Another power steering leak question.
As I mentioned earlier, I have drips of fluid under the coach and had
determined that the drip under the power steering pump was a leak from the reservoir hose to pump attachment. There are further drips to the left under the battery tray. I had assumed these were also power steering fluid (definitely not engine oil and it looked the same as the other drips) and were probably coming from the return hose to steering box connection. After much crawling, squinting and aiming with a flashlight I was able to see where the high pressure hose and return line attached to the steering box and there are no leaks at that point. There is a flat steel plate to the left of the back left battery and the leak is above that plate but so far I haven't been able to visually inspect it. Anyone have any idea what it might be? It is dripping onto the plate and migrating from there. It's not the high pressure hose (I think) because I can see most of it and it looks dry. PO said he thought it was jack leveling fluid but I've only used the jacks once and it drips everytime I drive it. Is there some other place on the left side of the steering box that might be leaking? Kerry 82 FC 35 Denver |

you may want to look at some other sources for power steering resevoir
every once in a while they come up on ebay look for a power steering resevoir for a mc5 bus comes with vent dipstick filter even the mount Stephen 77fc35 --- In WanderlodgeForum@yahoogroups.com, "davidkerryedwards" > > As I mentioned earlier, I have drips of fluid under the coach and had > determined that the drip under the power steering pump was a leak from > the reservoir hose to pump attachment.

Another power steering leak question.
The power steering reservoirs for the FC and PTs are not alike, the
FC model being a stand alone unit and the PT supplying the fluid for both the radiator fan and the power steering unit. The power steering reservoir on my former 1982 FC35 is a Purolator P-776-28 and uses a NAPA 1430 or fleetguard HF6195 filter. It does not need to be vented as some have suggested. If you properly install new hoses (just regular premium radiator hose) covered with 1 inch asphalt cloth wire loom which you can get from Bluebird it will work fine. The input and output of the reservoir has barbed connectors that will not leak if you take a little extra care in installing the hoses. After I cut both hoses to length I installed the asphalt loom over the hose and installed a 3 inch piece of heavy wall shrink tubing on each end to bind the loom to the hose so it wont fray. Before installing the hose to the barbed fitting I wiped a small amount of black silicone sealer to the inside of the hose and pushed it on and secure with a stainless steel hose clamp. I found that any leaks that I had were caused by the swivel fittings at the power steering unit itself. You can get the power steering unit rebuilt at Power steeringSpecialists at 1-800-235-3076 for $150.

But Tom, the venting trick works to stop the leak as it reduces the
pressure caused by hot fluid. Venting is a benifit and since it is a filtered system, non venting was an engineers oversight. I would however put the silicone on the metal fitting as not to be pushed into the hose and mixed with the ps fluid.

Another power steering leak question.
If I'm reading your post correctly, it sounds like you might have a
leak from the leveling valves beside the pilot's seat. It is a bit of a pain to R&R, but not bad to rebuild, just a bunch of o-rings and a dentist's pick. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "davidkerryedwards" > > As I mentioned earlier, I have drips of fluid under the coach and had > determined that the drip under the power steering pump was a leak from > the reservoir hose to pump attachment.

Another power steering leak question.
Yes, that's what the PO thought. But I think it is too far inboard
and forward to be the leveling jacks. The fluid is definitely red. Is the leveling fluid red? I got a different flashlight and peered in every opening I could again today. I'm now thinking again it might possibly be the return hose from the power steering box. When the light was just right, it looked like there was red discoloration around the insulation around the return hose indicating a possible leak. I rigged up a vent for the reservoir today, using 1/8 plumbing fittings on the dipstick hole so I'll give that a try and see what happens. It doesn't leak when its sitting, just after it's been running a while so I think the pressure from a non-vented system could be a major issue.

Another power steering leak question.
Kerry - The power steering hoses were all shot when we got our '84
FC. I changed them out as part of a project to replace all the hoses around the engine and transmission. You must drain the PS system to change any one hose, so best to just change them all. Also vented the system at the same time. Good insurance, and no fluid problems since.

Another power steering leak question.
Bob:
Did you tackle the job thru the floor by the driver? How long did it take? I'm thinking of switching to a synthetic power steering fluid to handle the heat better. Does anyone know at what temperature the power steering system should be running? I'm planning to use an infrared thermometer to see what mine is running at. I think I'm going to drive mine for a short while and see if venting the reservoir makes any difference. The original owner complained of power steering leaks right from the start.
