Track Tension
Track tension is directly related to the over-
all 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 tension be
checked daily during the first 300 miles of
operation and once a week thereafter and
adjusted according to need. The track will
stretch and take a “set” during break-in.
Track deflection must be maintained 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
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.

Adjusting Track Tension
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments on both sides of the
snowmobile.

ing bolt jam nuts.

! WARNING
Track tension must be properly
maintained. Personal injury could
result if a track is allowed to become
excessively 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
contact with a rotating track.
