1. Start the engine and let it idle and
warm up until the engine reaches
operating temperature, or if the
snowmobile was operated, allow the
engine to idle for approximately 30
seconds.
2. Shut the engine off. Remove the
access panels and the hood.
3. Remove the torx-head screws and
the rear access plate from beneath

5. Using Oil Filter Wrench, loosen (but
do not remove) the oil filter and
allow the oil to drain from the filter
into the drain pan; then remove the
filter.
NOTE: Ensure the O-ring is
removed with the oil filter. If the O-
ring remains attached to the crank-
case, oil leakage may occur.
6. Apply a light coat of fresh engine oil
to the seal of the new oil filter.
7. Install the new oil filter by turning
the oil filter by hand until the seal
has contacted the oil filter mounting
surface; then tighten the oil filter to
1.7 kg-m (12 ft-lb).
8. Install the engine oil drain screw
with a new gasket. Tighten the screw
to 1.0 kg-m (7.2 ft-lb).
9. Install the rear access plate. Tighten
the screws to 1.2 kg-m (9 ft-lb).
10. Remove the four torx-head screws
securing the right-side footrest to the
tunnel and the support; then with a
drain pan in position, remove the
drain plug from the oil tank.

NOTE: To aid in draining the oil
from the tank, position a funnel
between the tank and the opening
of the tunnel running board.
11. After the oil has drained completely,
install the drain plug with a new O-
ring and tighten to 2.2 kg-m (16 ft-
lb).
12. Install the four screws securing the
right-side footrest. Tighten the
screws to 50.5 kg-m (44 in.-lb).
13. Pour 2.8 L (3 US quarts) of engine
oil in through oil tank fill hole.
14. Install the oil tank plug then start the
engine and let it idle. The oil pres-
sure light may illuminate briefly
after starting but should go out
within 10 seconds. If the light does
not go out within 10 seconds, the
engine will automatically shut
down. If a shutdown occurs check
that there are no leaks and that oil
has been added to the oil tank before
trying to start the engine again. If the
engine shuts down automatically, the
key will have to be turned off for 5
seconds before the engine can be
restarted. If the light does not stay
off after starting the engine a second
time, take the snowmobile to and
authorized Yamaha Snowmobile
dealer for service.
15. Shut the engine off; then look at the
oil level tube on the backside of the
oil tank. The oil should be above the
MIN line but not above the MAX
line.
