SSY009741499 Main pump side door assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY009741499 main pump side door assembly is a dedicated protective assembly for Sany’s original hydraulic main pumps. It integrates a door panel, sealing structure, and mounting base for sealing and protecting the main pump compartment, core precision components such as the hydraulic main pump, pipelines, and valve groups, isolating them from impurities and heat sources. It improves issues such as poor side door sealing, water and dust ingress, deformation and loosening, poor heat dissipation, and component wear, stabilizing the hydraulic system’s operating conditions. With precise original factory hole positions, no modification is required; it can directly replace older assemblies and is suitable for equipment maintenance, new machine installation, and bulk stocking.
This product is a core protective assembly for the hydraulic system of engineering machinery. It is made of high-strength alloy steel plate, integrally stamped and welded, providing ample rigidity, impact resistance, and resistance to deformation. It can withstand impacts from gravel and high-frequency vibrations from the equipment. Equipped with a specialized sealing structure, it effectively prevents dust, rainwater, mud, and oil from entering the pump chamber. Its well-organized cooling airflow ensures stable heat dissipation of the main pump and avoids high-temperature pressure buildup. Suitable for harsh working conditions such as mining, infrastructure construction, and dusty, humid environments, it is resistant to rust and deformation even after long-term operation, effectively protecting core hydraulic components and reducing hydraulic failures and maintenance costs.
