Intermediate Boom Installation

IMPORTANT: Light lubrication of the boom wear
surfaces with a rust inhibitor/lubricant such as LPS 3 or
equivalent is recommended to keep the boom wear
surfaces lubricated properly. Light lubrication of the boom
wear surfaces is also recommended in salt air climates
and when the vehicle is stored, to help prevent rusting.

1. At the rear of the intermediate boom, assemble the

retract chain sheave (Fig. 3-68, 1) to the mounting
ears on the right side of the boom. Place the sheave
between the ears and insert the sheave pin (2) from the
left side. Align the hole in the pin retainer plate with the
threaded hole in the left ear. Secure the pin in place
with the 1/2-13 x 1" capscrew (3), saved, and the 1/2"
lockwasher (4), saved. Tighten the capscrew securely.

2. Apply grease to the grease fitting (Fig. 3-68, 5) in

the pin. Spin the sheave by hand to ensure the sheave
spins freely on the pin and to distribute grease evenly.

Figure 3-68 Retract Chain Sheave

Note: Shim ALL side wear pads as needed to maintain
a total minimum gap of .07-.13" (1,8-3,3 mm) in the
horizontal direction.

3. Assemble the hose reel assembly, left side and

bottom wear pads to the rear of the intermediate boom:

a. Apply Loctite® 242 threadlocker to the threads of

the two 3/8-16 x 1" capscrews (Fig. 3-69, 1),
saved. Insert a capscrew with a 3/8" lockwasher
(2), saved, and a 3/8" flat washer (3), saved,
through each of the mounting holes in the left
side plate of the hose reel assembly. Place three
3/8" flat washers (3), saved, onto each of the
capscrews and insert the capscrews through the
mounting holes in the left side of the boom.

b. Place the wear pad shims (Fig. 3 -69, 4), saved if

present, onto the capscrews. Place the shims
onto the capscrews with the holes offset as noted
in disassembly.
