The 803590829 Combination Gauge is a genuine OEM instrument cluster manufactured by XCMG for heavy-duty motor graders and construction machinery. This multifunction display integrates speedometer, tachometer, fuel level, coolant temperature, and warning indicators in a single rugged housing.
Designed to withstand extreme vibration, dust, and moisture, the 803590829 gauge features a sealed polycarbonate lens and IP65-rated rear connectors. It directly replaces worn or failed combination gauges on XCMG GR series graders, restoring accurate machine monitoring.
Each unit is calibrated to XCMG factory specifications, ensuring precise readings for engine hours, ground speed, hydraulic oil temperature, and electrical system voltage. Plug-and-play installation with original connector saves downtime.

The XCMG 803590829 Combination Gauge provides operators with real-time critical data. The large analog dials are backlit for excellent visibility in low light or night operations. An integrated LCD screen displays engine hours, odometer, trip distance, and diagnostic trouble codes.
This gauge receives data from the engine ECU, transmission controller, and various sensors via the CAN bus (J1939 protocol). It eliminates the need for separate warning lamps by consolidating all alerts: high coolant temperature, low oil pressure, brake air pressure, alternator charge, and transmission filter restriction.
Every 803590829 unit is calibrated using XCMG’s proprietary software to match the specific grader model. The speedometer accuracy is ±2%, and the tachometer ±1.5%. Field tests confirm consistent performance even after thousands of operating hours.
Older XCMG motor graders often suffer from faded dials, stuck needles, or non-functional LCD segments. The 803590829 gauge is a direct physical and electrical replacement. Simply remove the dashboard bezel, unplug the old harness, and install the new combination gauge.
No reprogramming is required because the gauge automatically learns the vehicle configuration from the CAN bus. However, the odometer value can be pre-set upon request to match the machine’s actual hours (contact support for details). Installation takes less than 30 minutes.
The gauge housing uses the same mounting points and screw pattern as the original. All warning icons are printed on the face in universal ISO symbols, making them understandable for operators of any language.
Inside the 803590829 Combination Gauge, automotive-grade stepper motors drive the needles with high torque, eliminating needle flutter or sticking. The LCD is rated for -40°C operation and features a defroster heater to prevent fogging in humid environments.
The rear circuit board is conformal coated to resist corrosion from salt spray, condensation, and dust. All input circuits are protected against overvoltage, reverse polarity, and load dump (up to 100V for 200ms). This ruggedness is essential for mining and road construction sites.
XCMG tests each 803590829 gauge for 168 hours of thermal cycling, 96 hours of humidity (95% RH at 65°C), and 48 hours of salt fog (ASTM B117). The front lens is made of hardened polycarbonate with an anti-scratch coating, resisting impacts from rocks or tools.
The combination gauge includes 18 LED warning lamps: parking brake, engine check, transmission fault, hydraulic oil filter clog, air filter restriction, water-in-fuel, glow plug preheat, low battery voltage, high beam, turn signals, and more.
Unlike aftermarket clusters, the 803590829 displays CAN-based warnings exactly as the XCMG factory intended. For example, the transmission overheat warning flashes at 115°C and becomes steady at 120°C, with a simultaneous audible buzzer output.
The gauge also provides a service reminder based on engine hours (programmable intervals). This helps fleet managers schedule preventive maintenance, reducing unexpected breakdowns.
Counterfeit combination gauges often have incorrect sensor scaling, poor backlight uniformity, and early LCD failure. The genuine XCMG part guarantees accurate readings, long LED life (50,000 hours), and full compatibility with your grader’s CAN network.
XCMG provides a 12‑month unlimited-hour warranty against defects. Each gauge comes in original XCMG packaging with a serial number for traceability. The 803590829 supersedes older numbers 803590612, 803590745, and 803590801.
Using genuine parts preserves your equipment’s resale value and operator confidence. Don’t risk misinterpreted warnings or inaccurate speed readings — choose the OEM solution.
