Front Suspension A-Arms (120 Cc Model) - Arctic Cat 660 cc Service Manual

7. Measure the distance from the straightedge to the
right-side ski wear bar bolts in two places: 18-20
cm (7-8 in.) in front of the spindle and 18-20 cm
(7-8 in.) behind the spindle. Record the measure-
ments taken for the right side.
! WARNING
The measurement from the front and rear wear bar
bolts to the straightedge can be equal (ski parallel
to the track), but the front measurement must never
be less (ski toed-in) or poor handling will be experi-
enced. The front wear bar bolt measurement to the
straightedge must not exceed the measurement
from the rear wear bar bolt to the straightedge (ski
toed-out) by more than 3.9 mm (5/32 in.).
8. If ski alignment is not as specified, adjust the
alignment of the ski(s) not parallel to the straight-
edge.
ADJUSTING
NOTE: The following procedure can be used to
adjust the alignment of either ski.
1. Unlock the adjustment tie rod(s) by loosening the
jam nuts.
NOTE: The outside jam nuts are left-hand thread.
Care should be taken to rotate them in the proper
direction.
2. Adjust ski alignment by rotating the adjustment/
steering tie rod.
3. When ski alignment is correct, apply blue Loctite
#242 to the jam nut threaded area and tighten to
1.7-2.1 kg-m (12-15 ft-lb). Tighten both jam nuts
against the tie rod.
! WARNING
Neglecting to lock the tie rod by tightening the jam
nuts may cause loss of snowmobile control and
possible personal injury.

VERIFYING
1. With the handlebar in the straight-ahead position,
verify ski alignment by measuring across from the
outside edge of the left-side wear bar bolts to the
outside edge of the right-side wear bar bolts
(without using the straightedge) in two places:
approximately 18-20 cm (7-8 in.) in front of the
spindle and 18-20 cm (7-8 in.) behind the spindle.
2. The measurement from in front of the spindle to
the outer edge of the wear bar bolts (without using
the straightedge) must not exceed the rear
measurement by more than 1.6-6.4 mm (1/16-1/4
in.) toe-out.
! WARNING
The measurement taken in front of the spindle must
never be less than the measurement taken behind
the spindle or poor handling will be experienced.
Neglecting to lock the tie rod by tightening the jam
nuts may cause loss of snowmobile control and
possible personal injury.
