April 2016 Service ManualPlatform ComponentsPart No. 139378 Z-30/20N • Z-30/20N RJ • Z-34/22 • Z-34/22N 492-1Platform Leveling Slave CylinderThe slave cylinder and the rotator pivot are the twoprimary supports for the platform. The slavecylinder keeps the platform level through the entirerange of boom motion. It operates in aclosed-circuit hydraulic loop with the mastercylinder. The slave cylinder is equipped withcounterbalance valves to prevent movement in theevent of a hydraulic line failure.How to Remove the PlatformLeveling Slave CylinderNote: Before cylinder removal is considered, bleedthe slave cylinder to be sure there is no air in theclosed loop.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 Extend the boom until the slave cylinderbarrel-end pivot pin is accessible.2 Raise the boom slightly and place blocksunder the platform for support. Lower theboom until the platform is resting on theblocks.3 Tag and disconnect the hydraulic hoses to theslave cylinder at the union and connect themtogether with a connector. Cap the fittings onthe cylinder hoses.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.4 Remove the external snap rings from therod-end pivot pin. Do not remove the pin.5 Remove the external snap rings from thebarrel-end pivot pin.6 Place a block of wood under the barrel of theslave cylinder for support.7 Use a soft metal drift to remove the rod-endpivot pin.Crushing hazard. The platformcould fall if not properlysupported.8 Use a soft metal drift to remove the barrel-endpivot pin.9 Carefully pull the cylinder with hydraulic hosesout of the boom.How to Bleed the Slave Cylinder1 Raise the jib boom to a horizontal position.2 Move the platform level toggle switch up anddown through two platform leveling cycles toremove any air that might be in the system.
