Assembly
The boom must be properly shimmed to function correctly. Each boom section must be shimmed to
a clearance no greater than 0.030” (0.76mm) at its tightest point of travel. It may be necessary to
run each boom section in and out several times to properly identify the tightest point of travel, and to
adjust the number of shims.
After the proper number of shims has been determined, tighten the mounting bolts for that set of wear
pads before moving on to the next step. Apply one (1) drop of Loctite® 242 or equivalent to bolts
securing wear pads and shims. See the Section 4 of this manual for proper torque specifications.
Shims are not used on the larger square wearpads located on the top of the End section and bottom
of the Base Section.
