GENERAL INFORMATION
The die-cast aluminum housings have been assembled
with thread-rolling screws (trilobular). When assembling
with these screws, start the screws carefully into the
housing; then use the following torque values.
SPECIAL TOOLS
A number of special tools must be available to the techni-
cian when performing service procedures in this section.
NOTE: Special tools are available from the Arctic
Cat Service Department.
Front Drive
Actuator/Differential
Lock
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 igni-
tion switch is in the ON position.
The front drive actuator is located on the side of the front
drive input housing. With the engine stopped and the
ignition switch in the ON position, a momentary “whir-
ring” sound can be heard each time the drive select
switch is shifted or the differential lock is activated. If no
sound is heard, see Electrical System - Front Drive/Dif-
ferential Lock Actuator. If the actuator runs constantly or
makes squealing or grinding sounds, the actuator must be
replaced.
REMOVING
1. Disconnect the connector on the actuator harness.
2. Using a T-30 torx wrench, remove the mounting cap
screw from the driveshaft side of the actuator.

3. Remove the mounting cap screw from below the
actuator on the suspension side.

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.
