XCMG XE2000 Excavator Camshaft Gear (Part No. 800169009): Precise Transmission Guarantee for the Valve Train

The XCMG XE2000 mining excavator, with its 192,000kg operating weight, 810kW imported engine, and 10-14m³ bucket capacity, continuously delivers powerful performance in heavy-duty mining operations worldwide. The camshaft gear (part no. 800169009), as a core transmission component of the engine’s valve train, is the “precise commander” controlling the valve opening and closing sequence, directly affecting the engine’s fuel combustion efficiency, power output stability, and overall machine reliability.

This camshaft gear is precision forged from high-strength alloy structural steel. The blank undergoes multiple aging treatments to eliminate internal stress, resulting in excellent fatigue strength and structural rigidity. To meet the stringent requirements of high-frequency, full-load engine operation in mining, the gear teeth undergo a deep carburizing and quenching process, achieving a carburized layer depth of 1.1-1.4mm and a surface hardness of 59-63HRC. The tooth root fillets are strengthened through rolling, effectively resisting contact fatigue and bending stress caused by long-term meshing, preventing fatal failures such as tooth surface spalling and tooth breakage, and ensuring the long-term stable operation of the valve train.

In terms of design, relying on XCMG’s engine dynamics simulation platform, the gear module, tooth ratio, and tooth profile correction parameters have been verified through 2000 hours of bench testing. A high-precision involute tooth profile and edge-modified design are employed, with the meshing clearance with the crankshaft gear strictly controlled within the optimal range of 0.03-0.05mm, and the transmission ratio error less than 0.01%, ensuring that the angular deviation of the camshaft per revolution does not exceed 0.05°. Precise phase positioning design ensures a perfect match between the valve opening angle and lift curve and combustion chamber conditions, achieving optimal control of fuel atomization and air-fuel mixture ratio, improving combustion efficiency by over 3%.

Leveraging XCMG’s intelligent manufacturing system, the entire gear manufacturing process utilizes a digital traceability system. The CNC hobbing machine achieves IT5 precision, with a cumulative pitch error ≤0.02mm and a tooth direction error ≤0.015mm, ensuring smooth transmission. The gear’s inner bore and keyway are ground using a single-clamping grinding process, with a coaxiality error ≤0.01mm, preventing eccentricity and wobbling after assembly. Each gear undergoes 100% magnetic particle testing and tooth surface hardness testing to eliminate internal cracks and machining defects. In actual mining operations, the precise transmission of the camshaft gear directly brings three core benefits: First, by stably controlling valve timing, it ensures more complete fuel combustion under heavy-load climbing and full-bucket digging conditions, reducing fuel consumption by 7-10%; second, it reduces the impact load on the valve train, lowering the wear rate of components such as valves, rocker arms, and tappets, extending the overhaul cycle of the valve train system by more than 40%; and third, it reduces engine operating noise by 3-5 decibels, improving driving comfort while reducing mechanical fatigue damage.

Faced with the complex environment of mines, this gear exhibits excellent adaptability. The tooth surface undergoes special phosphate treatment to improve wear resistance and rust prevention, maintaining stable performance over long periods in dusty and high-humidity environments; the inner bore mating surfaces are precision ground and polished, with a roughness controlled within 0.8μm, ensuring a tight fit with the camshaft and reducing vibration and energy loss during operation. Choosing the XCMG XE2000 excavator camshaft gear (part number 800169009) not only provides you with a high-precision transmission component compatible with the original engine, but also allows you to benefit from XCMG’s global parts service network, including 24-hour technical consultation, fast logistics delivery, and professional installation guidance. Let the precise transmission of this valve train system solidify the power output foundation of your mining equipment, continuously creating production value.
