Boom

Note: ALWAYS replace elastic-lined nuts with new
elastic-lined nuts to help ensure proper fastening.
8. Lift the rod end of the extend/retract cylinder far
enough to insert the threaded stud on the rubber
bumper (Fig. 3-50, 1) into the hole in the extend/retract
cylinder retainer. Secure the rubber bumper in place
with a new 3/8-16 elastic locknut (2). Tighten securely.
Lower the rod end of the extend/retract cylinder, and
allow it to rest on the rubber bumper.
Figure 3-50 Install the Rubber Bumper
Note: Use a hoist with a lifting capacity of 5000 lbs
(2268 kg) and slings to install the outer boom.
9. Lift the outer boom assembly and position the boom
on the frame. Align the mounting plates (Fig. 3-51, 1)
on the frame between the mounting hubs (2) on
each side of the boom assembly. Lower the boom
assembly until the holes in the boom assembly and
the mounting plates align.
Figure 3-51 Install the Outer Boom
10. On the end of the boom pivot pin (Fig. 3 -52, 1),
closest to the capscrew hole, mark the capscrew
mounting hole location. Coat the entire pin with anti-
seize compound.
11. Insert the boom pivot pin (Fig. 3 -52, 1) from the
outside of the boom assembly, making sure that the
marks for the capscrew mounting hole remain in line
with the capscrew mounting holes in the boom
mounting hub. If necessary, use a rawhide hammer
to install the pivot pin.
12. Shim the boom as required using the shims
(Fig. 3-52, 2) to maintain .10" (2,5 mm) maximum
gap (3) between the boom mounting hub and the
self-aligning bearing (4) in the frame. If an additional
shim is required to maintain the maximum gap, the
extra shim MUST be inserted on the right side of the
boom.
