800166985 crankshaft counter weight block XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Crankshaft Balance Block (Part No. 800166985): The Core of Power Stability

The XCMG XE2000 mining excavator, with its 192,000kg operating weight, 810kW imported engine, and 10-14m³ large bucket capacity, demonstrates powerful performance in heavy-duty mining operations worldwide. The crankshaft balance block (part no. 800166985), as a key component of the crankshaft system, is a core component ensuring the stability of the engine at high speeds, directly affecting the smoothness and reliability of the overall machine’s power output.

This crankshaft balance block is precision-cast from high-density alloy cast iron, possessing precise weight distribution and structural strength. Addressing the centrifugal force generated by the high-speed rotation of the XE2000 engine crankshaft, the balance block, through a scientifically designed mass distribution, effectively counteracts the unbalanced inertial force during crankshaft operation, reducing engine vibration amplitude and preventing accelerated component wear or structural fatigue caused by severe vibration, providing a fundamental guarantee for the long-term stable operation of the engine. In terms of design, it is based on specialized research and development of crankshaft dynamic parameters. The external dimensions, installation position, and weight parameters of the balance weight have been precisely calculated and dynamically simulated. Through perfect matching with the crankshaft body, it forms an optimized balancing system that can specifically balance the inertial torque under different operating conditions, significantly reducing vibration and noise during engine idling and high-load operation, improving the smoothness of equipment operation, and reducing operator fatigue.

Relying on XCMG’s advanced manufacturing process, the balance weight undergoes rigorous weight accuracy testing and dynamic balancing verification. The surface is precision machined to ensure the fit and installation accuracy with the crankshaft, avoiding the impact of assembly errors on the balancing effect. Non-destructive testing technology is used during the casting process to effectively eliminate internal porosity, cracks, and other quality hazards, ensuring structural stability under long-term high-frequency vibration environments.

The performance of the crankshaft balance weight is directly related to the engine’s service life and operating efficiency. By reducing the impact of vibration on core components such as the crankshaft and bearings, it reduces the wear rate and extends the engine’s overhaul cycle; stable operation also allows for more complete fuel combustion, helping to improve engine fuel economy and reduce energy costs in mining operations. Meanwhile, reduced vibration transmission to the entire machine structure minimizes interference with the hydraulic system and electrical components, improving overall equipment reliability.

Choosing the XCMG XE2000 excavator crankshaft balance block (part number 800166985) not only provides you with a precisely matched and reliable balancing component, but also allows you to leverage XCMG’s global service network to enjoy professional technical support and timely spare parts supply. Let this stable balancing core build a solid power balance defense for your mining equipment, contributing to efficient and stable production.
