How to Shim the Primary Boom
Measure each wear pad. Replace
the wear pad if it is less than
0.41 inches (1 cm) thick. If the
wear pad is more than 0.41 inches
(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.

5 Extend and retract the boom through an entire
cycle. Check for tight spots that could cause
scraping or binding.
Always maintain squareness
between the outer and inner boom
tubes.
