Power Gear Hose Failure

Has anyone ever seen anything like this pic? A close friend has a 2007 Coachmen Cross Country class A with Powergear jacks. He called me this weekend and said he noticed bulging and bubbles on his hydraulic jack lines. I wasn't sure what he was talking about so I went and looked. The hoses in the compartment where the pump is located are bumpy and one has a huge bubble.

He called a local repair shop and was quoted almost $1500 to replace all the hoses, even though the only problem appears in that front compartment. The dealer said those hoses are "proprietary" and come in sets, so you have to replace them all.

Has anyone ever had this happen? Could a hydraulic shop make "patches" or would it be possible to cut out the bad and splice in new?

I have the same exact system on my 2007 coach and mine look nothing like this. His jacks work fine, but he's afraid of a catastrophic failure that leaves the jacks extended.

I suggest removing the hoses and taking them to a hyd hose repair shop and they can make you new hoses.

The problem with that is the hoses are one piece and run from the front to the rear and back (to each jack). If you have to go that far, might as well replace them all. Also, it appears they were installed prior to the body being built, so to remove them will just require cutting them all loose and leaving some in the chassis, then running the new ones elsewhere.

Had the same thing happen to my power gear system on a 2006 Revolution. I noticed bubbles in all my hoses at the manifold. The dealer chalked it up to age. I had them all replaced. My extended warranty provider covered the repairs. I would recommend having them all replaced even if some are not bubbling..

the hoses are NOT proprietary! no system that i know of comes in a matched set.
with jack hoses, any hydraulic hose that matches your hose in fittings and pressure parameters will work. it doesnt even have to be the same length. a few inches one way or the other doesnt matter. hwh does require equal length hoses on its slides, but even those can be made up by a local supplier, if you dont order them from hwh
again, fittings and more important pressure ratings are all thats required.
hwh uses parker hose, 1/4 hose is 4000 lbs, and 1/8 hose is rated at 6000 lbs.

the bubbles indicate an internal leak inside the hose covering. theres no way of knowing where it is, so its best to replace the complete hose. if its happening on more than one hose, i would replace them all. its just good practice.
again, they are not proprietary.

So, would it be possible to cut out and replace the bad section, splicing in a new piece?

it depends on how bad the hose is. also, it would require the removal of the hose anyway. not many people are willing to splice a hose to start with, much less, do it on the coach,
so, its possible, depending on how bad the hose is, and whether someone will do it.
but not probable. i personally would not do it.
the chances of a failure would outweigh any savings. i would never guarantee a repair on a hose that looks like the one you posted.

When hoses are made they are tested for leaks. Trying to do that on the MH would be a nightmare and expensive.

Yes, two years ago my 2008 had bubbles on two of the hoses. I told them to replace them all. Hoses alone were around $800 for all of them.

It is what it is, and then it is what you make of it.

The hoses can be made up by any reputable hydraulic shop, tie a stout string to the original hose ,remove clamps / zip ties, note where any anti chafe and/or heat shields (phone pics?) are located and pull the bad hose out allowing the string to follow the route out. Then you can pull the new back using the string.
Be sure the shop notes the correct fittings and hose rating. They are JIC/SAE type
the hose should have some SAE rating numbers on it if they are still visible.
Of course you must be somewhat mechanically inclined and don't mind getting dirty.
Be sure to cap or somehow cover the ports after hose removal and be sure to remove the fuse that powers the system prior to starting for safety sakes.

Addendum to above, of course you will have to bleed the new hose of air,
be safe use googles, gloves, and extreme caution as the pressures can get high.
Have a professional bleed the system if you are not confident in your abilities with
doing it yourself.

This was all recently resolved. My friend took the MH to a local dealer, who replaced all the hoses to the tune of $2,000.

$2000 sounds reasonable to me. After on of the posters descriptions of the "easy" do it yourself replacement.
