Info needed: Ford V8 water pump rebuild kits

[Paul Singleton]

A good friend has a 1940 Ford sedan with a 221 engine. He purchased the new reproduction water pumps that use a more modern seal and bearing instead of the bronze bushing in the stock pumps. I did note that the shaft size in the original pumps are 1/2” and the new pumps appear to be 5/8”. You could probably bore the original double pulley to fit the reproduction pump.

Thanks Paul, that’s very helpful information. I think I’ll get the pumps off the engine and start measuring up.

FYI guys the riveted carrier uses a double sheave water pump that has a sealed bearing in it. In other words, not a bushed pump.
I would like to know what the bearing number is if someone knows.

I actually have two of the Mac's rebuild kits out in the shed somewhere. I'll check them for numbers if I can find them.

I spoke to Belcher Engineering in the UK today, and unfortunately the repair kits have been on back order for over a year, so no chance of getting a kit anytime soon. They said that they can rebuild the pumps by adapting Jeep rebuild kits, or by adapting one of the newer design of pumps. The latter is likely to be over £100 per pump.

Has anyone had previous experience using Jeep rebuild kits?

At work we made the mistake of sending a pair of carrier pumps in for rebuild without asking for an estimate. They came back at over $700 for the pair. £100 each does not seem that bad.

I believe the original seals with the rubber, carbon disc and spring were the same as a Jeep. The Jeep water pump bearing is somewhat larger than the V8 bearing. The part numbers of the two bearings would help. Anyone?
