Figure 13-52: Brushguard Installation (Vehicle w/Winch Shown)

Installation

Using an assistant, place the brushguard on the frame brackets or bumper if the vehicle does not have a winch, and install four
bolts, nuts and washers. Torque the hardware to 81-99 lb-ft (110-134 N•m).

Check the brushguard for level and equal, side to side, spacing from the hood. If adjustment is necessary, loosen the four
alignment bolts and move the brushguard accordingly. Tighten the alignment hardware to 81-99 lb-ft (110-134 N•m).

Remove the lock pins and check for free movement and clearance to the roller fairlead if equipped. Adjust as needed and
reinstall the lock pins.

_____________________________________________________________

NOTE: Dimples have been placed in the fender flares to provide a reference for spacing of the large-flange rivets. You may need
to adjust the drilling position slightly inboard or outboard to maintain adequate material in the wheel well opening for the rivets to
grasp.

CAUTION: Use a drill stop to keep from drilling through the hood outer skin.

Locate the center of the fender flare radius and drill a 3/16” hole through the fender flare and the hood substructure.

Install a 3/16” large-flange pop rivet in the hole and secure the rivet.

Install two evenly spaced rivets in the remaining rear half of the fender flare.

Remove the outboard screw from the clearance light access panel and discard.

Using the supplied screw, install the front L-bracket to the back of the access panel and against the flare.

The bracket should pinch the fender flare to the inside of the wheel well opening (See Figure 13-54).

The lower fender flare extension for the front should be installed on the rear side of the front wheel well opening. The
extensions have been dimpled to provide drill and rivet installation points.

Rear Fender Flares

Installation

Clean the debris from the wheel well opening.

Align the fender flares and extensions with the wheel well opening to locate the best position for installation. The lower fender
flare extension should be installed on the front of the rear wheel well opening.

Position the fender flares and extensions in the wheel wells so the inner edge aligns with the inner lip of the wheel well
openings.

NOTE: Dimples have been placed in the fender flare to provide a reference for installation of the large-flange rivets.

Drill a 3/16” hole in the front of the fender flares and install a 3/16” large-flange rivet.

Install 4 more rivets in the fender flares working from the front to the rear.

Install the rear fender flare extensions using the dimples as a reference for the large-flange rivet placement.

Figure 13-55: Air Filter Restriction Gauge Mounting

Installation

Position the mounting bracket on the A-frame and secure with two 1/8” pop rivets.

Install the air restriction gauge from the engine side and the bezel from the street side of the bracket and secure with two
screws through the bezel into the gauge.

Use pipe thread sealant (Loctite 592) and install the brass hose barb in the air cleaner housing.

Install the hose from the gauge to the hose barb in the air cleaner housing.

where vehicles experience extensive idling. The electrical connector is wired into the engine harness, ready for hourmeter installa-
tion.

Remove the left side cowl cover13-56.

Pull the tabs on either side of the spring clip while simultaneously pulling the spring clip away from the mounting bracket
