Traction Speed Sensor

Removal (Fig. 45)
NOTE: It is recommended that this procedure be done
with the wheel motor removed from the machine.
1. Remove right side wheel motor from machine (see
Wheel Motor Removal in Service and Repair Section of
Chapter 4 – Hydraulic System).
2. Loosen lock nut and remove speed sensor from
wheel motor.
Installation (Fig. 45)
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. 46). NOTE: If the
motor is on the machine, use a suitable tool to feel when
a motor piston is in the center of the sensor port.
3. Lubricate O-ring and install onto sensor threads.
4. Thread sensor into port until sensor contacts piston.
Rotate motor output shaft one complete revolution to
make sure it rotates freely.
5. Turn sensor out (counter-clockwise) until angle be-
