Non-Routine Maintenance Section 5 – Procedures
5.6-3 Slide Pads Replacement Procedure
Slide pads are designed to protect the structural
integrity of the boom sections. In addition, slide pads
partially carry the weight of the boom sections and
will wear out over time and based on daily operation.
Ensure to check slide pads quarterly. Refer to Section
5.4-9 for slide pads inspection procedure.
NOTE
The wear pads located at the rear-top and
bottom-front of the boom sections wear faster
than the other wear pads. The basic procedure
for removing wear pads is the same regardless of
their location in the boom assembly.
IMPORTANT
Pay attention to high-load slide pads (Front-Lower
& Rear-Upper of boom) as most of the weight is
exerted on them.

Remove Slide Pads
1. Fully retract the boom.
2. Remove the rear cover from the outer boom.
3. Remove screw, wear pad, shims, and spacer
from the boom. For ease of installation, keep
all parts that were removed together as an
assembly.
For the rear sides of the 2nd and 3rd boom:
4. Before removing the screws from the wear pads,
use a pry bar under the shims of the side wear
pads. The bar prevents the shims from falling
when the screws are removed.
5. Remove the screws, shims, and wear pads
while holding the bar under the shim. For easier
installation, keep all parts removed together as
an assembly.
