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.

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.
