Service and Repair Manual September 2015Jib Boom Components24 Z-30/20N • Z-30/20N RJ • Z-34/22 • Z-34/22N Part No. 12684983-4 Jib Boom Lift Cylinder3-4Jib Boom Lift CylinderHow to Remove the Jib Boom LiftCylinderNote: Perform this procedure with the boom in thestowed position.Note: When removing a hose assembly or fitting,the O-ring (if equipped) on the fitting and/or hoseend must be replaced. All connections must betorqued to specification during installation. Refer toSpecifications, Hydraulic Hose and Fitting TorqueSpecifications.1 Raise the jib boom slightly and place blocksunder the platform mounting weldment. Thenlower the jib boom until the platform is restingon the blocks just enough to support theplatform.Note: Do not rest the entire weight of the boom onthe blocks.2 Tag, disconnect and plug the jib boom liftcylinder hydraulic hoses. Cap the fittings onthe cylinder.Bodily injury hazard. Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil tosquirt or spray.3 Remove the pin retaining fasteners from thejib boom lift cylinder rod-end pivot pin. Do notremove the pin.4 Use a soft metal drift to tap the rod-end pivotpin half way out and lower one of the levelinglinks to the ground. Tap the pin the otherdirection and lower the opposite leveling link.Do not remove the pin.5 Attach a lifting strap from an overhead craneto the rod end of the jib boom lift cylinder.6 Remove the pin retaining fasteners from thejib boom lift cylinder barrel-end pivot pin. Usea soft metal drift to remove the barrel-endpivot pin.7 Use a soft metal drift to remove the jib boomlift cylinder rod-end pivot pin. Remove the jibboom lift cylinder from the machine.Crushing hazard. The jib boomlift cylinder may becomeunbalanced and fall when it isremoved from the machine if it isnot properly supported by theoverhead crane.
