Kubota Excavator Slew Motor Problems & Solutions

Kubota excavators are known for their compact size, reliability, and efficiency on urban job sites and landscaping projects. However, even durable machines can develop hydraulic issues, with the slew motor (also known as the swing motor) being a frequent source of failure.

At Arena Hydraulic and Machinery, we specialise in slew motor repairs and high-quality replacements for a wide range of Kubota models — helping you restore swing performance efficiently and affordably.

Common Slew Motor Problems in Kubota Excavators

A malfunctioning slew motor can severely affect your machine’s functionality. Common signs include:

• Slow or sluggish swing motion
• Hydraulic oil leaks near the slew motor or gear reducer
• Loss of swing torque or power
• Unusual knocking or grinding noises
• Jerky or inconsistent swing performance

Typical causes include worn seals, damaged bearings, internal motor wear, and contaminated hydraulic fluid. If left unresolved, these issues can damage other critical systems and cause extended downtime.
