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: When indicated for use, each special tool
will be identified by its specific name, as shown in the
chart below, and capitalized.
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
ignition 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. 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.

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.

INSTALLING
NOTE: Make sure to properly align the differential
lock actuator lever with the hole in the differential
lock plunger.
1. Lubricate the O-rings on the actuator; then ensure
that all mounting surfaces are clean and free of
debris.
2. 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.
