Checking Track Tension
WARNING
DO NOT attempt to check or adjust
track tension with engine running.
Turn ignition key to the OFF posi-
tion. Personal injury could result
from contact with a rotating track.
1. Remove excess ice and snow buildup
from the track, track drive sprockets,
and the inside of the skid frame.
2. Elevate the snowmobile on a
shielded safety stand high enough to
use a spring scale.
3. At the mid-point of the track (on the
bottom side), hook a spring scale
around a track clip; then pull down
on the scale to 9 kg (20 lb). Measure
the deflection (distance) between the
bottom of the wear strip and the
inside surface of the track clip. Mea-
surement should be 50 mm (2.0 in.).
Deflection
NOTE: Measurement is from the
bottom of the wear strip at the
point of the shock pad on the slide
rail.
NOTE: Only tighten track until the
track does not ratchet. Too tight of
a track will cause the rear suspen-
sion to not work properly.
Adjusting Track Tension
NOTE: To ensure proper track
tension adjustment, perform all
adjustments on both sides of the
snowmobile.
1. Loosen the idler wheel axle cap
screws.
