How to Remove the Yoke
and Drive Motor
Note: When removing a hose assembly or fitting,
the O-ring on the fitting and/or hose must be
replaced and then torqued to specification during
installation. Refer to Section 2,
Hydraulic Hose and
Fitting Torque Specifications.
1 Block the non-steer wheels and center a lifting
jack under the drive chassis at the steer end of
the machine.
2 Loosen the wheel lug bolts. Do not remove
them.

6 inches / 5 cm. Place blocks under the chassis
for support.

allow the oil pressure to
dissipate gradually. Do not
allow oil to squirt or spray.

assembly to a lifting jack.

pin.
