Product Description: Sinotruk HOWO MT07 05 Piston (Part No. 082V02500-0710)

Upgrade your Sinotruk HOWO truck’s engine performance with this high-quality MT07 05 Piston (082V02500-0710) — an OEM-equivalent replacement designed for durability, thermal efficiency, and smooth combustion in heavy-duty diesel engines.

This piston is precision-engineered for the Sinotruk WD615 series engine, commonly used in HOWO A7, T5G, T7H, Sitrak C7H/C9H, and other CNHTC commercial vehicles. Made from high-strength forged aluminum alloy, it delivers excellent resistance to thermal expansion, fatigue stress, and mechanical wear under continuous load conditions.

Each piston features:

• Precision-machined crown profile for optimal swirl and compression ratio (17.5:1)

• Three-ring design: Top chrome-coated ring, second oil-control ring, and dual rail scraper bottom ring

• Skirt coated with anti-friction polymer to reduce cylinder wall scuffing

• Full-floating wrist pin with bronze bushing for smooth articulation

Pre-balanced and individually tested for dimensional accuracy, this piston ensures minimal vibration, reduced oil consumption, and extended engine life — ideal for fleet maintenance, engine rebuilds, and long-haul operations.

Whether you're replacing a damaged piston or overhauling an entire engine block, this genuine-specification component offers reliable compatibility and long-term performance.
