On SJC equipped loaders, the speed sensor [Figure 60-80-1] is used by the loader’s controllers to sense if the drive motor is rotating. The end of the sensor is magnetic and counts the magnetic pulses as a rotating disc, attached to the motor carrier shaft, rotates by the sensor end.
The speed sensor is sealed with an O-ring (Item 1) [Figure 60-80-1] to keep hydraulic oil inside the motor carrier and dirt out.
