I have a 2000-ish vintage Delta 1.5 hp (50-850) bag-type dust collector that I changed to an aftermarket pleated cartridge filter. Recently it's been sounding like I've got a bad bearing -- runs normally at full speed, but when it coasts down, it gets to a certain rpm then I get a lot of noise and vibration.
The impeller on this unit mounts directly to the motor shaft -- there are no bearings outside the motor, and there is no parts breakdown for the motor in the manual, it's just a "unit". Sticker on the motor shown, don't think that really informs much.
I've replaced bearings on planers, jointers, and lathes, both those were all external to the electric motor, I've never disassembled an large electric motor (changing brushes is about all I've ever done). I'm OK with DIY repair, but I also don't mind just taking the motor to a shop to have this done, would likely happen a lot faster.
Looking for suggestions on whether to DIY or have a shop do it. I'm assuming this is a common repair.
Thanks.
Dave
