In November 2 brothers are going to make a cross country run just like their grandfather did 100 years ago.
I posted on the AACA Forum this picture of a Maxwell engine with an aftermarket T water pump. Can anyone identify who made this pump so they can find one like it?
Multiple manufactures made similar design pumps, here is a match for that pump on ebay
Why not rebuild it? If you don't have the know-how, I am sure someone locally can do it for you. That style would probably need a new bushing, a new shaft and pack nut. All can fairly easily be made and installed by someone who is handy with a lathe. A similar design with a pack nut next to the pulley is even easier to rebuild because it doesn't require machining a new nut like yours does.
Forgot to add . . . any pump you find will most likely need a rebuild, so purchasing another pump may not be the answer.
There are so many pumps that all look alike and have similar designs. Bergs for example, being a copy. Ebay has them listed all the time. Be sure any proposed pump purchase has a good pulley and gland packing nut. I love my pump. J.
I'm pretty sure those were sold under the name Blackhawk.
The Maxwell was a thermo syphon design. I would make sure the radiator is in good shape and pitch the pump. That Maxwell is a well built car, and like a T, it has no need for a water pump.
If you must run a water pump due to the radiator age and lack of air to heat exchange, or engine with timing or other issues, then you can buy a new water pump. Same fit at that Model T era old time pump on the Maxwell now.
Here is link for new replacement pump for Model T and will fit like the old one.
Looks like a Blackhawk to me also. They were a good pump from the era. I would not worry about the pack nut but would install new bushings and a stainless steel shaft. I think it's just 1/2 inch shaft. Looking at the photo, looks like a pipe was welded on the inlet at the bottom. I think I would clean it up after removing the welded on section and put a setup like the T's on. Hose, tube, hose. You might have to use a bend in it. A muffler shop should be able to make it up.
