800160564 XCMG GR2605 motor grader engine

The XCMG GR2605 grader 800160564 engine assembly is the “power heart” of the machine. Manufactured strictly according to XCMG’s original design standards and process specifications, it is equipped with the classic Cummins QSB6.7 power platform, specifically designed for harsh working conditions such as highway construction, airport construction, mining operations, and large-scale earthmoving. As the core power output component of the grader, it directly determines the equipment’s traction capacity, operating efficiency, and fuel economy. It can stably output strong power to support multiple operational needs such as shoveling, slope scraping, bulldozing, and loosening soil. It is a high-quality original factory part for the maintenance, overhaul, or performance restoration of the GR2605 grader’s power system. This engine assembly features an inline six-cylinder, turbocharged, intercooled design with a displacement of 6.7L. It boasts a rated power of 194kW (260hp), a rated speed of 2200r/min, and a maximum torque of 895N・m. With ample power reserves, a towing capacity of ≥99kN, and a climbing ability of 25%, it can easily handle complex terrain and heavy-duty workloads. Equipped with variable power control technology, it intelligently adjusts output power according to different gears (220hp in gears 1-3, 260hp in gears 4-6), optimizing fuel consumption while meeting operational demands. Combined with an intelligent hydraulically driven fan that automatically adjusts speed based on system temperature, it further reduces energy consumption and noise, improving fuel economy by more than 10% compared to ordinary engines. The engine block is made of high-strength cast iron, precision-cast and heat-treated for enhanced impact and deformation resistance. Core moving parts such as pistons and crankshafts are made of wear-resistant alloys, and combined with a high-pressure common rail fuel injection system, ensure uniform atomization and complete combustion, resulting in smooth power output, reduced carbon buildup, and extended service life. It features a comprehensive cooling, lubrication, and protection system with a 50L coolant capacity and a 24L oil capacity, providing high heat dissipation efficiency and adapting to alternating high and low temperature conditions (-30℃ to 55℃). It also includes a fan reversal function for automatic radiator cleaning, reducing maintenance frequency and lowering operating costs.

The product fully complies with the XCMG GR2605 original factory installation standards. The engine mounting bracket, connecting flanges, pipe interfaces, and electrical plugs are precisely matched to the machine, with hole tolerances controlled within ±0.02mm. It exhibits strong compatibility with the transmission and hydraulic system, facilitating easy installation and quick replacement without additional modifications. The machine’s emissions meet the National III emission standard for non-road use. It features low noise and vibration, and its vibration damping and noise reduction design significantly optimizes the cab’s operating environment.
