3.6.1 Inner Boom Removal
1. Remove any attachment from the quick attach
assembly. (Refer to Section 3.10.1, “Disconnecting
from an Attachment.”)
Note: If you are replacing the inner boom with a new
inner boom, remove the quick attach from the inner
boom. (Refer to Section 3.10.3, “Quick Attach Removal.”)
2. Park the vehicle on a hard, level surface. Be sure
there is enough room in front of the vehicle to allow
the inner boom section to be removed from the front
of the boom assembly.
3. Fully retract the boom and raise the boom to a
horizontal position. Place the travel select lever in
(N) NEUTRAL, move the neutral lock lever to the
NEUTRAL LOCK position, engage the parking brake
switch and shut the engine OFF. Allow the hydraulic
oil to cool before proceeding.
4. Move the Attachment Tilt joystick in both directions
to relieve any trapped pressure in the Attachment Tilt
system. Move the auxiliary hydraulic joystick in both
directions to relieve any trapped pressure in the
auxiliary hydraulic system.
5. Locate the two hoses (1) attached to the base of the
Attachment Tilt cylinder (2) inside the gooseneck (3).
6. Label and remove the hoses (1) from the elbow
fittings (5) on the Attachment Tilt cylinder. Plug the
hose ends and cap the elbow fittings on the
Attachment Tilt cylinder to prevent dirt and debris
from entering the hydraulic system and/or cylinder.
7. Label and remove the two auxiliary hydraulic
hoses (6) from the bulkhead fittings (7) inside the
gooseneck (8). Plug the hose ends and cap the
bulkhead fittings to prevent dirt and debris from
entering the hydraulic system.
8. If you are replacing the inner boom with a new inner
boom, remove the female coupler (9) male
nipple (10) and bulkhead fittings (7) from the
bulkhead plate inside the gooseneck. Save all the
hardware for reassembly.
