Track Maintenance
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
Track adjustment is critical for proper handling. Always maintain
correct tension and alignment.
NOTE: If the track is studded, POLARIS recommends maintaining one (1)
inch (2.54 cm) track tension setting at all times.
1. Verify the track is warmed up and limber. Stop the engine.
NOTICE: Do not use the rear bumper to lift the rear of the snowmobile for track
adjustments.
2. Lift the rear of the snowmobile by the chassis (seat support, x-brace
or running boards) until the track is slightly above the ground.
Safely support the rear of the snowmobile in this position.
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.
4. Measure at the point where the weight is hanging.
