Track Tension - Polaris 120 Indy Owner's Manual

Maintenance

Track Tension

Track adjustment is critical for proper handling. Always maintain cor-
rect tension and alignment.
1. Operate the
snowmobile to
warm up the track.
2. Stop the engine.
3. Support the rear of
the snowmobile
slightly off the
ground with an
appropriate
snowmobile
support.
4. Hang a 10-pound
(4.5 kg) weight 8
inches (20 cm) from
the center of the
rear idler wheel.
5. Measure the distance between wear surface of the track clip and the
plastic slider at the point where the weight is hanging. Deflection at
this point should be 3/4" (19 mm).
6. If the track tension needs adjustment, follow the procedure on page
64.
TIP: If the rear idler wheel assembly
washers are removed, be sure
they are reinstalled with the
domed side of the washer facing
outward as shown.
