Slide hydraulic hose issues

Yahoo Message Number: 79324
I know this topic is not a new one, but thought I would share what I've learned so far. I have an 06 Intrigue #12068 and have many leaking hose fittings and bubbling on 3 hoses. After reading all of the older posts and researching the issue, I've discovered there is a lot of confusion about what is causing the leaks and bubbling. I called OMC and spoke with Vern, who spent the time on the phone with me to explain the history of the issue and shared their current thinking on the cause. OMC has done testing and determined the leaks are due to the crimps not being up to spec. If the swage die used in the crimping tool is worn beyond a very tight tolerance, the resulting crimp won't be 'tight' enough. This condition will eventually allow hydraulic fluid to leak out around the fitting and also seep between the 'inner' hose and the outer sheath, causing the bubbling to occur. Once this happens, the bubbling will worsen quicker for hoses located in areas where they are exposed to high amounts of heat. I have the Cat C-13, which has the turbo-charger mounted on the opposite side of the engine and there is not an 'excessive' amount of heat being transferred into the PS tag axle wheel well. Yes, there is plenty of heat anywhere in the vicinity of the engine, but not sufficient on its own to cause hose failures of properly built hoses.
I have US Warranty coverage and they too are up to speed on this issue. They are working with me to address the leaks, and have no problem paying to replace all of the leaking fittings. I am considering replacing all of the hoses on my own, as opposed to just replacing the fittings, and considering performing the work myself. Has anyone self-performed this work? I would love any tips on removing the decorative woodwork on the inside of the PS bedroom slide. I'd also like to hear of any tricks to bleeding the air from the system once the new hoses are installed.

Thanks in advance - Gary 06 Intrigue #12068

Gary, It is my understanding that HWH's Crimping Die and Tools are proprietary to HWH. This information came to me from a retired HWH Tech, but I don't pretend to be 100% on this info.

Thanks, Mike 03 allure 1st Ave. #30898

Doug Beaudry was my go-do guy (then as Country Boys, now with Country Coach Corporation) on the HWH hoses. He knows about all there is to get at them and fix them right.

Also, Doug's a great guy IMHO.

Be aware, one leaking fitting spraying oil in engine compartment = extreme fire hazard. Can you say, by by coach. Making good fittings is learned, would not recommend for the typical DIY unless you have a good tutor to show the finer points.

To replace your hose's on bed room slide you will have to pull the wheel off the tag or be real small as the sequencing valve and hose junction is in there in side the coach there are two narrow pieces of trim that cover the screws holding the moldings on each end of the slide just carefully remove them as they are installed with small finishing nails then under the drawers you will remove the piece that is carpeted the screws are easy to find and there are your hoses the hoses for that slide seem to be the most troublesome as the factory ones will not take the heat ! so i suggest that you move the valve forward away from the heat and and then have the hoses made to length and run them thru a heat resistant boot and your hose problems will be solved

Gary & Denny. I am under the impression that CC issued a revision on the location of the sequencing cylinder for the intrigue with the Cat engine. The heat has caused at least one fire. I know of one 07 intrigue with a Cat engine that had the cylinder relocated Bob 06 intrigue 400 ISL 12047

Thanks for the tip Leonard. My intention is to replace the hoses with new ones procured from HWH, as I agree, making hydraulic hoses should be left to professionals with the right equipment. Installing them is not that difficult, the routing is the hard part!

Replace one at a time will be the thing to do. As for bleeding, some of the slider room installs have complicated and very step by step instructions for bleeding. Might find the manuel online, have personnel found the manuals I have needed for HWC. If all else fails, ask them for the instructions when you purchase the hoses. Would not try without the instructions are may cause structure damage. Good luck.

Thanks Denny! Your trim removal instructions were right on! Now for the fun part...

something to think about !! I found that the hoses that CC used was about 2 feet longer than they should have been so they just wrapped them up in a wad and tie wrapped them that was not good !! also those hoses were not designed to take heat if you are not moving the valve be sure and measure for proper length I highly recommend that you talk to Bob Vinson or Tom at OMC as to were to move the valve to !! If you are going to pull the tag wheel why don't you have the drivers pulled at the same time and be done with this problem
Good luck

Denny - While speaking with Vern at OMC, I found out that they are no longer so sure about heat being a big factor in these hoses failing. I inquired about it because I didn't see any reason why there would be excessive heat in that area. Vern told me they had thought at one time that it must have been heat, but their testing indicated it was actually the quality of the crimp on the hoses that was the culprit. The heat present in the wheel well will tend to accelerate the bubbling once the failed crimp has allowed seepage between the layers. If I understood him correctly, there is no need to relocate the sync cylinder, just replace hoses with new ones which are properly crimped to spec. Maybe someone else can weigh-in on this and to see if I understood Vern correctly.

Gary: Since I was "only" 200 miles from HWH in Moscow, Iowa I went to them and had them replace the hoses above the tag tire on the passenger side. They seemed to think heat might be a problem because they wrapped them with some kind of sleeve that was supposed to help insulate them. You might call HWH and visit and see what they say. They are really nice and helpful.
