Replacing A Hydraulic Hose

When you notice that a hydraulic line has a leak, it is time to replace it in order to minimize the loss of hydraulic fluids and to ensure that the device continues to function properly. Even if the hose does appear to be functioning properly, it should be replaced if it is at least ten years old. The cost of replacing a line is much lower than the cost of the loss of fluids, the damage done to surrounding equipment and any injuries to others.

Locating The Leak

Before you replace the hydraulic line, you will want to find out exactly where the leak is located. Fortunately, if your hydraulic device is used over a dry surface, you will be able to locate any areas where the hydraulic fluids have dripped and formed oily spots. Use cardboard or paper to determine where the leak exists, rather than relying on your hands. Also, take a look at the associated fittings and other parts to determine if they need to be replaced.

Checking The Hose

Before removing the hose, it is important to make sure that the hose is not live. If you do not shut down the hose before you remove it, you could place yourself under a hazardous situation.

Removing The Components

Determine which components must be removed in order to replace the hose. Label the components with letters or numbers so that it is easier to remember where each component belongs. Place the numbers on the port and hose ends. Then, proceed to remove these fittings and the old hose. 

Protecting The Hose

To avoid contaminating the new hose, you will want to place special caps over the ends of the hoses to make sure that contaminants do not enter while you are routing the hose through the hydraulic machinery. These can be removed before installing the fittings.

Tightening The Connectors

Tighten the connectors to secure the ends of the new hose. Replace all of the necessary components using the letters and numbers marked on the components. Make sure that everything is properly put in place. Then, check the fluid levels of the machine and check for leaks. The hydraulic circuits will require some bleeding, which involves the removal of air, before the machine can be put to use. However, once the hose has been completely replaced, you will then be able to use the machine again.

If you don't feel comfortable replacing the hydraulic line by yourself, have a company like Cam Co do the repair for you.
