3.6.8 Inner 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. Lay the hose carrier assembly (1) out flat on a level
surface. Stretch the four “male” ends of the hoses
out straight from the hose carrier assembly. Measure
from the male end (2) of each hose back toward the
hose carrier assembly 196" (498 cm) and apply tape
(3) around each hose at that point. The tape is for
proper tensioning of the hoses during reassembly of
the hose clamps.
2. Insert the hose channel assembly (4) into the rear of
the inner boom. Slide the hose channel assembly
into the boom and line up the holes in the mounting
clips (5) with the front mounting holes (6) for the side
wear pads.
Note: Shim ALL side wear pads as needed to maintain
a total minimum gap of .07 to .13" (1,8 to 3,3 mm) in the
horizontal direction.
3. Assemble the lower side wear pads and hose
channel assembly to the inner boom:
a. Apply Loctite
®
242 threadlocker to the threads of
the capscrews (7), saved. Insert a capscrew with
a lockwasher (8), saved, through the lower hole
in the mounting clip (5) and the front mounting
hole of the lower wear pad (9) in the side plates
of the inner boom. Insert the other capscrew and
lockwasher through the rear hole.
b. Place the wear pad shims (10), saved, onto the
capscrews with the holes offset to the center.
Place the wear pad inserts (11), saved, into the
cavities in the wear pad. Be sure the inserts are
seated completely in the cavities. Be careful not
to push the wear pad inserts out of the wear
pads
c. Torque all wear pad mounting capscrews to
31 ±3 lb-ft (42 ±4 Nm).
d. Fill each cavity with a good grade of lithium-based
EP grease.
e. Repeat Steps a thru d to install the lower wear
pad on the other side of the inner boom.
