16. If you are replacing the primary intermediate boom
with a new boom section, the following items need to
be removed from the primary intermediate boom:
a. Remove the capscrews (14), lockwashers (15)
and flat washers (16) holding the bottom wear
pad (17) and spacer (18) to the primary
intermediate boom. Label the wear pad and
spacer as “Primary Intermediate Boom Bottom.”
Save the capscrews, lockwashers, flat washers,
spacer and wear pad inserts (19).
b. Remove the capscrews (20), lockwashers (21)
and flat washers (22) holding the upper wear
pads (23) and shims (24) to the primary
intermediate boom. Label the wear pads and

“Primary Intermediate Boom Top Center” or
“Primary Intermediate Boom Top Right.” Save the
capscrews, lockwashers, flat washers, shims and
wear pad inserts (25).
WARNING:
NEVER weld or drill the
boom. The structural integrity of the boom will
be impaired if subjected to any repair involving
welding or drilling. Failure to comply can result
in death or serious personal injury.
