Yoke and Hub

How to Remove the Yoke and Hub

The yoke installation utilizes bushings and a thrust
washer that require periodic replacement
depending upon the application. The yoke must be
removed before the torque hub can be removed.
The wheel motor is an integral part of the torque
hub.

1 Remove the cotter pin, then the clevis pin from

both the steering cylinder and the tie rod
weldment.

2 Disconnect the hydraulic hoses from the wheel

motor and plug them. Cap the wheel motor
hydraulic fittings.

Bodily injury hazard. Spraying
hydraulic oil can perforate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to squirt
or spray.

3 Loosen the wheel lug nuts. Do not remove

them.

4 Block the non-steering wheels, and then center

a lifting jack under the steering axle.

5 Raise the machine 6 inches (15cm) and place

blocks under the chassis.

6 Remove the lug nuts, then the tire and wheel

assembly.

7 Remove the pin retainer from the king pin.

8 Place a block between the oscillate cylinder

lock-out wedge and the chassis on the same
side as the yoke/torque hub being serviced.
