SSY004928745 Main pump front diaphragm Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004928745 main pump front baffle is a core protective component of SANY’s original hydraulic system. It is specifically designed for assembly at the front end of the main pump, protecting the pump body, regulating the cooling airflow, and preventing the intrusion of sand, dust, and oil. It also isolates the engine compartment from high temperatures and reduces operating noise. It effectively improves issues such as dust accumulation and blockage in the main pump, poor heat dissipation, component wear, and oil line contamination. The original factory hole dimensions are precise, allowing for direct replacement without modification. It is suitable for hydraulic system maintenance, complete machine assembly, and bulk stocking.
This product, as a key protective component of the main pump assembly, is made of high-strength sheet metal through one-piece stamping, ensuring sufficient rigidity and impact resistance without deformation. Utilizing a scientifically designed flow-guiding structure, it optimizes heat dissipation for the main pump, preventing hydraulic efficiency degradation caused by heat buildup. Suitable for harsh working conditions such as dusty, high-temperature, high-vibration, and oily environments, it is resistant to rust and deformation even after long-term operation, providing stable protection for the main pump and surrounding hydraulic components, reducing hydraulic failures and maintenance costs.

【Core Technical Parameters】

— Product Model: SSY004928745

— Compatible Models: Compatible with all Sany excavators, loaders, concrete pumps and other construction machinery. Matches the original main pump front mounting position and can directly replace old, deformed, rusted and damaged partitions.
— Main material: Thickened high-strength cold-rolled steel plate integrally formed, with high rigidity, impact resistance and wear resistance, can withstand sand and gravel impact and external force collision, and is suitable for long-term high-intensity outdoor operation.
— Operating temperature range: -45℃~+125℃, wide temperature adaptability, resistant to high temperature in the cabin and alternating outdoor temperature differences, maintaining structural stability without deformation or softening throughout the process.
— Structural design: Precise molded by the original factory, fitting the installation curvature of the main pump and the air duct layout, with built-in reinforced structure to improve strength, and reserved standard fixing and heat dissipation holes to adapt to the original factory assembly standards.
— Protective performance: Dedicated isolation and protection structure, highly efficient dustproof, oil-blocking, heat insulation and noise reduction, effectively blocking dust, oil and mud from entering the main pump area, protecting the hydraulic core components from corrosion and wear.
— Surface treatment: Electrophoretic anti-rust + weather-resistant spray coating dual anti-corrosion process, resistant to salt spray, anti-aging, not easy to peel off, and long-term resistance to high temperature oil stains in the cabin and outdoor sun corrosion.
— Dimensional accuracy: Original IT7 grade precision tolerance, the contour, hole position and mating surface are completely matched with the original main pump assembly, 1:1 non-destructive adaptation, no grinding or modification required.
— Installation method: Standard bolt fixing installation, compatible with original bracket fixing points, simple and convenient disassembly and assembly, supports repeated maintenance, and will not loosen or shift during high-frequency vibration operation.
— Adaptability to working conditions: Suitable for harsh construction scenarios such as mines, infrastructure, and highways, it is impact-resistant, vibration-resistant, and fatigue-resistant, effectively avoiding problems such as partition deformation, air duct blockage, and protection failure.
— Service life: ≥6 years under standard operating conditions, ≥4 years under harsh high-frequency operating conditions. Excellent anti-corrosion and anti-aging performance, effectively reducing the cost of main pump failure and hydraulic system maintenance.

Suitable for all-weather construction scenarios of engineering machinery, the Sany SSY004928745 original main pump front baffle has protection, heat dissipation, noise reduction and dirt blocking performance, ensuring the stable operation of the main pump and hydraulic system in all aspects, reducing failures caused by high temperature, dust accumulation and wear. It is a high-quality original part for hydraulic maintenance and replacement of Sany equipment, complete machine matching and bulk purchase.
