Jib Boom Lift Cylinder
How to Remove the Jib Boom
Lift Cylinder
Note: Perform this procedure with the boom in the
stowed position.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or the
hose end must be replaced. All connections must
be torqued to specification during installation.
Refer to Section 2,
Hydraulic Hose and Fitting
Torque Specifications.
1 Raise the jib boom slightly and place blocks
under the platform mounting weldment. Then
lower the jib boom until the platform is resting
on the blocks just enough to support the
platform.
Note: Do not rest the entire weight of the boom on
the blocks.
2 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.
3 Remove the pin retaining fasteners from the jib
boom lift cylinder rod-end pivot pin. Do not
remove the pin.
4 Use a soft metal drift to tap the jib boom lift
cylinder rod-end pivot pin half way out. Then
lower one of the leveling arms to the ground.
Tap the pin the other direction and lower the
opposite leveling arm. Do not remove the pin.
5 Attach a lifting strap from an overhead crane to
the lug at the rod end of the jib boom lift
cylinder.
6 Remove the pin retaining fastener from the jib
boom lift cylinder barrel-end pivot pin. Use a
soft metal drift to remove the pin.
7 Use a soft metal drift to remove the jib boom lift
cylinder rod-end pin. Remove the cylinder from
the machine.
Crushing hazard. The jib boom lift
cylinder could become unbalanced
and fall if not properly supported
when removed from the machine.
