Replaced the belts on Hoover WindTunnel U6473-900/brush won't tur

I have replaced the belts on my vacuum but the brush won't turn. The larger belt is turning but the smaller one is not. It is the correct belt for the vacuum but it looks as though it is too big around so it isn't connecting with the brush.

There is a belt tensioner that maybe not contacting the belt when you tilt the handle back, It is either jammed and not moving up and down freely or it is broke. Look down below the belt, there should be a small wheel, that has to contact the belt.

I have a new eureka vacuum AS1101 and the roller brush wont spin. The S belt doesn't look worn. When the clutch is engaged the second smaller toothed belt doesn't run. Are the larger and smaller pulley...


The answer is you small wheel that is burned or melted is a result of having the carpet height setting too low for surface being vacuumed. Because of that, it causes the brush assembly drive to work harder. The smaller of the two wheels has..had a piece of plastic to hold it against the shaft to allow it to turn. It will have melted off and will not spin. The belts and even the other larger wheel will work, but just not engage the smaller and allow the brushes to turn. The part needed does not sell by itself, you would need to purchase the on/off wheel assembly. OEM Part # 84708. It is about $30 on amazon shipped. new-eureka-vacuum-as1101-roller-brush-imoup3n5z40rufpnmkir3rab-3-2.jpg

How do I replace the smaller belt that attaches to the brush


Hello! Follow the steps below to replace the v-belt on your Hoover.

1. Slide flat belt off large pulley.
2. To remove v-belt, slide back of belt over pulley. Then firmly pull on belt and snap it off. Discard used belt.
3. To install new belt (with lettering on outside of belt) slide back of belt over pulley and pull front of belt toward groove next to pulley. Belt will pop into place.
4. Insert brush-roll through belt and position belt in groove on brush-roll.

Hi I have a dirt devil vision. Hose works, but does not vacuuming the floor. Belts are not broken. Larger belt is moving, smaller belt that moves the brushes does not.


hi krueger, sorry for the problems but hers an idea how about turning on the vacuum and put your hand under the part where it sucks uo the dirt off the floor and i guessing you would have a little suction, since the brushes are not moving its going to not pick up as well as it should my guess is that the belts need to be replaced even if one is moving, i would change both belt to be sure and also are you smelling a burning smell if so then that would prove fact to needing new belts, hope this helps, Jamie

Eureka Boss - Belt is not broke but brush will not turn. I have already turned it over - checked belt - and pushed the reset button.


The belt may look fine but they can still be stretched or worn and it won' turn the brush. Try changing the belt and see what it does. You can get Eureka belts here:

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


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.

The brush roller stops turning and I can smell the belt burning, then it will catch and start working normal. I looked under the plate to check the belts and they looked okay and no hang ups of string or...


better to replace both belts the smaller one is stretched out thats whyits slipping ,be sure to clean the old rubber off the motor shaft before replacing the belts.it will cause the new belts to run unevevly and go bad before their time

Brush froze up and keeps breaking belts


I had the same problem but I found that I had replaced belt incorrectly. After placing one end of belt around pully, it has to be run behind the "belt disengager" which looks like a 1/2" wide metal tab just past pulley. After placing belt correctly I had no more belt, burning smell or brush problems.

Brushes won't turn


Sounds like you have broken belt. I had the same thing happen, Got replacement belts, but can't figure out how to get the smaller belt back on. There two larger belts - one on each end of the brushes under the clear plastic covers. On the left side there a single silver metal gear, but nothing to hook up the other end of the small belt to drive the brushes. If you take yours apart let me know how to hook up the smaller belt.

Thanks,
David Wood

Belt Stretched on my Hoover Windtunnel Farrington upright model U6431-900


hi, In order to to replace the V belt the one that turns the brush, One must take off the bigger belt " drive belt" that goes over that hugh wheel towards the back. When a belt gets stretched they will not turn the brush very well. If you have bought replacement belts the bigger belt Drive comes 2 in a package. Then you have your little V belt that helps turn your roller brush over. Yes the belts don't last long on my hoover. For kpatr22101 When you rpelace that V belt it goes over the roller brush into a little groove on the brush and then over a plastic round wheel then you must put on that bigger drive belt that must fit over that hugh wheel towards back and smaller on in front. Yes it is hard to get on. the I hope this helps. Cindy G.
