Shacman Howo Truck Parts Pneumatic Cylinder Piston And Kits for Weichai Engine Spare Parts Cylinder Piston Kit 612600030034A

The 612600030034A is a high-performance Engine Piston Assembly designed specifically for Weichai (WP10) series diesel engines. As a core component of the combustion chamber, this piston converts the energy generated by fuel combustion into mechanical power to drive the vehicle.

Manufactured from high-strength aluminum alloy, it features a heat-resistant insert ring and internal cooling oil channels to withstand the extreme temperatures and pressures of heavy-duty operation. This component is widely compatible with major Chinese heavy-duty truck brands, including SHACMAN, SINOTruk (HOWO), and JAC, as well as various construction machinery. It is optimized for Euro II/III emission standard engines, ensuring stable combustion and reliable power output.
