Checking Track Tension
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 mid-point of the track (on the
bottom side), hook a spring scale
around a track clip; then pull down
on the scale to the recommended
pressure. Measure the deflection
(distance) between the bottom of the
wear strip and the inside surface of
the track clip. Compare the measure-
ment with the chart.
0746-788
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 suspension
to not work properly.
Adjusting Track Tension
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments on both sides of the
snowmobile.
1. Loosen the idler wheel axle cap
screws.
0745-811
NOTE: On RR models using Axle
Nut Spanner Wrench (p/n 0644-558)
from the tool kit, loosen the right-
side rear axle nut.
0744-067
NOTE: On RR models, always
loosen the right-side rear axle nut
when adjusting track tension/align-
ment. The left-side rear axle nut is
secured with green Loctite #609 and
should not be loosened or removed.
2. If the deflection (distance between
the bottom of the wear strip and the
inside surface of the track clip)
exceeds specifications, tighten the
adjusting bolts to take up excessive
slack in the track.
3. If the distance between the bottom of
the wear strip and the inside surface
of the track clip is less than specified,
loosen the adjusting bolts to increase
the slack in the track.
4. Check track alignment (see Track
Alignment sub-section in this sec-
tion).
! WARNING
DO NOT attempt to check or adjust
track tension with engine running.
Turn ignition key to the OFF position.
Personal injury could result from con-
tact with a rotating track.
