Hi there, I recently acquired and restored for the most part, A mid 1930s Hoover model 25. It has the original wheels, bumper, and rubber handle grip which is brittle. It has a factory original bag and cord from a hoover model 28 which are both in mint condition, but it's close enough.
Unfortunately, since I tried to service the motor and lubricate it to spin freely, whenever I run the machine, the motor tends to smoke a lot, within 10 or so seconds. The thing is that, even though it seems that the vacuum runs at pretty much normal speed and the brush roll spins freely without issues, the motor still smokes. Even when I unhook the belt from the fan shaft and run the machine for more than a few moments, the motor still smokes, and I immediately notice a burning electrical smell.
It's a shame because I serviced the motor by lubricating and oiling the armature shafts and bushings in each bearing. Though the armature and fan spin freely, the motor still smokes, so I now think that somehow the windings in the armature shorted out. If that's the case, I don't know where to get a replacement armature, which has intact windings. Either I'll end up finding a spare hoover 25 motor that runs good, or I'll have to get the entire armature rewound. I don't know if someone has a spare hoover 25 motor that runs good, that can be for parts. I'm not really sure what the best thing to do is at this point?
