2. Remove the sheave adjuster and install
it in its original position (beveled side
out); then install the cap screw, lock
washer, washer, and sheave adjuster

Track Tension
Track tension is directly related to the
overall performance of the snowmobile. If
the track is too loose, it may slap against
the tunnel causing wear or it may “ratchet”
on the track drive sprockets. If extremely
loose, the idler wheels may climb over the
track lugs forcing the track against the tun-
nel causing the track to “lock.”
Arctic Cat recommends that the track ten-
sion be checked daily during the first 300
miles of operation and once a week there-
after and adjusted according to need. The
track will stretch and take a “set” during
break-in. Track deflection must be main-
tained within the recommended range.
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 bot-
tom 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
measurement with the chart.

Adjusting Track Tension
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments
on
both
sides
of
the
snowmobile.
1. Loosen the rear idler wheel adjust-
ing bolt jam nuts.
739-636B
NOTE: On the Bearcat XT, the rear
axle cap screws must also be loosened.
CAUTION
Do not apply Loctite to the driven
clutch cap screw or component dam-
age may occur.
! WARNING
Never operate the snowmobile with-
out
the
belt
guard/access
panel
secured in place.
! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
! 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.
