Thread: 1950 Delahaye Water Pump

Tweet

I'm not sure if I'm putting this in the right room or not, but I'm sure Mr. Mustang will fix it if not.

I have a 1950 Dehahaye water pump in my shop to be rebuilt. This is the first one of these I have ever worked on, and I was wondering if anyone out there either knows of someone that owns one of these cars, or maybe has a repair manual for one. I have done a few searches thru google and yahoo, but nothing helped. Can anyone help?

I can't help you with the waterpump issue, but that sure is one wild and crazy avatar that you have now. Did you do that yourself?

I called Superior Pump here in Phoenix and he has no parts at all for a Delahaye. He always has several ads in Hemmings and purports to have parts for anything. I'd be thinkin' cutting/welding/machining to adapt a Chevy seal, bearing and impeller to the delahaye housing.

Thank you for doing that. This pump looks nothing like any water pump you've ever seen before. I have a picture of it I can post. I would love to be able to adapt something, but this is going on a $500,000.00 restoration project and it has to be absolutely perfect, and original. So now you see what I'm up against.

Thank you, I had it done by a friend.

Thank you again for the lead, Richard, I will contact him Monday. I guess my google and yahoo search wasn't extensive enough. I'm sure that guy will be able to help.

Some of the older cars had water pumps that would disassemble easily so that new bearings and packing glands could be installed.

Any chance that the Delahaye pump is the same?

If so, a bearing house may be able to help you out with the bearings and packing gland material.

Take a peek at the picture above. I have this ready to go back together, but need clearance specs. I've been rebuilding parts like this for a good many years, but this was the first one of these that I came across. The worst part of this one was it came to me in pieces, and I had to figure out how it went back together, and have it come out perfect. It takes about 4 hours just to remove it from the car, so I don't want the customer to have any troubles with it. I'll be contacting Richard Gorman on Monday.

That's quite a pump.

I'm guessing there's not too many oil fields in your neck of the woods, but oil field supply houses are also very good places to find stuff for pumps etc.
A lot of oil field equipment dates back quite a ways and there are a lot of different size pumps used by that industry.
There may be oil field pump supply sources on the Internet.

I'm sure you've thought about Grainger and McMaster-Carr.

Another place that may be able to help is a farm supply house.

Might check with a tractor store as well.
Lots of hydraulics on those and finding parts for pre-1950 tractors is easy.
A lot of these old tractors are still used on farms regardless of the farm size.

Another alternative if needed would be to contact the Nethercutt Collection. http://www.nethercuttcollection.org/index2.html They have an extensive document collection, and do their own restorations of cars in this league, so may also be a resource.

Techinspector, I called the guy you suggested and he referred me to another guy, who referred me to another guy, well, I ended up calling a total of 7 different people before I got someong that was able to help. It's a good thing I found him, cause my next call was going to have to be Switzerland. I was able to get exactly what I needed, and the pump is on it's way back to the customer. It's funny, that a vehicle that will end up being a $1M restoration has such a rather un-impressive part. This water pump looks like something that belongs on a washing machine. Anyway, thank you for the referral, I appreciate it. I only wish the problem was with the valve springs.

As scarey as that sounds ..............I did enjoy your shot at the cheese eating surrender monkeys!

It makes perfect sense. As it stands, our customer base goes around the world, and I'm plenty busy being a one man shop and all, but more work is always a good thing. As a side note, I just got an "atta-boy" from the owner of a 1934 Lincoln Model K V12 had won the last Pebble Beach Show. I rebuilt the fuel pump, water pump, and oil pump on it. Good job, me. Thanks.
