Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

The roller brush will not rotate even after replacing with new belt- the skinny one


Answers :

My roller wouldn't turn and the problem was that the larger flat self propel belt had gotten stretched. I replaced it with a new belt and the roller works great now. So perhaps you need to replace that belt also. Hold it up to a new belt and see if it is significantly larger and you'll know it stretched.
Take out the entire roller brush, you probably have hair and dirt in the bearing end. After you clean the junk out, try it again. If the brush can turn easily, the belt should be able to turn it. Don't use liquid oil, it will get dirt in it and may drip on the carpet. Use some dry graphite, white if possible and clean out most of the excess before putting it back in.

Noise My Dyson DC08 is making a loud, rough, vibration/noise that seems to be coming from the from the rotating brush housing. I replaced the old belt which was several years old and slipping. When I run the motor with the new belt removed the machine sounds normal. The bearings on the rotating brush seem to be running smoothly when turned by hand both when out of the brush holder and when installed in the machine. I can't find anything rubbing on the belt or rotating brush. I applied a bit o

I have a Eureka 4870GZ. It turns on, but the brush roller doesn't move. The belt looks fine. I do have an extra belt and would try replacing the old belt, but I can't get the old one off the motor shaft or the new one on. I called Eureka customer service. The lady said there's supposed to be a small space between the motor shaft and the outside edge of the vacuum where I can slip the old belt off and the new one on. I don't see it. It looks like the motor shaft goes into a recessed place in the

We are trying to replace the belt on the bissell 89q9 model. We purchased belt 8 and got in onto the brush however the brush doesn't spin anymore. Even trying to turn it by hand doesn't work. One end of the brush has a round end to slide in (clear end piece); however the other has a rectangular end to slide in (black end) so we don't even know how it ever turned. Any suggestions?

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t

Hoover Windtunnel U5750-900 Agitator brush is weak. It turns fine if I tilt the vacuum back, but it slows to almost 1/4 speed when it touches carpet, even on the highest carpet setting.

The little metal turning piece that turns the belt is turnable with one's finger when the belt is off, but when we put it all back together and turn on the vacuum, the brush bar does not go around and the burning belt smell returns.
