Having problems with your Hoover U6630-900 WindTunnel Bagless Upright Vacuum ?

How do you adjust the tension of the v-belt on the u6630-900

\015 I am replacing both belts on my vacuum cleaner but the v-belt is still a little loose and I am trying to adjust the tension if at all possible. I am lost at to how to take the hood assembly cover off. Please Help if possible.\015

Answers :

Hi! I'm not so familiar with this model, but I believe the V-belt is only under tension when the brush roll  control is in the "HARD" or "OFF" position. I'm not sure what the exact mechanism is, but I suspect that moving the control to the "ON" position is what places the belt under the correct tension and thus drives the roller.  Please let me know if I'm right!\015\012As for your other point, not sure what you mean by the "hood assembly cover" or why you might want to take it off. If you can clarify, I'll help if I can.
Once you get the screws out, there are very small plastic clips molded into the hood that clamp to the clear plastic. these are located on the outer edges in about the middle of the sides. get a bright light and you will see it will be obvious.

How is the V-belt tension adjusted (Hoover Model U6439-900)or how do I know if the tension is correct? There seems to be a lot of "play" in the belt and I'm wondering if that is the reason the brush roll only turns as the wheels turn, regardless of the carpet height setting. And yes, the brush roll is set for carpet, not hard floor. Or is the cause of the problem something other than the V-belt? A new flat belt was installed when the machine was professionally serviced so I assume (?) that was a


The V-Belt is not adjustable. There are two ways the belt has no tension: (1) when the handle is upright, a mechanical lever takes the drive tension off the belt, and (2) the brush roll lever setting you described.

Brush Roll belt stops turning durring vacuuming on WindTunnel self-propelled, v belt is a little loose with handle down. Tensioning roll is engaged OK, but fully at the end of its travel. Replaced belts flat and v, but still stops turning even on high carpet setting when vacuuming. Carpet setting and height adjustment appears to be working OK, roll is clean and turns easily when out. Also turns easily until it engages the carpet. Self propel function works just fine.

I have a Miele S1721 Powerhouse upright vacuum. When the belt broke I took it into the shop (because when i tried to replace the belt, the tension was so tight I couldn't get it back together!!). When I got it home I DISCOVERED THAT THE HEIGHT ADJUSTMENT DIDN'T WORK anymore. It seems like it's set really hight, because it no longer contacts and brushes the carpet. So it's now useless. I went back to the shop and the tech denied that there was anything wrong. (I didn't have the vac with me). No

Belt keeps sliding over on the roller bar and rubbing on plastic parts. Belt is a "U" belt and I am told it should be a "R" belt. Sears sold me a "U" so I will try and find the R tomorrow.

Chain tensioner Is it possible to change the chain tensioner of the Husqvarna 240 to a tool less chain tensioner or at least to the chain tensioner where the adjustment screw is accessed from the side not from the front. The problem is that there is a little plastic part that breaks rendering the chain tensioner useless. I have changed it twice and it keeps breaking. To change it you have to change the whole part that covers the break and chain mechanism.

Right now it just snags and gets caught underneath the material and bunches up into a big ball. There is a lot of thread inside the bobbin case that came out of the bobbin and has to be cut out to free the material. How do I fix this mess. I am a novice at this.

Put on a new beater brush belt that I bought from Sears as detailed on the plate on the vacuum. It immediately snapped. Is there a diagram for the routing for the belt (there is a drive spindle and a tensioner)? Thanks.


I would first check to see if the beater brush is turning freely. You should be able to turn it by hand. If you can not, remove it from the vacuum and clean any debris on the brush and especially on the ends that hold it in place.\015\012Some WD40 ... Kenmore Whispertone 29512 Vacuum
