MAINTENANCE PROCEDURES
Reverse Activation
NOTE:
The reverse may not activate
or may be harder to activate if the drive
belt is positioned too high in the driven
pulley. If reverse activation does not
work properly, ensure the drive belt is
properly adjusted. Adjust the drive belt
lower in the driven pulley if needed.
Drive Pulley
Drive Pulley Adjustment
The drive pulley is factory calibrated for
sea level operation.
550F and 600 ACE
No adjustment required.
600 HO E-TEC
WARNING
Remove the tether cord cap from
engine cut-off switch before per-
forming any adjustment. Vehicle
must be parked in a safe place,
away from the trail.
The drive pulley is factory calibrated to
transmit maximum engine power at a
predefined RPM. Factors such as am-
bient temperature, altitude or surface
condition may vary this critical engine
RPM thus affecting snowmobile effi-
ciency.
This adjustable drive pulley allows set-
ting maximum engine RPM to maintain
maximum power.
Calibration screws should be adjusted
so that actual maximum engine RPM
matches the maximum horsepower
RPM.

8100 RPM (± 100)
NOTE:
Use precision digital tachome-
ter for engine RPM adjustment.
NOTE:
The adjustment has an effect
on high RPM only.
There are 6 positions numbered 1 to 6.
The calibration screws have 6 different
settings identified by numbers scribed
on their head.
The actual setting is the screw head
number aligned with the mark on the
pulley.

PULLEY SETTING

2. Number
Each position modifies maximum en-
gine RPM by approximately 200 RPM.
Lower position numbers decrease en-
gine RPM in steps of 200 RPM and
higher position numbers increase it in
steps of 200 RPM.
Example:
Calibration screws initially set at posi-
tion 4 and changed to position 6 will
increase maximum engine RPM by
400 RPM.
Procedure
Loosen the lock nut just enough to get
the calibration screw head out of the
pulley and rotate to the desired posi-
tion. Do not completely remove the
lock nut.
Set all 3 calibration screws to the same
position.
Tighten lock nuts to 10 N•m ± 2 N•m
(89 lbf•
in
± 18 lbf•
in
).
