Product Introduction

The 612630010055 cylinder liner sleeve is a heavy-duty diesel engine component designed for WEICHAI WP12, WD12, WD615, and related engine platforms used in SINOTRUK HOWO heavy-duty trucks. It forms the inner cylinder wall where piston movement and combustion occur, ensuring stable engine compression, lubrication, and heat dissipation performance.

This cylinder liner sleeve is manufactured from high-strength alloy cast iron material with excellent wear resistance, heat resistance, and anti-corrosion performance. The precision-machined inner surface improves piston movement stability and helps reduce engine wear under continuous heavy-load operating conditions.

The product is widely used in heavy-duty logistics trucks, mining vehicles, dump trucks, and construction transport applications equipped with WEICHAI diesel engines. The cylinder liner is engineered according to OEM specifications to ensure accurate installation compatibility and reliable long-term engine performance.

According to supplier specifications, the 612630010055 liner is commonly compatible with WEICHAI WP12, WD12.420, WD615, WD618, and related heavy truck engine systems.

Each unit is tested for dimensional accuracy, hardness, sealing performance, and durability before shipment to ensure OEM-level quality and long service life.
