parts. When performing the checks and
adjustments recommended on the following pages, stay clear of all moving
parts. Never perform track measurement or adjustments with the engine run-
ning.
