Truck Spare Parts YC6G Repair Kit Engine Crankshaft G6000-1005001D-P3 for YUTONG Bus Parts

The G6000-1005001D-P3 Engine Crankshaft Assembly is an original equipment (OE) forged alloy steel crankshaft designed for use with Yuchai YC6A and YC6J series 6-cylinder diesel engines. As the central power-transmitting component of the engine, it converts the reciprocating motion of pistons into rotational torque—making it one of the most critical and heavily stressed components in any internal combustion engine.

Manufactured from high-strength forged alloy steel, this crankshaft offers superior fatigue resistance and torsional rigidity compared to cast iron alternatives. Key journals—including main and connecting rod journals—are precision ground and treated with fillet rolling and high-frequency induction hardening to enhance surface hardness (HRC ≥58), wear resistance, and long-term durability under continuous load.

The "P3" designation indicates its advanced manufacturing platform and high dynamic balance grade, ensuring minimal vibration at high RPMs—critical for smooth operation in luxury coaches, heavy-duty trucks, and industrial machinery.

Used across Yutong, King Long, Higer buses, and various commercial vehicles and construction equipment, this crankshaft must be installed with strict adherence to cleanliness, lubrication, and torque specifications to ensure maximum reliability.
