Having problems with your Vacuums ?

Rainbow SE Motor Brushes Arcing

\015 Dear Sir,I have a Rainbow SE and I noticed that is was giving of a bit of a burning smell when running. ( same problem that you address here https://www.fixya.com/secure/support/t475735-burning_smell)I have disassembled and the brushes are arcing when the motor is turned on. When I spin the armature by hand I can feel a slight amount of vibration which make me think one of the motor bearings is shot so I was going to replace those but my question is: How do I test the armature to make sure that is not the problem? Do I just test each spot on the armature with a multi meter looking for continuity?The brushes look good they are still about an inch long.Thanks\015

Not exactly a blow gun. Convertible blower/vac - Sears Craftsman. Wire broke off ONE brush in the motor. Paid about $90 for the vac - Sears lists the WHOLE motor as one part - $88. Have requested brushes (they are provided with a lot of my 'cheap' Harbor Freight tools) but no go. Just get the canned reply - buy the whole motor. Actually got it working again... CAREFULLY drilled and tapped a 4-40 screw into the brush and soldered the lead to that... Always a way, isn't there?

Hoover WindTunnel S3765. The motor spins and the belt turns when I turn the brushes on, and the brushes will spin. The problem is that when I do this on carpet, the brushes stop spinning. As soon as I pull the "head" off the carpet, the brushes spin again. It's almost as if the vacuum suction is too great. I took the head apart and watched the motor turn the metal spindle that the belt rests on, and the belt turns as well.

My bissell model 18Z6 has developed a loud noise and vibration when the brush is running. I have removed the brush assy and cleaned all the hair, etc but still the noise. I ran the brush motor with the belt disconnected and all seemed ok, but of course there was no load on the motor. I suspect a problem with the brush assy bearings or axle or both but I hate to just throw parts at the problem. any suggestions would be greatly appreciated.
