803502420 oil temperature sensor for XCMG ZL50G/ZL50GL Wheel Loader

product parameters

Product Name: Oil Temperature Sensor
Part No.: 803502420
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Temperature sensing accessory
Installation Position: Transmission/torque converter oil temperature measurement point
Function: Oil temperature detection and signal output

Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with heavy loads and continuous operation. It is a key sensing accessory for ensuring controllable transmission oil temperature and preventing overheating damage.

▪ Direct oil temperature monitoring to prevent transmission overheating
Real-time oil temperature detection and signal output help the driver identify abnormal oil temperature promptly and avoid oil degradation and transmission component damage from overheating.

▪ Mounting matches original measurement point for easy replacement
Designed to the original oil temperature measurement point interface, requiring no mounting structure modification during replacement and shortening on-site repair time.

▪ Can be stocked with other sensors for the same model
Can be stocked together with water temperature sensors, air pressure sensors, fuel sensors, and related parts for the same model, facilitating complete procurement during sensor system maintenance.

FAQ 

Q：Is abnormal oil temperature display always caused by the sensor?
A: Not necessarily. Check whether the sensor connector is loose, the wiring has open or short circuits, and the instrument itself is normal first. Inspect the sensor for failure after confirming peripheral circuits are normal.

Q：When does an oil temperature sensor need replacement?
A: Replace when the oil temperature reading stays fixed, deviates significantly from actual temperature, instrument alarms occur, the sensor housing leaks oil, or terminals are corroded or broken.

Q：What to note during oil temperature sensor installation?
A: Confirm the sensor thread specification matches the measurement point interface. Clean around the measurement point before installation to prevent contaminants from entering the oil circuit. Tighten to specified torque to avoid thread damage from over-tightening or oil leakage from under-tightening. Align connectors during wiring.

Q：How to maintain the oil temperature sensor daily?
A: Regularly check sensor connectors for looseness and wiring for wear. Observe whether oil temperature readings change normally. Check the sensor measurement point for oil seepage during transmission maintenance.
