DRIVE CLUTCH AND DRIVEN
CLUTCH
— Keeping the drive clutch
and driven clutch clean should be the pri-
mary consideration of the operator. The
drive clutch and driven clutch can be
cleaned of any drive belt accumulation
using compressed air. The sheaves can be
cleaned using a clean cloth and parts-
cleaning solvent.
DRIVE CLUTCH/DRIVEN CLUTCH
OFFSET
— If premature drive belt wear
is experienced or if the drive belt turns
over, offset must be checked. Also, offset
must be checked whenever either the
drive clutch or driven clutch is serviced.
NOTE: For checking offset, it is
necessary to use Clutch Alignment
Bar (p/n 0644-428) to obtain a drive
clutch/driven clutch offset of 1.485
in. This special tool can be pur-
chased from an authorized Arctic
Cat snowmobile dealer.
To check offset, use the following proce-
dure.
1. Open the left-side access panel and
unlock the quarter-turn screw secur-
ing console; then move the console
up and out of the way.
2. Install the clutch Alignment Bar (p/n
0644-428) between the drive clutch
sheaves.
3. Allow the bar to rest on the drive
clutch shaft and against the outside
edge of the driven clutch stationary
sheave.
NOTE: The alignment bar must
extend beyond the front edge of the
drive clutch.
4. With the bar against the outside edge
of the driven clutch stationary
sheave at points A and B, the bar
should just clear the inside edge of
the stationary sheave of the drive
clutch and rest on the stationary
shaft at point C with a maximum
0.76 mm (0.030 in.) clearance at
point C. At this point, measurement
between points A and C should be
37.72 mm (1.485 in.) with a maxi-
mum 0.76 mm (0.030 in.) clearance.
If the bar either will not clear the
inside edge or is more than the spec-
ified amount (see chart), the offset
must be corrected.
0746-808
NOTE: If the offset is out of speci-
fication, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for drive system evaluation
and/or servicing. This service is at
the discretion and expense of the
snowmobile owner.
GASOLINE
— On the 8000 for opti-
mum performance, use 91 octane (mini-
mum) gasoline.
