How to Remove a Turntable
Rotation Assembly
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications, Hydraulic Hose and Fitting Torque
Specifications.
Note: Perform this procedure with the primary
boom between the circle-end tires and with the
machine on a firm, level surface.
1 Secure the turntable from rotating with the
turntable rotation lock pin.
2 Remove the ground controls side fixed
turntable cover.
3 Tag, disconnect the hydraulic hoses from the
turntable rotation motor. Cap the fittings on the
motor.
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.
4 Attach a lifting strap from an overhead crane
or other suitable lifting device to the lifting eye
on the turntable rotation assembly.

could become unbalanced and
fall if not properly supported by
an overhead crane or lifting
device when removed from the
