Note: Wear Pad Shimming:
Whenever a shim is used with a pad, a spacer with holes must be inserted between pad & shim.
The wear pad or wear pad insert must not sit directly on the slotted surface of shims.
Add wear pad shims & spacers as required to shim boom to maintain a total minimum gap of 0.070 to 0.130 in (1,8 to 3,3 mm) in
both horizontal & vertical directions.
Wear pad bolts require one hardened washer. However, up to (2) hardened washers may be used except where noted otherwise.
Under no circumstances should more than (2) hardened washers ever be used.
The length of pad bolts depends on the number of the shims used. The bolt cannot extend past chamfer on wear pad.
Add Mystik Tetrimoly Grease (14404793) to all wear pads & all wear pad slide pathways. If applicable, this includes all pad grease
fittings at the rear of boom.
