69 p/s hose help

[Greg L.]

Well I attempted to install my p/s hoses that I bought about 4yrs ago(man this restoration is taking a long time) and low and behold 3 of the four don't fit. The ones from the control valve to the ram were labled as ext and ret but they are both identical. I don't know which is which but one is supposed to have a larger radius so that it can cross over the other.

Which hose(ext/ret) connects to the lower port of the control valve and crosses outside and over top of the other one?

Am I supposed to make these hoses work some how or is one of them just plain wrong? I tried to re-radius one of them with out much luck and that is why one appears to be slightly different in the pic.

Next I found that the pump to control valve hoses were wrong. As you can see in the pic the bends are way off on this one. I might be able to make this work but I haven't tried to rebend it yet. Correct me if I'm wrong but I believe this is the pressure hose due to the threaded fittings on each end with the smaller fitting being on the control valve end...

Now the other hose(sorry no pic) I think is the return hose because my old hose had a much larger threaded fitting for the control valve but the pump end just slid over the pump housing tube fitting and was clamped. The "repop" hose that I got has threaded fitting on both ends.

What should be the correct return hose connection at the pump, threaded or slip fit and hose clamped?

I'm almost ready to fire this thing up before the body goes back on and I'd like to know if I can/should some how make the hoses that I have work or are they just too poor of a repop and I should just order a new set from another vendor?

Thanks.

Re: 69 p/s hose help

Greg, It's been awhile since I replaced my hoses but from what I remember you are correct, the return hose slips over the pipe on the tank and clamps tight. Looking at your old hoses I remember the smaller radious one being the inside hose with the larger radious one crossing over top of it. Sorry not much of a help, I'm sure other will chime in.

A hose is a hose is a hose, so they say. As long as the threaded connectors are the same (and I believe they should be) they will work. I think the AIM spells out which hose goes where (supply/return), I know the overhaul manual does. The repops I bought have the same radius, and they will fit. Whether or not it will cost you points in judging, is another thing. I had to pull the PS unit out to get the fittings started because of the weird angle they thread in, but I got them installed.

The low pressure or suction hose is clamped at the pump, but the clamp is not a tower or side screw type clamp as for as I know. I believe the original clamps at that location were a permanent crimp type hose clamp, with the clamp connection like the clamps you see on CV joint boots.

For details on hose and clamp installation see UPC N40, Sheets A2 and A4.

Re: 69 p/s hose help

Well I had my head up my you know what last night but today I see that the return hose will in fact work. I also managed to bend the supply line enough so now I think it will work also.

I however don't feel very comfortable in bending the one control valve to ram line enough to even make it work let alone look right. Best I can think of is to cut, shorten and reflare the "inside" one but that seems extreme.

Micheal how did you go about making yours fit? Did you have to bend them a lot and are the tubes touching where they cross? The "inside" hose must have a lot of flex in the rubber hose portion does it not?

Does anyone know if this is how all these valve to ram repop hoses are made or did I just get two of the same even though they were labled one ext and the other retract?

Chuck, Chuck, Chuck....you read my mind...which is no great accomplishment I might add. I was wondering what type of clamp was on that return hose and that was my next question. I for some reason think it was crimped as well but I'm not really sure. Can someone shed some light on the type of clamp that secures the return hose to the pump? If it was in fact crimped what is the next best one to use? Spring clamp comes to mind because there should be no real preassure there anyways.

Re: 69 p/s hose help

There are pliers made for crimping this type of clamp -- as Chuck mentioned they are used mostly on CV-joint boots nowadays. The challenge is to get the clamp material in the right diameter to work on that hose. Perhaps others have already overcome this obstacle, and will help.

Re: 69 p/s hose help

I got the hoses in a postion where they wouldn't touch. Once they are in the right holes, and in place on the car, you have a little freedom to "tweek" them aroound a little so they don't rub against one another. Then just snug them down.

...Chuck, Chuck, Chuck....you read my mind...which is no great accomplishment I might add. I was wondering what type of clamp was on that return hose and that was my next question...

A guy in your profession was bound to know the purpose of that hose pipe on the back of the PS pump...it's a no-brainer that the hose has to be clamped. That only leaves "What type of clamp?". Plus, the type of clamp is unusual...might as well lead you straight to the complete answer.

Unfortunately, I expect those repro hoses will cost you something in judging...judges will look at the PS valve, hoses and hose positioning for correct configuration. In this case, the configuration of the tube ends is obviously different from the originals.
