John Deere Excavator Slew Motor Problems & Solutions

John Deere excavators are known for their durability and dependable performance across construction and earthmoving projects. However, with ongoing usage, key components like the slew motor (swing motor) are prone to wear and may need servicing or replacement.

If you notice your John Deere machine swinging slower than usual, experiencing jerky movement, or leaking hydraulic oil, it may be time to service the slew motor.

At Arena Hydraulic and Machinery, we provide expert slew motor repairs and OEM-grade replacements for a wide range of John Deere excavators.

Common Slew Motor Problems in John Deere Excavators

The slew motor plays a vital role in the upper structure’s rotation. Common problems include:

• Hydraulic fluid contamination – Leads to internal scoring and component wear
• Seal and O-ring degradation – Causes leaks and loss of swing pressure
• Worn pistons and bearings – Results in unsteady or weak swing response
• Overload or impact damage – Often occurs in rough terrain or under heavy loads
• Thermal stress or poor cooling – Accelerates wear in long-duty cycles
