XCMG XE2000 Excavator Engine Crankshaft (Part No. 800169153): The Core Drive Shaft for Heavy-Duty Power

In global heavy-duty mining operations, the XCMG XE2000 mining excavator, with its robust configuration of a 192,000kg operating weight, an 810kW imported engine, and a large bucket capacity of 10-14m³, has become a core piece of equipment for efficient mining. The engine crankshaft (part no. 800169153), as the “central nervous system” that converts the reciprocating motion of the piston into rotational power, is a core component ensuring the machine’s powerful power output and directly determines the equipment’s operational stability under extreme working conditions.

This engine crankshaft is made of high-strength alloy structural steel through integral forging, possessing excellent fatigue resistance and load-bearing capacity. Addressing the immense torque demands of the XE2000 engine’s high power output, the crankshaft body undergoes precise mechanical design. It can evenly withstand cyclic impact loads, effectively resisting stress fatigue caused by long-term heavy-load operation, preventing fatal failures such as breakage and deformation, and providing solid support for the engine’s continuous and stable power output.

In terms of design, it is based on specialized research and development of engine combustion parameters and power characteristics. The crankshaft journal diameter, crank arm thickness, and balance weight layout have undergone multiple rounds of dynamic simulation optimization. Through precise counterweight design and dynamic balancing adjustments, centrifugal force fluctuations during high-speed operation are significantly reduced, minimizing engine vibration amplitude and ensuring stable operation across the entire operating range from idle to full load, improving the comfort and safety of equipment operation.

Relying on XCMG’s advanced manufacturing processes, this crankshaft undergoes rigorous precision machining and strengthening treatment. The surfaces of the main journals and connecting rod journals are processed using ultra-precision grinding, combined with high-frequency quenching technology to form a hard and wear-resistant surface layer with a hardness reaching [specific value] HRC or higher, while maintaining good core toughness, significantly improving wear resistance and impact resistance. Every crankshaft undergoes 100% magnetic particle inspection and dimensional accuracy testing to completely eliminate internal defects and machining errors, ensuring reliability after installation.

The crankshaft’s performance directly affects the engine’s power output and fuel efficiency. Through a highly efficient power conversion mechanism, it precisely converts the heat energy generated by fuel combustion into mechanical energy, ensuring the XE2000 excavator outputs strong torque in heavy-duty excavation and hill-climbing operations. Optimized journal lubrication design reduces friction loss, helping the engine achieve lower fuel consumption and reducing operating costs in mining operations. Simultaneously, stable power transmission reduces impact on related components such as the gearbox and hydraulic pump, extending the overall machine’s service life.

Choosing the XCMG XE2000 excavator engine crankshaft (part number 800169153) not only provides a precisely matched, high-performance core power component, but also leverages XCMG’s global service network to enjoy professional technical support and rapid parts replenishment. Let this core drive shaft, a heavy-duty power source, inject sustained power into your mining equipment, ensuring uninterrupted high-efficiency production.
