Correcting Offset; Adjusting Center-To-Center Distance; Drive Belt Deflection - Arctic Cat Wildcat EFI 1994 Service Manual

CORRECTING OFFSET
1. To correct offset, the driven pulley must be
moved laterally on the driven shaft. Remove the
cap-lock screw and washers securing the
driven pulley; then remove the driven pulley.
2. To move the driven pulley inward on the shaft,
remove washer(s) as required.
3. To move the driven pulley outward on the shaft,
add additional alignment washer(s) behind the
driven pulley.
NOTE: When the correct offset is attained,
use the large and small alignment washers
to correctly position the driven pulley on the
driven shaft. Arrange washers to allow the least
amount of "float" on the driven shaft. A maxi­
mum of one washer thickness "float" is allow­
able. Apply a light coat of grease to the shaft.
4. Install the driven pulley and secure with a cap­
lock screw and washers. Tighten the screw to
2.6-3.3 kg-m (19-24 ft-Ib).
5. Install the drive belt and secure the clutch
shield.
NOTE: After you have checked and
adjusted the offset, you must check for
proper drive belt deflection. This is very critical
for optimum performance (see Drive Belt
Deflection section).
ADJUSTING CENTER-TO-CENTER
DISTANCE
To adjust the center-to-center distance, there are
three shim plates provided on the rear PTO-side
motor mount bolt. To adjust use the following proce­
dure:
1. Remove the driven clutch.
2. Using a 3/8 in. Allen-head wrench, loosen the
rear PTO-side motor mount bolt.
3. Move the required number of shim plates for­
ward to achieve the 28.9 cm (11.375 in.) ceD­
ter-to-center distance between the drive clutch
and driven pulley.
4. Using a 3/8 in. Allen-head wrench, tighten the
rear PTO-side motor mount bolt. Torque to 4.2
kg-m (30 ft-Ib).

DRIVE BELT DEFLECTION
Drive belt length, condition, and deflection are aJ
important for peak performance. To check and
adjust drive belt deflection, use the following proce­
dure.
1. Turn the engine OFF; then oRen the clutch
shield.
2. Make sure the drive belt is sitting at the top of
the driven pulley sheaves.
3. Place a straightedge on top of the drive belt
The straightedge should reach from the drive
clutch to the top of the driven pulley.
4. Using a stiff ruler centered between the
clutches, push down on the drive belt just
enough to remove all slack. Note the amount of
deflection on the ruler at the bottom of the
straightedge. The deflection should be within
the range of 25.4-31.8 mm (1-1
%
in.).
AF122
NOTE: Only push down on the belt with the
ruler until you see the bottom of the belt
flex upward; then read the amount of deflection.
5. To correct drive belt deflection, washers can be
removed or added between the stationary and
movable sheave of the driven pulley.
NOTE: If the drive belt deflection is above
specifications, the snowmobile will bog
and lack power at clutch engagement. For good
performance, proper belt deflection is a must.
6. Secure the clutch shield.
