Lubrication; Gear Case - Arctic Cat BEARCAT 2015 Operator's Manual

Gear Case

It is very important that the gear case be
flushed and the lubricant be replaced
after each season of use. Arctic Cat rec-
ommends that the flushing and replacing
be done prior to off-season storage.

NOTE: Flushing the gear case and
replacing the lubricant can be done
by the snowmobile owner if qualified
to do so. If the owner does not feel
qualified, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for this service. This service
is at the discretion and expense of
the snowmobile owner
To flush the gear case and replace the
lubricant, use the following procedure:
1. Open the left-side access panel; then
remove the panel and the belt guard.
2. Remove the drive belt (see Drive Belt
sub-section in the Maintenance sec-
tion); then remove the driven clutch.

NOTE: If excessive oil deposits are
noticed, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for service. If not under war-
ranty, this service is at the discretion
and expense of the snowmobile owner.
3. Using Handlebar Stand (p/n 5639-
152) or a suitable substitute, tip the
snowmobile onto its right side.

NOTE: It is recommended that the
gas tank be nearly empty (less than
1/4 full) when tipping the snowmo-
bile.
4. Remove the drain plug from the gear
case; then install a drain adapter fit-
ting with hose into the drain plug
hole.


NOTE: To aid in draining the lubri-
cant, it is advisable to fashion a drain
adapter by acquiring a fitting - Gear
Case Drain Fitting (p/n 0644-552) - and
a length of 3/8-in. hose.
5. Tip the snowmobile back to the
upright position; then place a drain
pan on the floor next to the drain
hose and tip the snowmobile toward
its left side far enough to allow the
lubricant to drain from the gear case
into the drain pan.

NOTE: It is critical that the snow-
mobile is on a level surface to
ensure the lubricant drains properly
and completely.
6. Secure the snowmobile in this posi-
tion until the lubricant is completely
drained.
CAUTION
It is critical that all of the old lubricant
be drained from the gear case prior to
flushing the gear case.
7. When the lubricant has completely
drained from the gear case, tip the
snowmobile back to the upright posi-
tion, remove the drain adapter, and
install and securely tighten the drain
plug; then remove the check/fill plug.
8. Pour Arctic Cat ACT Drive Flush
Fluid (p/n 4639-333) into the check/
fill hole; then install the plug.
Tighten securely.
CAUTION
Do not add more or less than the rec-
ommended amount (6 fl oz) of flush
fluid to the gear case.
