How to Shim the Primary Boom
Note: Measure each wear pad. Replace the pad if
it is less than 0.41 inch / 1 cm thick. If the pad is
more than 0.41 inch / 1 cm thick, perform the
following procedure.
1 Extend the boom until the wear pads are
accessible.
2 Loosen the wear pad mounting fasteners.
3 Install the new shims under the wear pad to
obtain zero clearance and zero drag.
4 Tighten the mounting fasteners.
5 Extend and retract the boom through an entire
cycle. Check for tight spots that could cause
scraping or binding.
Note: Always maintain squareness between the
outer and inner boom tubes.
