Hydraulic Main Pump 566-8632 584-0380 for E350GC Excavator

This hydraulic main pump, with part numbers 566-8632 and 584-0380, is the primary hydraulic power unit specially designed for the E350GC excavator hydraulic system. It supplies high-pressure hydraulic oil to drive the boom, arm, bucket, travel, and swing assemblies. Featuring a variable piston structure, precise flow control, wear-resistant alloy materials, and precision machining, it offers direct replacement installation and stable output performance for heavy-duty mining and construction working conditions.

• Internal piston and valve plate wear, causing pressure drop and weak action
• Internal seal failure, resulting in hydraulic oil leakage
• Abnormal noise and vibration during operation
• Servo piston stuck, leading to flow adjustment failure
• Housing crack caused by overload and high pressure
