Track Tension - Arctic Cat ZR 5000 Operator's Manual

3. To correct drive belt deflection,
remove the sheave adjuster from the
clutch, remove or add shim washers to
the adjuster, and install the adjuster.
NOTE: Adding shim washers will
decrease belt deflection and removing
shim washers will increase belt deflec-
tion. Available shim washers from Arc-
tic Cat are p/n 0648-714 (0.090 in.) - one
included in the tool kit, p/n 0648-715
(0.030 in.), and p/n 0648-716 (0.060 in.).
NOTE: Removing/adding shim wash-
ers may be done by the snowmobile
owner if qualified to do so. If the owner
does not feel qualified, take the snow-
mobile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
Removing Drive Belt
NOTE: Changing a drive belt can be
done by the snowmobile owner if qual-
ified to do so. If the owner does not
feel qualified, take the snowmobile to
an authorized Arctic Cat Snowmobile
dealer for this service. This service is
at the discretion and expense of the
snowmobile owner.

clutch first; then from the drive clutch.
NOTE: Before installing the drive
belt, use a suitable cleaning solvent to
thoroughly clean the sheaves.
Installing Drive Belt

installed, see Drive Belt Break-In sub-
section in the General Information
section.

ber can be read and the arrows are fac-
ing the front of the snowmobile)
between the sheaves of the drive
clutch first; then between the sheaves
of the driven clutch.
2. Install the cap screw, lock washer,
washer, and sheave adjuster back into
the driven clutch. Tighten the cap
screw (threads coated with blue Loc-
tite #243) to 20 ft-lb.

! WARNING
Never operate the snowmobile with-
out the belt guard/access panel
secured in place.

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 tunnel 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
0743-395
thereafter 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.
