Oil Tank Removal/Installation; Component Replacement - Arctic Cat Cougar Service Manual

296
1. To ensure adequate lubrication when bleed-
ing the pump, use a 50:1 pre-mix in the fuel tank.
This gasoline/oil mixture will be used together
with the oil supplied by the injection system.
NOTE
Do not continue to use a 50:1 pre-mix
after bleeding the oil pump unless the
snowmobile is operating in weather con-
ditions where the ambient temperature is
-26° C (-15° F) or colder. Under these
temperature conditions, the 50:1 pre-
mix together with the oil injection system
will help to ensure sufficient engine lu-
brication. Continuing to use the pre-mix
under normal conditions can lead to
spark plug fouling and rapid buildup of
carbon. Refer to Chapter Three for lu-
brication requirements.
2. Check that the oil tank is full (Chapter Three).
3. Check that all hoses are connected to the oil
pump, engine and the oil reservoir tank.
4.
Main
oil
line-
To bleed the main oil supply
line (line between the oil tank and pump):
a. Remove the bleeder screw and washer (A,
Figure 1).
b. Allow oil to bleed from the open port until
there are no air bubbles in the supply hose
or oil leaking from the open port.
c. Install and tighten the bleeder screw and
sealing washer.
WARNING
Never lean into the snowmobile's engine ·
compartment while wearing a scaif or
other loose clothing when the engine is
running or when the driver is attempting
to start the engine. If the scaif or cloth-
ing should catch in the drive belt or
clutch, severe injury or death could oc-
cur. Make sure the belt guard is in place.
5.
Small
oil
lines-
To bleed the small oil lines
(lines between the oil pump and intake), start the
engine and allow it to idle. Hold the pump lever
(B, Figure 1) in the fully open position. When
there are no air bubbles in the hoses (Figure 3),
release the pump lever and tum the engine off.
CHAPTER TEN
NOTE
The carburetors and engine are removed
in Figure 3 for clarity. The engine shown
is typical.

Oil Tank Removal/Installation
Refer to Figure 2, typical for this procedure.
1. Open the hood.
2. Label the hoses at the tank before removal.
3. Detach the wires from the oil level gauge or
remove the gauge from the oil tank (Figure 2).
4. Remove the bolts attaching the oil tank to the
frame.
5. Lift the oil tank up slightly and disconnect the
hoses at the tank. Plug the outlet ports to prevent
oil leakage.
