cracked, or damaged in any way, replacement is
necessary.
1. Clean all oil-pump components.
2. Inspect the rotors for scoring and gouges.
3. Inspect the alignment pin, driveshaft, and driven
sprocket for damage.
4. Inspect the pump housing and cover for cracks or
damage.
ASSEMBLING/INSTALLING
1. Place the rotors into the pump housing making sure
the alignment pin is in the groove of the rotor.
2. Place the cover onto the pump housing.
3. Secure the pump cover with the Phillips-head screw
coated with red Loctite #271. Tighten to 8 ft-lb.

CLEANING AND INSPECTING
NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.
1. Prior to washing, inspect the oil cooler for signs of
leaks such as oily dirt build-up.
2. Wash the cooling fins using a garden hose and hot,
soapy water and a soft brush.
3. Inspect all mounting brackets and the oil inlet and
outlet for cracks or bends.
INSTALLING
1. Place the oil cooler into position and secure with the
existing hardware. Tighten securely.
2. Connect the oil hoses and secure with the hose
clamps. Tighten securely.
Liquid Cooling System
When filling the cooling system, use premixed Arctic Cat
Antifreeze. While the cooling system is being filled, air
pockets may develop; therefore, open the bleed screw on
the thermostat housing to allow air to bleed from the
cooling system. When clear coolant (no bubbles) is pres-
ent, tighten the bleed screw securely; then fill the cooling
system to the bottom of the stand pipe in the radiator
neck. Run the engine for five minutes after the initial fill,
shut the engine off, and then “top-off” the cooling system
to the bottom of the stand pipe in the radiator neck.
CAUTION
After operating the vehicle for the initial 5-10 minutes,
stop the engine, allow the engine to cool down, and
check the coolant level. Add coolant as necessary.
