how to change hydraulic hose on bobcat


Hydraulic hoses are integral parts of industrial machinery, and the Bobcat equipment is no exception. These hoses often require regular maintenance and occasional replacements to ensure optimal performance. Learning how to change a hydraulic hose on a Bobcat machine can save you time and money, as well as prevent potential breakdowns. In this article, we will guide you through the step-by-step process of replacing a hydraulic hose on a Bobcat, along with some essential tips and precautions. Let's get started!

Understanding Bobcat Hydraulic Systems

Before delving into the process of changing a hydraulic hose, it is crucial to have a basic understanding of the hydraulic system in a Bobcat machine. Hydraulic systems in Bobcat equipment use pressurized fluid to generate power and control various functions. These systems consist of hydraulic hoses, fittings, pumps, cylinders, and valves, all working together to provide the necessary force for efficient machine operation.

1. Assessing the Hose Damage

The first step in replacing a hydraulic hose on a Bobcat is to assess the hose for any signs of damage or wear. Inspect the hose thoroughly, looking for leaks, cracks, abrasions, or bulges. Running your hands along the hose can help identify any abnormalities. Additionally, check the hydraulic fluid level and color for signs of contamination or degradation.

2. Gathering the Required Tools and Materials

Now that you have identified the damaged hydraulic hose, gather the necessary tools and materials to complete the replacement. Some common tools include an adjustable wrench, pliers, a utility knife, safety gloves, and safety glasses. You will also need replacement hydraulic hose(s), fittings, and the appropriate hydraulic fluid specified by the manufacturer.

3. Preparing for the Replacement

Before proceeding with the replacement process, ensure that the Bobcat machine is turned off and parked on a level surface. Release the pressure in the hydraulic system by moving the controls back and forth several times. Next, consult the user manual or the Manufacturer's Service and Repair guide for specific instructions on your particular Bobcat model.

4. Removing the Damaged Hose

Using an adjustable wrench, carefully loosen the fittings connecting the damaged hose to the hydraulic system components. Be cautious while unscrewing the fittings to avoid damaging them or the hydraulic lines. Once the fittings are loose, remove them and detach the damaged hose from the system. It's essential to have an appropriately sized drain pan handy when disconnecting the hose to catch any residual hydraulic fluid.

5. Installing the New Hose

With the damaged hose removed, it's time to install the replacement hose. Coat the threads of the fittings with hydraulic fluid and connect them to the respective hydraulic system components. Ensure a secure fit but do not over-tighten the connections, as this can cause damage. Use pliers or an adjustable wrench to achieve a snug fit without excessive force.


Changing a hydraulic hose on a Bobcat machine may seem daunting at first, but with the right tools, materials, and knowledge, it can be a straightforward process. Regularly inspecting hydraulic hoses for damage and promptly replacing them when necessary is crucial for maintaining the productivity and longevity of your Bobcat equipment. By following the steps outlined in this guide, you can confidently tackle hydraulic hose replacement, ensuring optimal performance of your Bobcat machine. Remember, safety should always be a priority, so wear appropriate protective gear and consult professional assistance whenever needed.
