Section 4 • Repair ProceduresPart No. 122985 S-80 • S-85 • S-80X 4 - 73February 2012Oscillating Axle Components14-1Oscillate 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 Oscillate AxleCylinderNote: Perform this procedure on firm, level surfacewith the boom in the stowed position.Note: When removing a hose assembly or fitting,the O-ring (if equipped) on the fitting and/or thehose end must be replaced. All connections mustbe torqued to specification during installation.Refer to Section 2,Hydraulic Hose and FittingTorque Specifications.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 on thecylinder.Bodily injury hazard. Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil to squirtor 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 crane tothe 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 could become unbalancedand fall if not properly attached tothe overhead crane whenremoved from the machine.
