How do I troubleshoot a hydraulic motor issue?

When your excavator starts acting up, it’s not just annoying—it’s expensive. Slow response, weak digging force, or strange noises often point to one critical component: the hydraulic motor. This powerful part drives your machine’s movement. If it’s not working right, nothing else matters. Fixing it starts with smart troubleshooting.

First, check the basics. Low hydraulic fluid levels can cause loss of pressure. Dirty filters block oil flow. Air trapped in the system leads to strange noises and poor power. These are easy fixes but often overlooked. Always start here.

Next, test the hoses. Look for leaks, cracks, or swelling. A damaged hose reduces flow and builds up backpressure. That hurts your motor fast. Don’t ignore small drips—they usually turn into downtime.

Still not fixed? Now check the motor itself. Weak torque, excessive heat, or jerky movement can all point to internal damage. The shaft seals may be worn. The valve plate might be scratched. Bearings could be shot. You’ll need a technician—or better, a reliable parts supplier.
