Track Tension - Arctic Cat M 9000 King Cat Operator's Manual

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.
! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
Checking Track Tension
! 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.
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 20
ft-lb. Measure the deflection (distance)
between the bottom of the wear strip
and the inside surface of the track clip.
Measurement should be 51 mm (2 in.).

Adjusting Track Tension

NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments on both
snowmobile.
1. Loosen the idler wheel axle cap
screws.
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.
CAUTION
Always maintain track tension within
recommended specification.
4. Check track alignment.
5. After proper
obtained, tighten the idler wheel
axle cap screws to 34 ft-lb; then
tighten the adjusting bolts securely
against the axle.
