3.3.4 Outer 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. On the rear of the boom, assemble the extend and
retract bulkhead fittings (17) to the mounting plate on
the right side. Insert the fittings from the bottom up
and secure in place with the bulkhead fitting
nuts (18) on the top side. Tighten securely.
IMPORTANT: Keep the caps on the threaded ends of
the fittings to protect the threads from damage and to
keep dirt and debris out of the fittings.
2. On the rear of the boom, assemble the Attachment
Tilt bulkhead fittings (19) to the mounting plate on
the left side. Insert the fittings from the bottom up
into the set of holes closest to the boom and secure
in place with the bulkhead fitting nuts (20) on the top
side. Tighten securely.
3. If equipped with optional auxiliary hydraulics,
assemble the auxiliary hydraulic bulkhead
fittings (21) to the mounting plate on the left side.
Insert the fittings from the bottom up into the outer
set of holes and secure in place with the bulkhead
fitting nuts (22) on the top side. Tighten securely.
Note: If you are assembling a new outer boom
assembly, continue with Step 4. If reassembling the
existing boom assembly, go to Step 5.
