As a dedicated component for the QSB6.7 engine, this piston assembly is suitable for excavators, loaders, generator sets, and other equipment equipped with this engine model.
Under heavy-duty conditions, its aluminum alloy material allows for rapid heat dissipation, preventing localized overheating and cylinder scoring. In scenarios with frequent start-stop cycles, the piston pin's fatigue resistance reduces the risk of fracture.
During installation, it is crucial to strictly adhere to cold-state clearance standards (e.g., piston-cylinder wall clearance controlled at 0.12-0.15mm) and use a specialized tool to press the piston pin in place to avoid deformation.
