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.

Hi my proheat bissell 7901 stopped pumping water to the floor, but it pumps water from the hand hose. I read the manual and followed how to check belt and the flat belt on right side of shampooer is fine and I turned on and it turns and so do the brushes at the bottom of the machine.

I have two old identical 5842's that I use in the garage and around the house. The belt broke on one so I bought a bag of 2 genuine Eurika "U" belts, which is the correct belt for this vacuum. They were obviously smaller than the original belt because they were not stretched out. When I put the new belt on it lasted about 20 minutes and then came off. I put it back on and ran the vacuum with the cover off to see what was wrong. Everything looked fine except the belt rides to the outside edge of

Floor Attachment I took off my floor attachment, but now the belt seems to be off and I can't seem to get it back on right. I can't use the attachment and I don't know why it's so hard to figure this out. They say, just turn it to belt off, but when i turn it it lift's it up and can't line up with the belt off label.

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.

On our Hoover U6445-900 (Mach 6.9) we replaced the small belt that goes to beater brushes in front of unit. Upon starting, the Hoover quickly got hot and smoky.
