Drive and Brake

Systems

The following drive system components should be

inspected periodically to ensure proper operation.

A. Spline lateral movement (slop).

B. Coupling cracked, damaged, or worn.

C. Carrier bearing smooth rotation and bearing support

tight.

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.

Refer to the current Special Tools Catalog for the appro-

priate tool description.



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



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 differential input housing. With the engine stopped

and the ignition switch in the ON position, a momentary

“whirring” sound can be heard each time the drive select

switch is shifted. If no sound is heard, see Electrical Sys-

tem. If the actuator runs constantly or makes squealing or

grinding sounds, the actuator must be replaced.

REMOVING

1. Select LOCK on the drive select switch; then discon-

nect the connector on the actuator harness.

WT504A

2. Remove the floor; then using a T-30 torx wrench,

remove the mounting cap screw from the driveshaft

side of the actuator.

WT529A

3. Remove the mounting cap screw from above the

actuator on the suspension side.

WT530A

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. Remove from the left side.
