High-Quality Weichai 612600013589R Flywheel Housing for Weichai Engines — Shacman, Sinotruk, And HOWO Truck Spare Parts

The 612600013589R is a critical structural component known as the Flywheel Housing (or Flywheel Crankcase) for Weichai (WP10/WP12) heavy-duty diesel engines. This component serves as the primary interface between the engine block and the transmission, providing structural support for the transmission assembly while protecting the flywheel and clutch system from external contaminants.

Manufactured from high-strength cast iron, this housing is designed to withstand high torque loads and engine vibrations. It is widely compatible with major Chinese heavy-duty truck brands, including SHACMAN (Delong X3000/F3000) and Sinotruk (HOWO A7/T7H). The suffix "R" often indicates a specific revision or batch compatible with Euro 5 emission standards. Precision machining ensures proper alignment for the crankshaft rear oil seal and transmission input shaft, preventing leaks and vibration issues.
