JCB Excavator Slew Motor Problems & Solutions

JCB excavators are well-regarded for their strength, versatility, and performance on construction and earthmoving jobs. But over time, components like the slew motor (swing motor) can wear out and cause serious performance problems.

If your JCB excavator is struggling to rotate, leaking hydraulic oil, or producing grinding sounds, it may be time to service or replace the slew motor.

At Arena Hydraulic and Machinery, we specialise in professional JCB slew motor repairs and replacements, restoring your machine’s swing power with quick and cost-effective solutions.

Common Slew Motor Problems in JCB Excavators

Constant load and usage lead to typical symptoms such as:

• Slow or jerky swing movements
• Oil leaks from slew motors or gearboxes
• Grinding or knocking sounds during rotation
• Complete loss of swing function
• Hydraulic pressure loss or system overheating

These issues are caused by:

• Seal wear and internal component damage
• Bearing failure
• Hydraulic oil contamination or low-quality fluid
