18 flat washers (3/8 ID), and 9 locknuts (3/8 16) through the Upper and Lower
Brush Guard mating point, between the headlight cutouts. Hand-tighten the nuts.
r. Verify the proper positioning of the Lower Brush Guard (P/N 111496-1) and the bolt
holes at the bottom edge of the Lower Brush Guard under the cab door.
s. Torque the eight bolts (3/8 16 x 1.500 LG), on the Lower Brush Guard sides to

5.1.3 Install the Headlights
a. In order to install the Headlight Assemblies, it is necessary to identify which type of
Marker Light is used on the vehicle. Before being removed, the Marker Light was
located just inboard of the Headlight. Inspect the Marker Light and determine whether
an incandescent bulb (i.e., a common lamp bulb) is used inside the light. If an
incandescent bulb is NOT found, install the Headlight Assemblies using Steps b, c, e,
and f, as the Adapter, P/N 111442-1, is not required. If an incandescent bulb IS found,
install using Steps b through f.
b. Install the LH Headlight Bracket (P/N 111418-1) (See Figure 25) using two bolts
(3/8 16 x 1.500 LG) and four washers (3/8 ID) in the top holes. Then, install
three bolts (3/8 16 x 1.500 LG), six washers (3/8 ID), and three locknuts
(3/8 16) in the bottom holes of the Headlight Bracket.
