This Driven Gear for Shacman Delong is a core component of the transmission system. It is forged from high-strength alloy steel, with precisely quenched and ground tooth surfaces, offering high hardness and excellent wear resistance to withstand variable impact loads under heavy-duty conditions. The accurately machined teeth ensure smooth meshing and low noise, reducing impact and premature wear. The internal spline and mounting dimensions are strictly controlled according to original drawings for tight assembly and stable operation. It is suitable for replacing worn, pitted, broken or jump-fault driven gears, restoring normal gear ratio and power output. It is a key transmission part for Shacman Delong maintenance.
