This is a speed sensor that monitors the rotational speed of components within the excavator's drivetrain or hydraulic system. It is manufactured to precise specifications to ensure accurate signal transmission, unlike a worn sensor that provides erratic or no data. Operators may observe erratic engine RPM readings, transmission shifting issues, or loss of hydraulic power when this sensor fails.
Always verify with serial number before ordering.

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing speed sensor may initially cause intermittent false readings, leading to erratic performance. If left unaddressed, the sensor can fail completely, resulting in a loss of critical operational data and potential equipment shutdown. Continued operation with a faulty sensor can lead to drivetrain or hydraulic system damage.
Clean the sensor mounting port thoroughly before installation to ensure a proper seal and accurate readings. Avoid using excessive force when threading the sensor into its housing to prevent cross-threading.
Inspect the wiring harness and connector for damage or corrosion when replacing the speed sensor.
