DRIVE CLUTCH AND DRIVEN
PULLEY
— Keeping the drive clutch
and driven pulley clean should be the pri-
mary consideration of the operator. The
drive clutch and driven pulley 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 PULLEY
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 pulley is serviced.
NOTE: For checking offset, it is
necessary to use Clutch Alignment
Bar (p/n 0644-428) to obtain a drive
clutch/driven pulley 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; then
remove the belt guard.
2. Install the clutch alignment bar
between the drive clutch sheaves.
3. Allow the bar to rest on the drive
clutch shaft and against the outside
edge of the driven pulley 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 pulley 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
0.060 in. clearance at point C. At
this point, measurement between
points A and C should be 1.507 in.
(with a maximum 0.060 in. clear-
ance). If the bar either will not clear
the inside edge or is more than the
specified amount, the offset must be
corrected.
0745-177
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 800 cc and turbo
models for optimum performance, use 91
octane (minimum) gasoline.
