Topic tags/keywords: dust collector delta 50-775 motor noise

Hoping someone here may have run into a similar problem and can help identify a solution.

My Delta dust collector has always been trouble-free, but today when I fired it up, I heard a high-pitched squeal when the motor came up to full speed. I am thinking it might be bearings but I’m not sure. I pulled the motor and didn’t notice any play in the shaft, but who knows? Again, the sound only happens at full speed. Any advice is appreciated. Thanks!

Hi John:

If it’s a bearing, you’ll know pretty soon; ie. it’s gonna get worse in a hurry. I have 4 1200 cfm Delta collectors and the only problem I have had is that they all had to be switched to 220V in order to start.

Maybe a bit of debris is jambed in by the impellor and is rubbing when the collector is running ??

Thanks Dwight, I pulled the motor and blew everything out, although it didn’t look that bad in there. Reassembled and squeal is gone, but now I think I hear a slight rattling that wasn’t there before. Might be phantom noises at this point. You know how it is when you’re chasing down an engine tick, etc. We’ll see what happens.

Probably got a wad of wood in there.
