Boom
3.30 Model 6036 Legacy
Note: Shim ALL upper rear wear pads as needed to
maintain a total maximum gap of .06" (1,5 mm) at the
rear of the pads and maintain a total minimum gap of
.07-.13" (1,8-3,3 mm) in the vertical direction.
5. Install the wear pads to the top of the intermediate
boom. Position the wear pads so the outside pads
are offset to the outside and the center pad is offset
to the right as seen in Fig. 3-67.
a. Place the wear pad shims (Fig. 3-67, 1) onto the
top of the boom. Align the holes in the shims with
the holes in the boom. Place the wear pad
inserts (2) into the cavities in the wear pad (3).
Be sure the inserts are seated completely in the
cavities.
b. Apply Loctite
®
242 threadlocker to the threads of
the 3/8-16 x 1" capscrews (Fig. 3-67, 4). Insert a
capscrew with a 3/8" lockwasher (5) and a 3/8"
flat washer (6) through each of the mounting
holes in the top of the intermediate boom. 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 all wear pad cavities with a good grade of
lithium-based EP grease.

6. Before installing the intermediate boom into the
outer boom, place a string for each hose in the outer
boom (heavy enough to pull the attachment tilt and
auxiliary hydraulic hoses) down the inside of the
outer boom. Allow the strings to hang out the rear of
the boom. Pull the other end out the opening on the
left side of the boom where the hoses will exit the
boom. Position the strings all the way to the left side
of the outer boom.
7. Using a hoist capable of lifting 5000 lbs (2268 kg)
and slings, lift the intermediate boom. Carefully slide
the hose reel end of the boom into the front of the
outer boom. Push the boom in until the rod end of
the extend/retract cylinder lines up with the mounts
on the intermediate boom.
8. Remove the slings and the hoist from the
intermediate boom.
9. Install the side wear pads on the outer boom:
a. Slide the intermediate boom over to one side as
far as it will go, to allow wear pad installation.
b. Place the wear pad inserts (Fig. 3-68, 1) into the
cavities of the side wear pads (2). Place the
shims (3) onto the wear pad and align the holes.
c. Apply Loctite ® 242 threadlocker to the threads of
the 3/8-16 x 3/4" capscrews (Fig. 3 -68, 4). Slide
the wear pad with shims between the intermediate
boom and the outer boom with the offset of each
wear pad away from the center. Align the holes
and secure in place with the capscrews (4), 3/8"
lockwashers (5) and 3/8" flat washers (6). Be
careful not to push the wear pad inserts out of
the wear pads.
d. Torque all wear pad mounting capscrews to
31 ±3 lb/ft (42 ±4 Nm).
e. Fill all wear pad cavities with a good grade of
lithium-based EP grease.
f. Slide the intermediate boom all the way over to
the other side to allow wear pads installation.
Repeat Steps a-e to install the side wear pads on
the other side of the outer boom.
