Volvo Excavator Slew Motor Problems & Solutions

Volvo excavators are renowned for their power, fuel efficiency, and versatility in applications ranging from civil construction and demolition to mining and landscaping. But even these high-performance machines experience wear, especially in key components like the swing motor (slew motor).

If your Volvo excavator is swinging slowly, leaking oil, or producing abnormal noises, it may be time for a repair or replacement.

At Arena Hydraulic and Machinery, we specialise in slew motor services for Volvo excavators, offering both expert repairs and high-quality aftermarket units tailored to your model.

Common Slew Motor Problems in Volvo Excavators

Slew motors are responsible for the swing movement. When they fail, machine performance drops significantly. Here are common symptoms:

• Slow or unresponsive swing
• Knocking or grinding noises during rotation
• Oil leaks from the swing motor housing
• Low swing torque or loss of rotational power
• Erratic or jerky swing motion

These problems are usually caused by:

• Contaminated hydraulic fluid
• Worn or failed seals
• Internal wear on bearings, pistons or gears
• Excessive operational stress or overload
