Slide pads are designed to protect the structural integrity of the boom sections. They 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.

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 the rear cover from the outer boom

Remove screw, wear pad, shims, and spacer from the boom. For ease of installation, keep all parts that were removed together as an assembly.

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.

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.
