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 hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
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 Support the jib boom lift cylinder with a lifting
device.
6 Remove the pin retaining fastener from the jib
boom lift cylinder barrel-end pivot pin. Use a
soft metal drift to remove the barrel-end pin
and let the cylinder hang down.
Crushing hazard. The platform
and jib boom could become
unbalanced and fall when the jib
boom barrel-end pivot pin is
removed if not properly
supported.
7 Attach a lifting strap from an overhead crane
to the lug on the rod end of the jib boom lift
cylinder.
8 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 may become
unbalanced and fall when it is
removed from the machine if it is
not properly supported by the
overhead crane.
