Hitachi Excavator Slew Motor Problems & Solutions

Hitachi excavators are known for their efficient and durable hydraulic systems. However, even with robust build quality, components like the slew motor (also referred to as the swing motor) can wear over time due to high torque and pressure.

If you notice grinding sounds, hydraulic fluid leaks, or sluggish swing rotation, your Hitachi excavator’s slew motor may need servicing.

At Arena Hydraulic and Machinery, we specialise in repairing and replacing slew motors for a wide range of Hitachi models, offering solutions that are both cost-effective and long-lasting.

Common Slew Motor Problems in Hitachi Excavators

Due to constant torque and hydraulic stress, these issues are common in Hitachi swing motors:

• Contaminated hydraulic oil – Internal scoring and reduced motor performance
• Seal and O-ring failure – Results in hydraulic fluid leaks and reduced pressure
• Bearing and piston wear – Leads to weak or jerky swing movement
• Mechanical overload – Caused by heavy-duty cycles or sudden directional changes
• Overheating – Occurs during long-duty operations in warm climates

High-Demand Hitachi Models for Slew Motor Replacement

We support a wide range of Hitachi excavators, including:

These machines are heavily used in civil construction, demolition, earthmoving, and quarry operations, which places extra stress on slew systems.
