20-year-old Shop-Vac

I gotta 20-year-old Shop-Vac 8-gal. that's seen lots
of service in my little basement workshop.

When I run it now, it makes horrible screaming-gurgling
noises. I have disassembled: I can't see them, but it
appears to be bad motor bearings.

Are such units repairable? Any way to nurse the unit thru
another year or 2? Can't afford to buy a new one ...


Maybe you can pull the rotor and replace bearings--depends on design.
Unfortunately, imo by that time there's usually too much wear or the
brushes have rubbed to the point of being beyond much hope.
