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.

I've recently managed to get my hands on one of these (in NZ so the 230v version). Mine has a pretty rough sounding motor too, I haven't had a chance to pull it apart yet but I'd been hoping simply refreshing the lubrication on the bearings would see mine right for now. After I've cleaned it up I'm not likely to use it much (getting spare parts for older machines in NZ can be a pain ,and international shipping can be cost prohibitive), so unlike me it's probably just gonna sit around & look pretty! lol

I am digging desperately for one. I so want to try one.

Motors rarely ever go bad unless it fails so catastrophically that the windings short out. It's 96.9% of the time dry bearings or worn bearings.
This yummy blue goo is what you want to feed your vacuum cleaner motor. It's way overkill for a small motor but it ensures it lasts permanently in such a small application (these are made for industrial machinery motors that fill half a room) and it makes a huge difference.

I have old brown grease in a jar from the 60s. Good tip.

That is ok if you have shield bearings and can remove the metal shields. If you have sealed bearings, many do, then you cannot lubricate them. You remove and replace them.

Yeah, repackable bearings are terrific!

There is good and bad. Shield bearings are not dust tight. Bearings with lip seals are. And while you can't repack a sealed bearing, once you have the bearing out I kind of don't see the point of repacking a bearing that is worn. Bearings of the size used in most vacuum motors are pretty inexpensive. Even good ones. Once I have a bearing out on the bench I see little value reusing it. I just toss them and replace them with a good quality ( Nachi, SKF ) sealed bearing.
