Troubleshooting Procedure for the Engine Speed Sensor on Small Track-Type Tractors {1907}
- Track-Type Tractor:
- D3G (S/N: JMH1-UP)
- D4G (S/N: FDC1-UP; HYD1-UP; TLX1-UP)
- D5G (S/N: WGB1-UP; RKG1-UP)
Issues have been reported with the 189-5746 Speed Sensor Gp in the field. The debris at the tip of the sensor can affect the signal from the sensor. The debris is caused by contact with the starter gear and the flywheel gear. The debris can accumulate at the tip of the sensor.
Remove the 189-5746 Speed Sensor Gp from the engine and clean the tip of the sensor. The sensor should be checked after 1,000 hours of operation. Reinstall the sensor. Check the connection of the connector and the harness for any damage if the problem still exists. If damage is found then replace the speed sensor with a new speed sensor.
