Fig. 6-26: Slide Pad Installation (2-Section Shown)

(Ref. Fig. 6-26) As boom pads wear, it becomes necessary to install or
remove shims to maintain the correct clearances. Specific instructions and
clearances for 2-section, 3-section, and 4-section booms are provided on
following pages.
Usually, the main load bearing pads (caged pads) are the only pads that
will need shimming. The other pads are not normally subjected to heavy
wear.

Fig. 6-27: Positioning Retaining Block

(Ref. Fig. 6-27) After shimming caged pads, the retaining block must be
correctly positioned to prevent possible damage to the boom.
Position this edge just below
lower limit of pad chamfer.
