Primary Boom Components
Part No. 1268515 Z-34/22 Bi-Energy 29
5 Attach a lifting strap from a second overhead
crane or other similar lifting device to the
primary boom lift cylinder.
6 Remove the rear turntable cover.
7 Place a 4x4 inch / 10 x 10 cm block between
the lower compression arms and the cross
member of the upper secondary boom.
Carefully lower the secondary boom onto the
block.
Crushing hazard. Keep hands
away from the block and all
moving parts when lowering the
secondary boom.
8 Remove the pin retaining fasteners from the
primary boom lift cylinder rod-end pivot pin.
Use a soft metal drift to remove the pin.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
9 Lower the rod end of the cylinder onto the
blocks that were placed on the upper
secondary boom.
10 Remove the pin retaining fasteners from the
upper compression arm pivot pin (same side
of machine as the primary boom lift cylinder
barrel-end pivot pin retaining fasteners).
11 Place a rod through the compression arm
pivot pin and twist to remove the pin.
12 Swing the compression arm up out of the way
and secure it from moving.
13 Tag, disconnect and plug the primary boom lift
cylinder hydraulic hoses. Cap the fittings on
the cylinder.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
14 Support the primary boom lift cylinder with
straps or ropes to restrict it from swinging
freely when the barrel-end pivot pin is
removed.
15 Remove the pin retaining fasteners from the
lift cylinder barrel-end pivot pin. Do not
remove the pivot pin.
16 Use the overhead crane to raise the primary
boom 1 inch / 2.5 cm. This will relieve
pressure on the barrel-end pivot pin.
17 Place a rod through the barrel-end pivot pin
and twist to remove the pin.
Crushing hazard. The primary
boom could become unbalanced
and fall when removed from the
machine if not properly attached
to the overhead crane.
18 Attach a lifting strap from an overhead crane
or similar lifting device to the rod end of the
primary boom lift cylinder. Carefully loosen the
straps and allow the barrel end of the primary
boom lift cylinder to slowly swing down.
19 Carefully remove the cylinder from the
machine.
