Swing Motor Assembly 295-9414 20R6246 for E374D E374F Excavator

This swing motor assembly, identified by part numbers 295-9414 and 20R6246, is a hydraulic drive unit purpose-built for the swing system of E374D and E374F excavators. It converts hydraulic pressure into torque to rotate the machine's upper structure.

The unit features a high-torque piston design, precision sealing, wear-resistant alloy construction, and precision machining. It is engineered for direct replacement installation and delivers stable output performance under heavy-duty mining and construction 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 sticking, leading to swing brake failure
• Housing cracks caused by overload and impact loads

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