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.

2

turntable cover.

Tag, disconnect the hydraulic hoses from the
turntable rotation motor. Cap the fittings on the

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.

other suitable lifting device to the lifting eye on
the turntable rotation assembly.
5
Remove the drive hub mounting bolts and
remove the turntable rotation assembly from
the machine.
6
Repeat steps 3 through 5 for the other
turntable rotation assembly.
Tip-over hazard. If the turntable
rotation lock pin is not properly
installed, machine stability is
compromised and the machine
could tip over when the drive hub
is removed from the machine,
which could result in death or
serious injury.
Crushing hazard. The drive hub
could become unbalanced and
fall if not properly supported by an
overhead crane or lifting device
when removed from the machine.
Note: When installing a turntable rotation assembly,
the rotation gear backlash must be adjusted. Refer
to Repair Procedure,
