How to Remove a Hydraulic Hose from a Bobcat Oil Cooler


When the time comes to replace or repair a hydraulic hose on your Bobcat, it is essential to know the correct procedure for removing it from the oil cooler. The oil cooler plays a vital role in regulating temperature and maintaining hydraulic fluid quality within your Bobcat machine. This article will guide you through the step-by-step process of safely removing a hydraulic hose from the Bobcat oil cooler, ensuring that you can perform this task efficiently and effectively.

1. Understanding Hydraulic Systems:

Before diving into the removal process, let's first gain a basic understanding of how hydraulic systems in Bobcat machinery work. Hydraulics utilize high-pressure fluid to generate mechanical force, allowing the machine's various functions to be performed. Hydraulic hoses play a critical role in transferring this fluid from one component to another, ensuring smooth operation of the machine.

2. Safety Precautions:

Always prioritize safety when working on machinery. Before starting any maintenance or repair tasks, ensure that you have proper personal protective equipment (PPE) such as safety goggles, gloves, and a full-body coverall. Additionally, make sure the Bobcat machine is turned off and parked on level ground to reduce any risk of accidental movement.

3. Identifying the Hydraulic Hose:

Locate the hydraulic hose that needs to be removed from the Bobcat oil cooler. Depending on the model and configuration of your Bobcat, the location of the oil cooler and hydraulic hoses may vary. Refer to the manufacturer's manual or consult with a professional if you are unsure about the hose's exact location.

4. Relieving Pressure:

Before disconnecting a hydraulic hose, it is essential to relieve any pressure within the system to prevent any potential accidents. Start by activating the Bobcat's auxiliary control to release hydraulic pressure, and then turn off the machine. After this, you will need to disable the ignition to ensure that no unexpected hydraulic pressure builds up.

5. Draining Hydraulic Fluid:

Place a drain pan underneath the Bobcat's oil cooler to catch any hydraulic fluid that may leak during the removal process. Ensure the pan is of suitable size and capacity to avoid spills. Open the drain valve to allow the fluid to drain out completely. Once all fluid has been drained, close the valve securely.

6. Detaching the Hose:

Using a wrench or an appropriate tool, carefully loosen and remove the fittings that secure the hydraulic hose to the oil cooler. Ensure that you have a firm grip on the hose while doing this, as it may be under residual pressure or tension. Once the fittings are loosened, gently pull the hose away from the oil cooler. If the hose is stuck or difficult to remove, applying a small amount of penetrating lubricant can help ease the process.

7. Inspecting the Hose:

Take a moment to inspect the removed hydraulic hose for any signs of damage or wear. Look for cracks, bulges, or any other abnormalities that may indicate the need for immediate replacement. It is crucial to address any issues promptly to avoid equipment failure or potential hazards in the future.


Removing a hydraulic hose from a Bobcat oil cooler is a task that requires careful attention to ensure both safety and efficiency. By following the step-by-step process outlined in this article, you can confidently remove the hydraulic hose without causing damage to any components or putting yourself at risk. Remember, if you encounter any difficulties or are unsure about any step, it is always recommended to consult with an expert technician or refer to the manufacturer's manual for guidance.
