Power gear hydraulic lines bulging...

I have a 2005 38ft Class A Gulf Stream with 4 jacks and 2 slides that are hydraulic driven. My problem is that most of the hoses have some degree of what looks like bulges on them.

I would like to know if this is an indicator of failed hoses or is this a common thing with hydraulic hoses?

Any suggestions or ideas on what needs to be done and or how much this may run to repair would be appreciated. Thanks

Sounds like the fluid has made its way to the outer casing on the hoses. Some good auto parts stores can make hoses to your length needed. If you can do the labor it shouldn't be to expensive.

Not good when those hoses bulge, they operate under a lot of pressure. To answer your question, Yes that is an indication of failure. If they burst you will have a nasty mess which will be the least of your problems.

I am not sure that I would go to an automotive repair store to have them made. Times I have priced them they were expensive. Try going to a tractor dealer. See if the hose ends are metric or standard if they are metric go to a Kubota or someone like that. IF they are standard try john deere or one of the American brands. That has always been cheaper for me.

And to echo another poster. YES that is a sign of hose failure.

Go to a towing service,, Ask them where they go for hoses. Go there.

This is an estimate based on the diamater of my jacks and the weight raiting of same but I think "Thousands of pounds of pressure" is reasonable for those lines.

I do have a question for the hydraulic engineers here.

How practical would it be, at least on the rear jacks, to go with a STEEL line for most of the run?

Hose from pump assembly to long steel tube,, Hose from there to jack But Steel for the majority of the run.... (Like the hydraulic brakes on your car)

Home is where I park it!
