The 1003890320 cylinder piston repair kit is designed for Weichai WD615 and WP10 diesel engine platforms, widely used in Chinese heavy-duty trucks such as HOWO, SHACMAN, and FAW applications.

This repair kit provides a complete engine internal restoration solution, helping recover compression efficiency, combustion performance, and overall engine power output after long-term wear or overhaul requirements.

The kit is typically composed of piston assemblies, piston rings, cylinder liners, and piston pins, manufactured under OEM-quality standards to ensure precise fitment, stable sealing performance, and long service life under continuous heavy-load operation.

Designed for long-haul logistics, construction transport, and mining operations, the WD615 / WP10 cylinder piston kit maintains stable performance under extreme temperature and pressure conditions. It helps reduce engine oil consumption, improve fuel efficiency, and restore original engine performance.

Each set is strictly tested before shipment, including dimensional inspection, hardness testing, and durability verification to ensure reliable quality for global aftermarket and fleet maintenance use.
