Hi Norm--thanks for the welcome. I appreciate the ideas/response! I'm realizing I didn't focus on the shaft details enough... Sorry for this. I attached a couple more pictures in this post. Attached '0052' displays shaft I'm attempting to fit pump to. '0054' is the new motor shaft. They're very different shafts.
Length is greater on the new motor shaft. The new shaft also has an indented notch... The old shaft has a key that protrudes. Hopefully the pictures do better at explaining details as I don't know the terms well. To me, it looks like the shaft diameter comes out of the case the same diameter (haven't measured this yet to confirm), but is is milled completely different. I have no experience cutting shafts, but cutting everything around the key seems like a lot of dremel work. This is why I was considering the next steps of swapping shafts... They're basically the same motor except shaft. Bummer if this isn't an option.
I suppose I can hunt down a pump that fits the new shaft? Or, just work on the broken motor... Piston is seized on old one. Likely can use the new to troubleshoot/replace jug/piston in new. I'm a "two is one, one is none" kind of guy. But I had one (broke it), bought one, and now have none! lol. Brainstorming options. Thanks for reply.
