Boom Centering
5 SECTION BOOM (138’)
On both sides of every boom section (except 5) there are wear pads (1) located near the
bottom of the section, approximately 10’ from the tip end. These pads are used to adjust
each each inner boom section left and right within its respective outer boom section.
1. WEAR PAD
1. Remove the pad plate on both sides. Add shims (1) until the pad plate will not touch the
boom section. Then remove one shim and tighten the inner two bolts. Install the pad plate
and tighten the outer four bolts. To move the boom add and remove shims from the plates.
For every shim added to one side, remove a shim from the other side.
