how to change hydraulic hose on l175 loader



Hydraulic hoses are vital components of machinery like loaders, and they play a crucial role in transferring hydraulic fluid to different parts of the equipment. Over time, these hoses can become worn out or damaged due to various factors, necessitating their replacement. In this article, we will guide you through the process of changing a hydraulic hose on an L175 loader. By following the steps carefully, you can ensure the smooth functioning and longevity of your loader.

1. Understanding the Importance of Hydraulic Hoses:

- The role of hydraulic hoses in loaders

- Signs of a worn-out or damaged hydraulic hose

Hydraulic hoses are responsible for transmitting hydraulic fluid or oil under high pressure from the pump to the cylinders, motors, or any other hydraulic components of the loader. These hoses are subjected to constant flexing, torsion, and high pressure, making them susceptible to damage over time. It is important to identify the symptoms of a failing hydraulic hose, such as leaks, cracks, or bulges, to avoid potential breakdowns or accidents during loader operation.

2. Gathering the Necessary Tools and Preparing for Replacement:

- Tools required for changing the hydraulic hose

- Safety precautions before starting the replacement process

Before starting the replacement process, it is crucial to gather all the necessary tools and equipment. Some of the common tools required include wrenches, pliers, a hydraulic hose crimping machine, a hose cutter, and safety goggles. Additionally, it is important to take safety precautions, such as wearing protective gloves and ensuring the loader is switched off before beginning any work.

3. Identifying and Locating the Faulty Hydraulic Hose:

- Inspecting the loader for the faulty hose

- Identifying the correct hydraulic hose to replace

Once the necessary precautions are taken, the next step is to locate the faulty hydraulic hose. Carefully inspect the hose connections, fittings, and other components to identify the damaged or worn-out hose. In case of confusion, consult the loader's manual or seek advice from a professional. It is imperative to identify the correct hose to avoid any mistakes during replacement.

4. Draining the Hydraulic System and Removing the Old Hose:

- Safely draining hydraulic fluid from the system

- Removing the old hose using appropriate techniques

Before removing the old hydraulic hose, it is essential to drain the hydraulic system properly to prevent spills and contamination. Utilizing a catch pan, carefully release the pressure by loosening the fittings, ensuring that all the fluid is collected. Once the system is drained, use appropriate techniques like loosening fittings or removing clamps to disconnect the old hose from the loader.

5. Installing the New Hydraulic Hose and Testing for Proper Functionality:

- Proper installation of the new hose

- Testing the hydraulic system and checking for any leaks

The installation of the new hydraulic hose should be carried out meticulously. Ensure that the new hose matches the specifications required for your L175 loader. Utilize the hose crimping machine to crimp the fittings onto the new hose, ensuring a secure connection. Once the new hose is installed, it is important to test the loader for proper functionality. Run the loader and inspect the connections for any leaks, making adjustments if necessary.


Changing hydraulic hoses on an L175 loader is a task that requires attention to detail and proper knowledge of the loader's hydraulic system. By understanding the importance of hydraulic hoses, gathering the necessary tools, correctly identifying the faulty hose, draining the hydraulic system, and installing the new hose with care, you can effectively replace a worn-out or damaged hose. Regular maintenance and prompt replacement of hydraulic hoses will lead to the efficient and safe operation of your loader.
