How to Replace a Hydraulic Hose Fitting

If you choose to go it alone though, you’ll need a few tools. They are; new hydraulic hose fittings; chains; clamps; a pipe wrench; a multi-purpose wrench; rags; buckets; suitable clothing; working gloves and protective eyewear.

Right, let’s get started:

Step One: Find the problem areas and relieve the pressure on the hydraulic cylinders

Perform a visual inspection of the hydraulic pump to figure the extent of the damage suffered. To find the damaged fittings and leaking hoses, lay them on the ground in a well-lit area and check carefully. Anything that looks suspect should be marked.
Then you need to relieve the pressure on the hydraulic cylinders in order to prevent a blow-out or serious injury as you move on to step two.

Step Two: Remove the hose components

In order to remove the fittings, you’re going to have to remove some of the components in the hydraulic hose, including the guards, the clamps and housing. It’s always best to take pictures of each step of removal, so you can recall which part goes where when you reassemble later. With the photos taken, label each part and place them to once side.

Step Three: Remove the offending hose fittings

The majority of hose fittings swivel when
the hydraulic pump is turned on, so you’ll need two wrenches in order to remove the swivelling parts – one to hold, and one to turn. Most fittings have two couplings, so that’s where you should place your wrenches.

If you find they’re stuck, try using some lubricant to loosen the couplings. If you’re removing the hose too, you’ll need to loosen the fittings attached to the hose and pull them out.
