I'm looking for a replacement motor for our Panasonic MC-663 Jet-Flo. The motor says Matsushita 2V-531N on it. It needs new bearings I think, and the fan housing is riveted on and will be a real pain to disassemble. If anyone has one in good shape, let me know.

Finding an original replacement will be tough. You would have to show me the fan opening but if those motors are made like their same year canister motors they are quite repairable. The fan should be retained by a hex nut and flat washer. I would like to see if there is a lip on the fan housing you can get the blade of a screwdriver on so you can tap tap the fan housing off. The images make the motor appear to be single stage. is that the case? You will need a press to get the bearings out, especially the upper one can be stubborn but they are repairable. I had some early 1980s motors rebuilt by a local vac shop and laughed when searching for the bearings. They were a popular front wheel bearing for quads so there was a huge selection from every manufacturer. I went with bearings from the Japanese company Nachi. They are high quality and probably what Panasonic used originally.
