Traction Speed Sensor
Removal (Fig. 162)
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Locate speed sensor on right side wheel motor. Dis-
connect speed sensor from machine wire harness.
3. Loosen lock nut and remove speed sensor from
wheel motor.
4. Locate and discard sensor O−ring.
5. Plug sensor port to prevent hydraulic system con-
tamination.
Installation (Fig. 162)
1. Thread lock nut fully onto speed sensor threads.
2. Center a wheel motor piston in the center of the sen-
sor port (see Sensor Port View in Fig. 163). Use a suit-
able tool to feel when the center of a motor piston is in
the center of the sensor port.
3. Lubricate new O-ring and thread sensor into port un-
til sensor lightly contacts piston.
4. Turn sensor out (counter-clockwise) until angle be-
tween sensor orientation grooves and motor center−line
is between 90 and 93 degrees (see Sensor Installation
View in Fig. 163), then back out sensor one (1) full turn.

5. Hold sensor in position and rotate motor output shaft
one complete revolution to make sure it rotates freely,
then tighten sensor lock nut from 75 to 125 in-lb (8.5 to
