For heavy and agricultural equipment to manage their tasks require cylinders, spools and hydraulic pump. These are components that are usually assembled together using steel pipes and steel reinforced rubber hoses. Oil leakage is a very common problem for hoses, and when this happens, it may require replacing the hose. The good thing about hydraulic hoses is that you can easily replace them, saving money that you would otherwise use when hiring a specialist to help you with the replacement. A few steps will help you easily manage the replacement process.
Step 1 - Identify the problem hose. A leak usually indicates an explosion, considering that the hoses withstand high pressures. A wet footprint can lead you to the source of your problem. You can use paper or cardboard leak detection paper to help you find a leak faster instead of using your hands.
Step 2 - Evaluate components for removal. To replace a damaged hose, you will need to remove some components, and to avoid confusion when reassembling, it is best to mark the parts as they are removed. Among them will be, among other things, clamps, fences, cylinders and shells.
Step 3 - Determine the load on the hydraulic components. The components serviced by the hose may be blown out if they are under pressure when disconnected. Before proceeding, relieve pressure from components or cylinders. Any fasteners supported by a cylinder operating from a hose must also be chained or lowered to the ground so that it does not fall under pressure.
Step 4 - Remove attachments and clips. You will need the right tools, such as a wrench. In addition to the hydraulic cylinder, you must also loosen the fittings that attach the hoses to the system, and they should be turned on the threaded connection without twisting other parts.
Step 5 - Remove the hose and clean it. Beware of leakage when removing the hose and consider connecting the nozzles on the machine to remove debris from the system; You can fasten a clean rag around the fitting for protection. Then you can wipe off the excess oil on the hose before taking it to the consumables store for a new order. You should also make sure that you clean the fittings before reinstalling the new hose.
Step 6 - Connect new hose ends. A special cap or clean cloth can be used to prevent debris and dirt from entering the hose when it is returned. Temporary plugs can be removed immediately after fittings are installed.
Step 7 - Thread fittings back and replace other components. Torque may be useful if the fittings are tightly connected, but make sure that you do not finish trimming the threads or damage the seals. By marking the removed components, it will be easy for you to replace them in your correct places. Make sure that snap rings or split rings are reinstalled.
Step 8 - Check the oil level in the car and the fluid. Acid may be required for some hydraulic circuits before using the machine. Raise the system and check for leaks. Clean up previous surface leaks so you can easily see new leaks.
