XCMG XE2000 Excavator Engine Connecting Rod (Part No. 800168935): The Heavy-Duty Bearing Core of Power Transmission

In heavy-duty mining operations worldwide, 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, continuously delivers powerful output. The engine connecting rod (part no. 800168935), as a key transmission component connecting the piston and crankshaft, is the “bridge” that converts the reciprocating motion of the piston into the rotational power of the crankshaft, directly determining the efficiency and reliability of engine power transmission.

This engine connecting rod is made of high-strength alloy structural steel through integral forging. The blank undergoes multiple isothermal normalizing treatments to eliminate forging stress, possessing excellent tensile strength and impact toughness. To address the immense power output of the XE2000 engine, reaching up to 810kW, the connecting rod body employs a variable cross-section I-beam structure design. This reduces weight while increasing load-bearing capacity by over 30%, enabling it to withstand cyclic impact loads up to [specific value] kN. This effectively resists fatigue deformation caused by long-term heavy-load operation, preventing fatal failures such as breakage.

In terms of design, relying on XCMG’s engine dynamics simulation platform, parameters such as the connecting rod length, small end bore diameter, and large end bearing clearance underwent 1500 hours of extreme working condition simulation verification. The large end features a beveled design and is secured with high-strength bolts, ensuring connection stability during high-speed crankshaft rotation. The small end is lined with a high-precision bronze bushing, forming a highly efficient sliding friction pair with the piston pin. Combined with a forced lubrication channel design, this reduces the coefficient of friction by over 15%, minimizing power transmission losses.

Thanks to XCMG’s precision manufacturing processes, this connecting rod undergoes rigorous processing and testing procedures. The connecting rod body is machined in a single setup using a CNC machining center, with the parallelism error between the large and small end holes controlled within 0.02mm/m to ensure precise motion trajectory. The surface undergoes shot blasting for enhanced fatigue strength, and the rounded corners in key areas are rolled to effectively disperse stress concentration. Each connecting rod undergoes 100% magnetic particle testing, ultrasonic testing, and weighing and grouping, with weight deviation controlled within 5g to ensure crankshaft balance.

In actual mining operations, the high performance of the connecting rod directly brings multiple core benefits: First, through precise power transmission, it efficiently converts the piston’s explosive force into crankshaft rotational power, enabling the engine to output stronger torque during heavy-duty excavation, increasing operating efficiency by 8-12%; second, its excellent structural stability reduces abnormal wear between the piston and cylinder liner, extending engine overhaul cycles by more than 40%; third, its lightweight design combined with high-precision dynamic balancing reduces crankshaft load and vibration, contributing to a 5-8% reduction in engine fuel consumption. Choosing the XCMG XE2000 excavator engine connecting rod (part number 800168935) not only provides you with a high-quality transmission component compatible with the original engine, but also allows you to enjoy professional support from XCMG’s global service network, including technical parameter consultation, rapid parts replenishment, and installation guidance. Let this heavy-duty load-bearing core of power transmission solidify the power transmission link for your mining equipment engine, ensuring continuous and efficient production.
