Swing Reduction Gearbox 582-8286 595-9502 607-5642 595-9505 for E374 E395GC Excavator

This swing reduction gearbox, available under part numbers 582-8286, 595-9502, 607-5642, and 595-9505, is the swing transmission unit specially designed for the swing system of E374 and E395GC excavators. It reduces the output speed of the swing motor and increases torque to drive the upper structure to rotate.

The unit adopts a planetary gear structure with wear-resistant alloy gears and precision machining. It is designed for direct replacement installation and delivers stable torque output performance for heavy-duty mining and construction working conditions.

• Internal gear and bearing wear, resulting in insufficient swing torque and weak rotation.
• Internal oil seal damage, leading to hydraulic oil leakage.
• Abnormal impact noise and vibration during swing operation.
• Planet gear stuck, causing swing failure.
• Gearbox housing cracks caused by overload and impact.

• Confirm the part number and machine serial number before ordering.
• Check gear ratio, mounting dimensions, and spline specification.
• Request strict torque and load testing before shipment.
• Shockproof wooden packaging to avoid transit damage.
• Quality warranty covering manufacturing defects.
