Chain Case

Checking Lubricant Level
 NOTE: The snowmobile must be
on a level surface for this procedure.
1. Check the lubricant level in the
chain case by using the sight glass.
NOTE: The correct level is when

the lubricant is at least halfway up in
the sight glass.
NOTE: Adding lubricant can be

done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Yamaha Snow-
mobile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner
2. If the lubricant level is low, remove
the three screws securing the shift
actuator to the chain case, discon-
nect the actuator wiring harness, and
remove the actuator w/extension;
then add appropriate amount of Syn-
thetic Chain Lube through the shift
actuator opening. When the lubri-
cant is halfway up the sight glass,
install the shift actuator w/extension
and connect the actuator wiring har-
ness. Tighten screws to 0.4 kg-m (36
in.-lb).

Lubrication

When installing the shift actuator,
rotate the actuator back and forth to
properly align it with the extension
gear. Failure to do so could cause
component damage.
3. Start the engine and verify proper
