February 2017 Service ManualOscillating Axle ComponentsPart No. 1259369GT S-80 • S-85 • S-80X 14313-1Oscillating Axle CylindersThe oscillating axle cylinders extend and retractbetween the drive chassis and the axle to maintaina level chassis while driving over uneven terrain.The cylinders are equipped with counterbalancevalves to prevent movement in the event of ahydraulic hose failure.How to Remove an OscillatingAxle CylinderNote: Perform this procedure on a firm, levelsurface 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 hoseend must be replaced. All connections must betorqued to specification during installation. Refer toSpecifications, Hydraulic Hose and Fitting TorqueSpecifications.1 Rotate the turntable until the boom is betweenthe steer tires.2 Remove the fasteners from the drive chassiscover at the steer end. Remove the cover.3 Tag, disconnect and plug the oscillating axlecylinder 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.4 Remove the pin retaining fasteners from therod-end pivot pin. Use a soft metal drift toremove the pin.5 Attach a lifting strap from an overhead craneto the barrel end of the oscillating cylinder.6 Remove the pin retaining fasteners from thebarrel-end pivot pin. Use a soft metal drift toremove the pin.7 Remove the cylinder from the machine.Crushing hazard. The oscillatecylinder may becomeunbalanced and fall whenremoved from the machine if notproperly attached to theoverhead crane.
