HWH hydraulic lines - ebirder2000@... - 10-26-2007 10:12 Most NAPA shops should be able to cut off the old connector and put on a new end on the hose for you. The hard part will be removing and reinstalling the hose from the coach. Steve Anderson 79FC35 Poulsbo, Wa. (Heading south for the winter now in Lodi, Calif.)

Bruce 1988FC35 HWH hydraulic lines - Curt Sprenger - 10-26-2007 14:26 Bruce, A lot of things can be done to repair hydraulic lines...cut, add, etc. Why do you say the line weight is too much weight for the end fitting? Seems strange that the line and fittings support the jack. I'd take a good look at the fittings themselves. I had one rear jack on our 87 PT38 that had an oil leak at the top/line fittings, and by tightening up the two coupler fittings (that I suspect loosened up over many year) resolved the leak. Discuss your situation with a good hydraulic repair shop if needed. n 10/26/07, birdshill123 > > It has been a while since I have done any hydraulic repairs.

That line is not supported by any clips. Thus the weight of the line is applying pressure to the end fitting. That I can easily fix. I do not wish to emove the old line as it is one piece to under the door area of the MH. Would mean cutting a million wire ties. I think I found what I need. They are no crimp ends. I can cut the line near the jack and have a new short line made at a hydraulic shop. Then I will use a no crimp fitting to join the new to the old. Bruce 1988 FC35 HWH hydraulic lines - Gregory OConnor - 10-27-2007 03:27 Many Hydraulic lines have one end fixed and one end with a spin fitting (like the female end of a garden hose). You may want to mark the orientation of the old line and maintain it with the repair as the inner ply may come apart if the 20 year old line gets twisted out of memory shape. The line holds ram psi when the jacks are down and the bus is perched atop. The hose is working while the pus is perched when mounting a close attachment point, your design should realize the up and down position of the ram fitting if it changes at all. It may be that some length of free hose is requires to accommodate a change from up and down. I wonder how much of the failure is caused by lack of support and how much is caused by degraded hose. I believe degraded hose is a cause that your repair will not completely address. You may find that the airquip type of no crimp may fail next if the hose is brittle. I gave up using onsite repair of lines because the second failure is complete and messy (however predictable).

I find that they get very brittle when they are 20+ years old and break easily.
