Cleaning the hydraulic hose connection points is an important step in ensuring a tight and leak-free connection between the hoses and the fittings. Dirt, debris, and rust can accumulate on the fittings over time and prevent a proper seal between the hoses and the fittings.
To clean the connection points, you should first remove the old hoses, if you are replacing them. Then, use a clean rag or a wire brush to remove any dirt, debris, or rust from the fittings. Clean the end of the hoses with a clean rag to remove any dirt, debris, or residue that may have accumulated on the hoses.
Inspect the fittings for any signs of damage, such as cracks or deformities. If the fittings are damaged, replace them before installing the new hoses. It’s important to ensure that the fittings are in good condition to prevent leaks in the hydraulic system.
Step 4: Apply Thread Sealing Tape
Wrap the threads of the fitting with thread-sealing tape. This will help to prevent any leaks and ensure a tight seal. Thread sealing tape, also known as PTFE tape or Teflon tape, is a thin, white tape used to seal the threads of fittings in plumbing and hydraulic systems. The tape is made of a flexible material that can conform to the threads, filling in any gaps or imperfections and preventing leaks.
Step 5: Attach the Fitting to the Hose
Screw the fitting onto the hose using a wrench. Make sure the fitting is tightly secured, but be careful not to over-tighten and damage the hose or the fitting.
Step 6: Check for Leaks
Once the fitting has been attached, check for hydraulic hose leaks by applying a small amount of hydraulic fluid to the connection point. If there are no leaks, proceed to the next step. If there are leaks, remove the fitting and check for any damaged threads or incorrect attachments.
Step 7: Repeat the Operation
Repeat Steps 3-6 for Additional Hoses and Fittings Repeat the steps for all the hoses and fittings in your hydraulic system.
Step 8: Fill the Hydraulic System with Fluid
Finally, fill the hydraulic system with a hydraulic fluid according to the manufacturer’s instructions. Make sure the fluid level is correct and check for any leaks.
