I'm also going to rebuild my pump. I am contemplating powder coating the unit. My question is do you think doing the inside and outside would hurt anything? I would hope the smoother it is the better the flow would be.

Picture came through great. I'm going to be on the lookout for a spare and then my dad and I can fight over who pays for it. I paid for the kit so he's up to bat.

The original water pump on my engine had been welded in the same location. I had planned on using it but I found a good one at Hershey. I plan to do as you were going to and build it up as a spare.
I don't seem to be able to post a picture on this reply.

And I agree with Gary... the spare pump we have didn't get used for a reason. Feels like junk to me.

Mike, since the spare pump rebuild was a convenience idea to simply make the swap quicker, rebuilding the exsisting pump is probably what we will do unless I find another decent pump housing. I've never paid attention so I don't know if they are unobtainable?

Sadly this is a mess. I was a welder for 30 years in a major public utility company in California. This can be repaired but its going to be very difficult. This newly found crack will require grinding out. Then clamped back to the original position. Then welded in. Cast iron is tuff to weld so most times its braised. But new roda are available today. Once this is welded you will require machining to straighten out the seals so they are inline with the shaft. May be best to locate another housing. Its a gamblers choice. Ask yourself if you were on the dark side of the moon... On a sunday night after 6 pm what would you do to get home....

I see the large crack, the braze repair and some JB Weld over the brazing repair which tells me the braze repair wasn't good. I think you are better off looking for a new housing.

Well, before doing anything else I figured I would sand blast the spare pump casting to make sure there was no other hidden issues. Voila! Big crack. Should I see about getting this welded up or is it junk?

The machine work is regarding the seals. I will email you the instructions.

Thanks Jim!
The seals in the picture where in the box with the old pump, I didn't take the rest of the stuff out of new kit but will go check and give what you are suggesting a try!

Also, I seem to recall there is some machine work that is necessary to make the new shaft and impeller work? There were no instructions with the kit, so maybe I'm imagining that.

If the section was welded back on properly it should be fine. Check it by putting the bearings and shaft in and tighten down the cover. If the shaft spins freely they you are fine. If the shaft binds then the piece was welded back on at an angle. If the misalignment is not too bad then it can be corrected with some machining.

The other key to rebuilding the water pump is making sure the seal surfaces are lapped in properly. It looks like you have the modern cartridge seals. Did you also get the ceramic seats? If so make sure they are installed 90 degrees to the shaft.

We have our kit now. While rummaging through my dad's Cord parts I found an old pump and got the bright idea that I should rebuild that one and have it ready to swap out. When I got it home and started looking at it I'm thinking I see why it didn't get used. It looks like the shaft housing has been welded back on. Rethinking my plans. See pictures. Thoughts?

Thanks for all the feedback. We decided to order one. Our car runs with the temp gauge pegged at the top, but never actually overheats. It has the new heads on it. I need to put a heat gun on it but I'm wondering about that temp gauge. I've never been a fan of those King Sealy sort of gauges.

Thank you for the pictures Terry, I was wondering what an original impeller looked like and what metal it is. It appears from your picture that the impeller is cast iron, is that correct? I received an extra water pump with the Westchester that I purchased earlier this year and it had a tag on it that said "maybe rebuilt". Looking inside the shaft is very shiny and the impeller looks to be made of brass however I only count 8 vanes. If the original impeller was cast iron then maybe there is hope that my extra water pump is indeed rebuilt. Of course who knows when.

For those that have not found it yet here is the website address, it does not seem to pop up near the top of searches, at least the ones I have done:

I had no idea Henry's daughter was still running and keeping his business open for sales. I still need to go up there just to enjoy looking at the Henry shop. I admired Henry and his work for over 45 years.

Henry designed the impeller to be more efficient. It has more blades than the original, ten versus eight. I think I need one now too.

You and I think a lot alike. As I mentioned in the other string I just bought two of them. The Westchester that I recently bought has a water pump leak and I figured having an extra one in case the Phaeton does the same would be a good idea. As you say, how long will they be available. I have not installed mine yet but there are one or two posts on the AACA forum that recommend the kit, here is a link:
forums.aaca.org/topic/313235-812-waterpump-rebuild-who/

One person said the car ran cooler after installing the kit. I am looking forward to installing one to find out.

While buying the fake harness plug from Henry's Portz daughter I couldn't help but notice the very nice stainless shaft and new impeller kit she is selling for the water pump. Our car had its pump rebuilt in 1966 and seems to be functioning well, but I'm wondering if I should take advantage of the parts while they are available? I'm a sucker for shiny new parts that might become unavailable one day.

Does anyone have any feedback?
