3.9 BOOM WEAR PADS
The wear pads (1) on this vehicle are flat rectangular
wear pads with metal inserts (2).
On the 8042 and 10042 a total of 32 wear pads are
installed on the outer, intermediate and inner booms.
Seven wear pads are attached to the inner boom, 16 to
the intermediate boom, and nine to the outer boom.
On the 10054 a total of 47 wear pads are installed on the
outer, intermediate and inner booms. Seven wear pads
are attached to the inner boom, 16 to the primary
intermediate boom, 15 to the secondary intermediate
boom and nine to the outer boom.
Note: All shims are used to maintain a maximum total
gap of 0.09" (2,3 mm), between the wear pad and the
boom.
3.9.1 Wear Pad Inspection
Inspect all wear pads (3) for wear. If the angle
indicators (4) on the ends of the wear pads are visible, the
wear pads can be reused. If the pads show uneven wear
(front to back), they should be replaced. Replace pads as
a set if worn or damaged.
3.9.2 Boom Wear Pad Replacement
When replacing a wear pad on the boom, replace both
wear pads on that side of the boom; e.g.: replace top front
left and top front right wear pads at the same time.
Usually, shimming will remain the same when installing
new wear pads. All wear pads are secured to the boom
using different capscrews and washers. When installing
new wear pads, apply Loctite
®
#242 (blue) to all wear pad
mounting capscrews and torque to 33 to 38 lb-ft
(46 - 52 Nm).
