SSY009740942 Main Pump Rear Door Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY009740942 main pump rear door assembly is a genuine SANY hydraulic protection accessory, compatible with all SANY construction machinery, including excavators, loaders, and pump trucks. Installed at the rear of the main pump compartment, it encloses the open areas of the machine body, shielding the main pump, oil pipelines, valves, and other precision components. This effectively prevents sand and gravel splashes, mud and water erosion, and dust accumulation, reducing pipeline wear, joint corrosion, and component impacts, ensuring proper heat dissipation in the pump compartment, and maintaining a neat and organized machine appearance.
This product is made of high-strength protective sheet metal in one piece, with a robust structure, strong resistance to bending and impact, and suitable for heavy-duty and harsh working conditions such as mining, infrastructure construction, and earthmoving. During field operations, exposed pump compartments are prone to dust and mud accumulation, clogging air ducts and accelerating the aging of hydraulic components. Ordinary side doors are prone to cracking, rusting, and poor fit, causing protective failure and leading to malfunctions such as main pump overheating and pipeline leaks. This product features precise original factory molding and standard hole positions, allowing for non-destructive replacement of old assemblies. It is suitable for routine maintenance, fault repair, and bulk stocking, effectively reducing hydraulic failures and saving on operation and maintenance costs.
