How would I replace these hydraulic hoses? They look like they are crimped around the pipe and I'm not sure I can remove them.

Usually you'd buy hydraulic hose with fittings already on it, but the other side of the hose is only held in place with a pipe clip so maybe this isn't such a high requirement application.

How would I disconnect the 2 hoses on the left side? What kind of connector do those use?

On oddball shit like that you can slit down the crimped portion with a cutoff wheel on a grinder until you get through to the rubber. Do it two or 3 times around the crimped ferrule. then pry it off and pull the hose out. That way you can re-use the original fitting.

Some fittings have the ferrule made onto the fitting itself. IF that is the case you will have to cut around the end of the crimp carefully to remove it as well.

Once you have the old hose removed you can either braze a NPT or JIC fitting to it to adapt it to a more commonly used hydraulic hose, or adapt it some other way.

Pull the bolts on the left side and the fittings will come off. They are called banjo fittings. Yours look really oddball as they usually aren't that thick. Might have copper crush washers, or o-rings to make a seal.

Huh. We have banjos in telecomm, too. They're basically boards with flat slabs of copper (one per wire) rhat you grip with alligator clips. Used for diagnostics.
Funny how engineers grab for the same kinds of words for things.

In the hydraulic or air fittings world a banjo bolt is any bolt that has been gun drilled up through the shank and then side drilled so it has a fluid passage through it. They are very common in brake systems on the calipers. They are also used in some hydraulic systems on equipment and I have even seen some in compressed gas/air systems a time or two.

The left is usually just the hose slid onto the fitting (like on the right) and then a metal sleeve crimped on top. You can use a Drexel to slice the sleeve and remove it, then just put a new hose on and then have e clips at both ends

Id just take it to a hydraulic shop and have them crimp on new hoses.

Unless it is some big time hydraulic shop that does nothing but hydraulics and hoses all the time, OP is going to have to do a little prep work. The local Napa that crimps hoses is not going to be able to do anything that will work for this, as it is a non standard fittng.
