Engine/Transmission

This section has been organized into sub-sections which

show a progression for the complete servicing of the Arc-

tic Cat ROV engine/transmission.

To service the center crankcase halves, the engine/trans-

mission must be removed from the frame. To service top-

side, left-side, and right-side components, the engine/

transmission does not have to be removed from the

frame.



NOTE: Arctic Cat recommends the use of new gas-

kets, lock nuts, and seals and lubricating all internal
components when servicing the engine/ transmis-
sion.



NOTE: A new ATV and an overhauled ATV engine

require a “break-in” period. The first 10 hours (or 200
miles) are most critical to the life of this ATV. Proper
operation during this break-in period will help assure
maximum life and performance from the ATV. Instruct
the customer to follow the proper break-in procedure
as described in the Operators Manual.

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: Special tools are available from the Arctic

Cat Service Department.
