Swing Motor Assembly 542-7625 587-4961 for E374 E395GC Excavator

This swing motor assembly, with part numbers 542-7625 and 587-4961, is the hydraulic drive unit specially designed for the E374 and E395GC excavator swing system. It converts hydraulic pressure into torque to drive the rotation of the upper structure. Featuring a high-torque piston structure, precise sealing design, 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 swing torque
• Internal seal failure resulting in hydraulic oil leakage
• Abnormal noise and vibration during swing operation
• Brake piston stuck, leading to swing brake failure
• Housing crack caused by overload and impact load

• Confirm the part number and machine serial number before ordering
• Check spline specification, mounting dimension, and brake type
• Request strict pressure and performance testing before shipment
• Shockproof wooden packaging to avoid transit damage
• Quality warranty for manufacturing defects
