Removing and Installing

nector.

2. Remove the two Torx-head screws
securing the taillight to the bracket.
3. Connect the taillight harness connec-
tor; then secure the taillight to the
bracket with the two Torx-head
screws.
Adjusting Headlight Aim
The headlight can be adjusted for vertical
aim of the HIGH/LOW beam. The geo-
metric center of LOW beam zone is to be
used for vertical aiming.
1. Position the snowmobile on a level
floor so the headlight is approxi-
mately 8 m (25 ft) from an aiming
surface (wall or similar surface).
NOTE: There should be an “aver-
age” operating load on the snowmo-
bile when adjusting headlight aim.
2. Measure the distance from the floor
to midpoint of the headlight.
3. Using the measurement obtained in
step 2, make a horizontal mark on
the aiming surface directly in front
of the headlight.
4. Make a vertical mark which inter-
sects the horizontal mark on the aim-
ing surface directly in front of the
headlight.
5. Engage the brake lever lock and start
the engine. Move the headlight dim-
mer switch to the LOW beam posi-
tion. DO NOT USE HIGH BEAM.
6. Observe the headlight beam aim.
Proper aim is when the most intense
beam is centered on the vertical mark
5 cm (2 in.) below the horizontal
mark on the aiming surface.

7. Adjust the headlight using the screw
on the bottom of the headlight until
correct aim is obtained. Shut off the
engine; then disengage the brake
lever lock.
