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.
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
attached to the overhead crane.
