Jib Boom, Z-45/25J Models
How to Remove the Jib Boom
Perform this procedure with the
boom in the stowed position.
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation. Refer to
Section Two,
Hydraulic Hose and
Fitting Torque Specifications.
1 Remove the platform. See 2-1,
How to Remove the Platform.
2 Remove the platform mounting weldment
and the platform rotator. See 2-3,
How to
Remove the Platform Rotator.
3 Remove the hose and cable cover from the side
of the jib boom.
4 Attach a lifting strap from an overhead crane to
the jib boom.
5 Tag, disconnect and plug the jib 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.
6 Support the barrel end of the cylinder with a
suitable lifting device.
7 Remove the pin retaining fastener from the jib
boom lift cylinder barrel-end pivot pin.
8 Use a soft metal drift to remove the pin and let
the cylinder hang down.
9 Remove the pin retaining fastener from the jib
boom pivot pin. Use a soft metal drift to remove
the pin, then remove the jib boom from the
primary boom bellcrank.
Crushing hazard. The jib boom
may become unbalanced and fall
when it is removed from the
machine if it is not properly
attached to the overhead crane.
10 Remove the pin retaining fastener from the jib
boom lift cylinder rod-end pivot pin. Do not
remove the pin.
