My husband thinks the bearings went out. Mid board, the blade suddenly stopped, but the motor still hums. No smoke.

Bearings are a pretty simple fix if that is what it is. Certainly a possibility given the age of the motor and the fact that it has not been used in a very long time. Try taking off the belt and spinning the motor by hand, as that will give you a pretty good indication if they are seized or not. Since you have already basically written the motor off, it certainly won’t hurt anything to open it up and see what is going on. Give it a good cleaning out, check the bearings, clean up the contacts on the centrifugal switch, etc… also, grab a multimeter and test the capacitor while you are at it. Can’t tell from the data plate, but does it have one (start) or two (start + run) capacitors?

Chances are, you are looking at just a few dollars to fix, rather than several hundred to replace.

Cheers,
