Daewoo Excavator Slew Motor Problems & Solutions

Daewoo excavators, particularly older models, are valued for their strength and simplicity. However, like all heavy-duty machines, slew motors (swing motors) can deteriorate over time due to wear and exposure to demanding environments.

If your machine is swinging slowly, making grinding noises, or leaking hydraulic oil, your slew motor may need repair or replacement.

At Arena Hydraulic and Machinery, we specialise in rebuilding and replacing slew motors for Daewoo excavators, ensuring your equipment remains dependable and productive.

Common Slew Motor Problems in Daewoo Excavators

With constant rotation and hydraulic pressure, these issues often develop:

• Seal wear and oil leakage – Results in pressure loss and reduced efficiency
• Torque loss or swing power drop – Caused by worn internal components
• Hydraulic fluid contamination – Leads to scoring and internal motor damage
• Worn pistons or bearings – Slows down swing speed or creates jerky movement
• Gearbox or reduction failure – Overloads and damages the slew motor
