Boom
Note: If you are assembling a new outer boom
assembly, continue with Step 4. If reassembling the
existing boom assembly proceed to Step 5.
4. Assemble a new angle indicator decal (13) to the left
side of the boom assembly. Place the hole in the
decal around the weld stud (14) and align the upper
edge of the decal parallel with the top edge of the
boom assembly.
5. Place the two flat washers (15) and the angle
indicator (16) onto the weld stud. Secure in place
with the locknut (17). After tightening the locknut, the
angle indicator must pivot freely on the weld stud. If
the angle indicator binds, loosen the locknut slightly.
Recheck to be sure the angle indicator pivots freely.
6. Assemble new or saved Lift/Lower cylinder
bearings (18) into the Lift/Lower cylinder mounts
(19) on each side of the boom assembly. Orient the
fracture (20) in the outer race of each bearing at the
3 o’clock position. Press the bearings into position
until the edge of the outer race (21) of each bearing
is flush with the edge of the plate (22).
7. Assemble new or saved Slave cylinder bearings (23)
into the Slave cylinder mounts (24) on each side of
the boom assembly. Orient the fracture (20) in the
outer race of each bearing so that it is perpendicular
to the force of the load. Press the bearings into
position until the edge of the outer race (21) of each
bearing is flush with the edge of the plate (22).
8. Assemble the grease fittings (25) into the Lift/Lower
cylinder mounts (19) and the Slave cylinder
mounts (24) on the outer boom. Tighten all grease
fittings.
