Kobelco Excavator Slew Motor Problems & Solutions

Kobelco excavators are known for their durability, smooth operation, and fuel efficiency. However, like all hydraulic components, the slew motor (also called the swing motor) can wear over time due to constant torque and operational stress.

If your machine is swinging slowly, leaking oil, or producing strange noises, your slew motor may require attention.

At Arena Hydraulic and Machinery, we provide specialised repair and replacement solutions for Kobelco slew motors. Whether you need a rebuilt unit or a full replacement, we offer cost-effective options built for reliability.

Common Slew Motor Problems in Kobelco Excavators

Continuous operation under pressure leads to the following issues in Kobelco swing motors:

• Contaminated hydraulic fluid – Damages internal components and reduces efficiency
• Seal and O-ring failure – Leads to oil leaks and swing pressure loss
• Piston and bearing wear – Causes sluggish or weak swing movements
• Shock load stress – Heavy attachments or rough terrain can overstress the motor
• Overheating – Long cycles and poor cooling reduce motor lifespan
