Replacing Hydraulic Hose Fittings
Hydraulic hose fittings are always designed to tolerate heavy use and abuse. They can last for quite some time but once they break down and get damaged, you will have to organise for replacement instantly. Hydraulic hose service is not a difficult process to handle. You can easily do the job even with little plumbing or mechanical experience. Follow these easy steps to help you replace your hydraulic hose fittings.
What You Will Need
Having the right tools and materials is the first step to achieving a successful project. Ensure you have the new hydraulic hose fittings to be replaced, clamps, chains, a pipe wrench, a multipurpose wrench, rags, buckets, working clothes, work gloves, and protective eyeglasses.
Examine the Main Problem
Start by carrying out a visual inspection of the whole hydraulic pump to determine the level of damage on the hose fitting. Lay the hose down on the ground and check carefully to locate the leaking hoses and damaged fittings. Once the problem is located, mark the areas and get your tools ready to replace the fittings and other damaged components.
Release Pressure on Hydraulic Cylinders
Ensure you relieve pressure on the hydraulic cylinders of the hose fitting before you make any repair attempt to prevent a blowout which might cause injuries.
Disassemble the Hose Components
Some of the components of the hydraulic hose -- such as clamps, guards, the housing, and many other parts -- must be removed to repair the broken or damaged hose fitting. Be careful to note all the locations of the components to avoid confusion. You may consider taking pictures before you disassemble the hydraulic hose.
Remove Hose Fitting
Most hose fittings will swivel when the hydraulic hose pump is switched on. Use two wrenches to remove the swivel parts. The fittings may have two couplings, therefore, you will have to clamp one wrench on one side of the coupling to firmly hold it and a second wrench to allow turning of the other coupling. Apply a lubricant if the couplings are stuck in place to help loosen them up.
Clean Thoroughly and Replace the New Fittings
Clean the fittings thoroughly after removing the hose using a rag. Make sure no dirt or debris enters the machine to contaminate it. Put the fittings back after cleaning using the pictures you took as a guide. Install all the components with the new fittings while ensuring guards and clamps are in their proper places. Return cylinder pins properly before replacing the snap rings that hold the pins in place.
