as part of the wheel drive assembly or they can be removed
separately through the bottom of the frame while leaving
the drive hub bolted to the axle.

Use a jack to lift the frame enough so the tire and wheel
assembly is off the ground. Place blocking strong
enough to support the weight of the machine under the
frame and remove the jack.
NOTE:
The foam-filled tire & wheel assembly weighs approxi-
mately 867 lbs. (393 kg). The solid tire & wheel assembly
weighs approximately 960 lbs. (435 kg).
2.
Remove hardware securing wheel and remove tire and
wheel assembly. Using suitable lifting device lift the tire
and wheel assembly and place in a suitable area.
3.
Tag and disconnect the hydraulic lines running to the
drive motor. Cap or plug all openings to ensure no dirt
enters the hydraulic system.
NOTE:
The drive hub and drive motor assembly weighs approxi-
mately 267 lbs. (121 kg).
4.
Use a supporting device capable of handling the weight
of the drive hub and drive motor, and unbolt the drive
hub from the frame. Remove the entire assembly from
the machine.

drive motor to the drive hub and remove the drive
motor. Remove and discard the brake gasket between
the drive motor and drive hub.

secure the drive hub and drive motor, and torque to
178 ft. lbs. (241 Nm).

Place the drive hub flange against the mounting flange
on the axle and fasten it in place with the bolts and
washers. Torque the bolts to 180 ft. lbs. (244 Nm).
