Hydraulic Motor Repairs

Diagnostics and troubleshooting for hydraulic motors

Our team of technicians follows a meticulous process when it comes to repairing a hydraulic motor, no matter what the variety or brand is.

Our entire team’s goal is to provide you with the very best, most accurate motor repair as quickly as we can while minimizing your downtime.

The process begins with diagnostics. Our technicians will fully analyze your motor and identify the origin of the breakdown. Every motor we receive is disassembled and thoroughly cleaned and inspected. It is then checked for a precise fit and tolerances. Any parts that are worn down, broken or missing are compiled into a list for replacement.

We will let you know what needs to be done to repair the motor and inform you of any recommendations our technicians have that would improve the motor’s performance.

How Do Hydraulic Motors Work?

Hydraulic motors operate using pressurized hydraulic fluid. This fluid is critical for the operation of a hydraulic motor, as it transfers power between the pistons and turns the motor, delivering an increased output of force and requiring less start-up power.

A basic hydraulic motor contains two pistons separated by tubes that hold hydraulic fluid. When one of these pistons moves it displaces the hydraulic fluid, which cannot be compressed. The pressure from the first piston, plus the pressure from the fluid, is transferred via the tubes to the second piston. This is what turns the motor.

All hydraulic motors have three common features:

  • A surface area that is subject to the pressure differential
  • A method of controlling the porting of the pressurized fluid to the surface
  • A connection between the surface area and an output shaft

The performance of the hydraulic motor depends on:

  • The ability of the surface to withstand force
  • Leakage characteristics
  • Efficiency of the method used to link the pressure surface to the output shaft

And the performance of a hydraulic motor is measured by:

  • Pressure Flow
  • Torque Output
  • Speed
  • Volumetric and Mechanical Efficiencies
  • Service Life
  • Physical Configuration

Common hydraulic problems

Telltale signs of hydraulic problems include:

Seal leakage

Seals are used to keep the hydraulic fluid pressure contained. They’re a key part of a hydraulic motor. Over time, the seal material can weaken, and they can begin to leak. In some cases, extreme pressure under load can cause a seal to blow out.

Pressure fittings

A hydraulic motor has two pressure fittings – one for each hydraulic line that has fluid entering and then leaving the motor. But while built from strong stainless steel alloy, these fittings can degrade at their attachment points.


When disassembled the most easily spotted part of a hydraulic motor, pistons operate within the cylinders with precise levels of tolerance. Any wear will bring a loss of hydraulic pressure.
