How to Replace a Hydraulic Hose

Farm and heavy equipment uses a hydraulic pump,valve spools, and cylinders to perform their tasks. These components are interconnected with a series of steel tubes and steel reinforced rubber hoses, and the hydraulic oil may eventually begin to leak through these hoses, making it necessary to replace them. It can be a dirty job, but doing it yourself can save considerable expense and time.

Steps


  1. Locate the problem hose. This may be obvious if the hose has burst, since they typically handle oil at over 2000 PSI pressure, and one that bursts will discharge a large amount of oil in a short time. If the situation is a small leak, though, you will need to observe where the oil is dripping, and follow the wet trail it leads to the source. Never use your hands or body parts to find the leak. Use cardboard, paper or hydraulic leak detection fluid so no oil injection is accrued. A good hydraulic shop stocks leak detection additives that assist on location the leak safely.

  2. Assess how many components must be removed to facilitate replacing the damaged hose. Always label the component removed by number and letter so replacement of parts can be reinstalled with ease. This may include housings, guards, clamps, other hoses, hydraulic cylinders, and more. Follow the hose from one end to the other, noting the route you will use to uninstall and reinstall it. Putting a number and letter on the ports and hose ends.

  3. Determine if the hydraulic component the hose serves, or any other hydraulic components which must be removed have a live load, or weight on them. If the oil in the system you are disconnecting is under pressure, it may blow out forcefully when the fittings which hold it are loosened, causing oil to be discharged under pressure. Relieve the pressure from these cylinders or components before proceeding. ---- To be continued
