The genuine XCMG Temperature Sensor with OEM number 800172674 is a high-precision thermal sensing component engineered for XCMG articulated dump trucks, wheel loaders, and heavy off-highway equipment. This sensor provides real-time temperature monitoring of engine coolant, hydraulic oil, and transmission fluid, enabling accurate ECU feedback to prevent overheating, reduce component wear, and maximize uptime in extreme mining and construction environments.
The XCMG temperature sensor 800172674 employs a hermetically sealed NTC thermistor element with laser-trimmed resistance tolerance. This ensures drift-free operation even after 10,000 thermal shock cycles from -40°C to +150°C.
Unlike standard aftermarket sensors, the OEM 800172674 includes a built-in ASIC linearizer, providing a direct 0-5V output that matches XCMG engine control modules without calibration. Field tests confirm ±0.3°C repeatability after 8,000 operating hours in mining haul trucks.
The 800172674 sensor withstands continuous exposure to engine coolant (ethylene glycol), hydraulic oil (ISO VG 46), and transmission fluid without seal degradation. The stainless steel probe resists cavitation erosion and galvanic corrosion.
IP69K rating allows direct high-pressure steam cleaning, eliminating false alarms caused by moisture ingress. This is critical for underground mining applications where sensors are frequently washed down.
OEM 800172674 directly replaces XCMG original sensors on AD45, AD60, AD80, and AD100 dump trucks. It is also retrofitable to older AD30 models using an adapter harness (sold separately).
For wheel loaders (LW700KN, XG958), this sensor monitors transmission sump and hydraulic tank temperatures. Stocking a single part number reduces fleet downtime and simplifies parts management.
Before installing sensor 800172674, clean the mounting boss thread and apply a light coat of anti-seize compound. Torque to 18 N·m ±2 N·m. Do not overtighten; use a crowsfoot wrench to avoid damaging the hex flats.
Connect the Deutsch connector until an audible click confirms full seat. Verify continuity between pins: pin A = signal, pin B = ground. No calibration is required; the sensor is pre-linearized for XCMG ECUs.
After installation, run the engine to operating temperature and compare dash gauge reading with an infrared thermometer. Tolerance within ±2°C is acceptable.
On articulated dump trucks, this sensor monitors engine coolant outlet temperature, preventing head gasket failure and cylinder liner cavitation. It also tracks retarder oil temperature, enabling automatic cooling fan activation.
In hydraulic systems, the 800172674 detects oil overheating before pump or valve damage occurs. The ECU triggers a derate or shutdown if temperature exceeds 115°C, saving thousands in repair costs.
A study of 25 XCMG AD80 trucks over 18 months showed that using OEM sensor 800172674 reduced false engine alarms by 94% compared to generic sensors. Each false alarm previously caused an average of 2.5 hours of unnecessary troubleshooting and downtime.
Accurate temperature feedback prevented three major overheating events that would have resulted in engine rebuilds (~$22,000 each). The total avoided cost exceeded $66,000 across the fleet.
Each XCMG temperature sensor 800172674 undergoes 100% final testing in a thermal bath from -40°C to +150°C, with resistance values recorded at 10°C increments. A unique serial number is laser-marked on the hex, traceable to test certificates.
Counterfeit sensors often use non-automotive grade components that drift after 500 hours. Insist on genuine XCMG packaging with holographic security labels. Only genuine sensors preserve factory warranty and engine protection strategies.
