Tunnel/Chassis/Rear 

Bumper/Snowflap 

(F-Series/Z1)

REMOVING/REPLACING TUNNEL

To remove and/or replace a tunnel on a particular snow-

mobile, a number of removing and installing component

sequences must be followed. The technician must in turn

go to the following sections in this manual and refer to

the appropriate removing/installing sub-sections. When

doing these sequences, the technician should use discre-

tion and sound judgment.

A. Section 2 - Engine

B. Section 6 - Drive Train/Track/Brake Systems

C. Section 7 - Rear Suspension

D. Section 8 - Steering and Body

BUMPER/SNOWFLAP 

NOTE: The snowflap can be removed without

removing the bumper by removing the five rivets
securing the snowflap to the heat exchanger and
compressing the two flanged tabs located on the
underside of the tunnel.

0744-462

1. Remove the four machine screws securing the bum-

per to the tunnel; then carefully drill out the rivets

securing the bumper to the tunnel.

0744-931

2. Remove the bumper. 

3. Place the bumper into position on the tunnel; then

install the four machine screws and rivets securing

the bumper to the tunnel. Tighten the screws to 96

in.-lb.

Headlight Assembly 

(Bearcat/F-Series/T-Series/

Z1)

REMOVING HEADLIGHT BULB

NOTE: The bulb portion of the headlight is fragile.

HANDLE WITH CARE. When replacing the headlight
bulb, the bulb assembly must first be removed from
the housing. Do not touch the glass portion of the
bulb. If the glass is touched, it must be cleaned with a
dry cloth before installing.

To access the headlight bulbs, use the following proce-

dure:

1. Remove the two torx-head screws located to the out-

side of the headlight adjustment knobs; then remove

the single torx-head cap screw from beneath the con-

sole (located between the headlights).

743-439A

2. Remove the cap screw and lock nut securing the

front of the headlight assembly to the air silencer.

3. Lift the front of the console enough to allow the

headlight housing to be removed; then remove the

housing.

4. Remove the bulb from the headlight housing and dis-

connect the wiring harness from the bulb.

CAUTION

Use caution when drilling the rivets from the rear bum-
per and snowflap not to damage the heat exchangers.
