Chaincase Oil - Arctic Cat Cougar Service Manual

LUBRICATION, MAINTENANCE AND TUNE-UP 75
Chaincase Oil
Oil in the chain housing lubricates the chain
and sprockets. Transmission Lube (part No.
0636-817) is available from Arctic Cat dealers.
Different types or brands will often vary slightly
in their composition and a mixture of the two
may not lubricate as well as either alone. Always
try to use one type and brand of oil.
Oil level check
The chain housing oil level is checked with the
dipstick (Figure 2).
1. Park the snowmobile on a level surface. Open
the hood.
2. Unscrew and remove the dipstick (Figure 2)
from the chaincase cover. Wipe the dipstick off
and insert it back into the chaincase. Do not
screw the dipstick back into the cover.
3. Lift the dipstick out of the chaincase and
check the oil level on the dipstick. The oil level
should be between the upper and lower marks on
the dipstick.
4. If the oil level is low, top off with chaincase
oil. Do not overfill. Recheck the oil level.
5. Reinstall the dipstick. Tighten it securely.
Changing oil
Oil in the chaincase should be changed once
each year or every 1,000 miles. The manufac-
turer suggests draining and filling with new oil
when preparing the machine for summer storage.
1. Park the snowmobile on a level surface.
2. Open the hood.
3. Remove the exhaust pipe and muffler as de-
scribed in Chapter Eight.
4. Place an old carpet scrap or several shop
cloths under the chaincase cover to absorb
spilled oil.
NOTE
Oil can be drained from late models by
removing the drain plug (Figure 3) from
the back of the chaincase. However, it is
necessary to remove the chaincase cover
from models not equipped with a drain
plug. Try to catch as much of the spilled
oil as possible in shop cloths.
5A. On later models, remove the drain plug
(Figure 3) and drain oil from the chaincase. The
cover can be removed from the chaincase for
inspection and cleaning if desired.
5B. To remove the chaincase cover, proceed as
follows:
a. Remove the screws and washers attaching
the cover (Figure 2) to the chaincase.
b. Remove the cover and 0-ring (Figure 4).
c. Clean the chaincase cover thoroughly. Re-
move as much oil from the bottom of the
chaincase as possible.
d. Inspect the chaincase cover 0-ring andre-
place if necessary. See Figure 4.
