How do I test the hydraulic pressure in my excavator motor？

When your excavator or other hydraulic-driven machine starts acting strange—reduced power, slower movement, or abnormal noise—it’s often a pressure issue. Testing the hydraulic pressure in your motor is not just a maintenance step. It’s a smart move that can prevent serious failure and expensive downtime.

Hydraulic motors are designed to operate under very specific pressure ranges. Too high, and seals blow. Too low, and torque drops. A pressure test gives you clear insight into what’s going on inside. It’s a fast way to detect blockages, internal leakage, or pump inefficiency. You don’t need to tear down the system to get answers.

Testing is simple if you have the right tools. All you need is a digital or analog pressure gauge, suitable adapters, and access to your motor’s pressure ports. Always make sure the machine is shut down and depressurized before connecting tools. After installation, start the engine and run the motor under load. Monitor readings on both the supply and return lines. Compare them with the motor’s rated pressure. Any large difference means trouble.

A healthy motor runs within a narrow pressure band. If pressure spikes, it often means a blockage or misconfigured valve. If pressure drops, you may have internal leakage or pump wear. You might not need a new motor—just seals or valve tuning. A test helps you make the right call.
