Snowmobile Arctic Cat (2000 year). Manual - part 121
WISH BONE ARM SUSPENSION
(All Models with
Rubber Mounting Bushings)
Proper setup on the AWS style front-end assembly with
rubber mounting bushings starts by making sure the
wishbone arms are parallel. To check, follow the
procedure below.
1. Lift the front-end assembly high enough so the skis
are off the floor. Place a support under the belly pan.
2. Remove both shock absorbers.
3. Standing in front of the machine, view the wishbone
arms to see if they are parallel with the chassis. If
they are not level, proceed to step 4.
4. Lift each ski assembly separately until it is level or
parallel, then place a support (block of wood) under
the ski to hold arms parallel.
5. Remove the exhaust pipe.
6. Loosen the four bolts securing the upper and lower
wishbone arms to the front end assembly.

7. Lift each ski assembly to maximum travel and set
back down on support. Standing in front, check once
again to make sure arms are parallel.
8. Tighten the four bolts securing the two arms on each
side to 9.7 kg-m (70 ft-lb).
9. Install the shock absorber making sure to tighten the
two mounting bolts.
NOTE: The above procedure is not required on
AWS front-end assemblies having solid bushings in
the A-Arms. The bolts should be checked for proper
torque on these models.
10. Install the exhaust pipe.
NOTE: It is important that the ski tips are slightly
elevated. Preloading the skis in the slightly upward
position enhances the handling characteristics of
the snowmobile.
ADJUSTING SWAY BAR LINKAGE
Fig. 9-9
731-165C
1. Place a lift or stand under snowmobile so the skis
are off the ground and the ski shocks are fully
extended.
2. On the right side, remove the cap screw connecting
the lower ball joint on sway bar linkage.
NOTE: If the sway bar is in proper adjustment,
holes in the suspension bracket and the ball joint
will line up. If they do not line up, the linkage will
need to be adjusted.
3. If the ball joint is lower than the bracket, loosen the
jam nut and shorten the linkage. If the linkage will
not adjust short enough, go to left side and lengthen
linkage until ball joint and bracket holes are lined
up.
4. If the ball joint is above the bracket, shorten the left
side linkage to get alignment. If linkage will not go
short enough, lengthen the right side linkage to get
the alignment.
NOTE: Adjust the linkages so they stay as short
as possible.
5. Install the ball joint into suspension bracket and
secure with a cap screw and lock nut. Tighten to 3.2
kg-m (23 ft-lb).
