Brand New 61560020029 Crankshaft for HOWO SHACMAN FAW Weichai Truck Engines' Essential Spare Part

The Crankshaft Assembly (Part No. 61560020029) is a core OE (Original Equipment) component produced by Weichai Power, serving as the central rotating element in diesel engines. It converts the reciprocating linear motion of pistons and connecting rods into rotational torque, which powers the drivetrain and auxiliary systems such as the camshaft, fuel pump, and alternator.

Precision-forged from high-strength alloy steel and treated with advanced surface hardening technologies, this crankshaft delivers exceptional durability, fatigue resistance, and dynamic balance under continuous heavy-load operation. Designed specifically for Weichai’s legendary WD615 series engines, it remains one of the most critical components in China's heavy-duty truck and construction machinery fleets.
