Front Drive Actuator

NOTE: The actuator is not a serviceable compo-
nent. If it is defective, it must be replaced.

NOTE: The actuator will operate only when the
ignition switch is in the ON position.
The front drive actuator is located on the left side of
the front drive input housing. With the engine stopped
and the ignition switch in the ON position, a momen-
tary “whirring” sound can be heard each time the front
drive selector switch is shifted. If no sound is heard,
see Section 5. If the actuator runs constantly or makes
squealing or grinding sounds, the actuator must be
replaced.
REMOVING
1. Remove the left-front inner fender panel; then
disconnect the three-prong connector on the
actuator harness.
2. Using a T-30 torx wrench, remove the mounting
cap screw from the driveshaft side of the actuator.

4. Loosen but do not remove the mounting cap screw
at the front of the actuator; then slide the actuator
to the rear enough to clear the slotted mounting tab
and the selector shaft. Account for an O-ring.

INSTALLING

free of debris.

NOTE: Apply Arctic Cat ATV High-Performance
Grease (p/n 0436-501) to the O-ring surface.
2. Place the O-ring into position; then align the
actuator with the selector shaft and slide it forward
onto the shaft taking care to engage the cap screw
in the slot of the front mounting tab.

3. While holding the actuator firmly forward, tighten
the front cap screw to hold the actuator in place;
then install but do not tighten the two remaining
cap screws.
