Engine/Transmission
This section has been organized into sub-sections which
show a progression for the complete servicing of the Arc-
tic Cat ATV 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/ transmission.
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 Parts Department.
Removing Engine/
Transmission
Many service procedures can be performed without
removing the engine/transmission from the frame.
Closely observe the note introducing each sub-section for
this important information.
Secure the ATV on a support stand to elevate the wheels.
1. Remove the seat; then remove the left and right side
covers and footwells.
2. Remove the gas tank (see the Fuel/Lubrication/Cool-
ing section).
3. Move the battery cover and disconnect the negative
battery cable.
