Belt tensioner overheated and doesn't keep belt tight enough

\015 I have a feeling the belt tensioner overheated and lost its 'tension'on mine.\015\012 New belts slip as soon as roller brush hits the carpet.\302\240 What I would like to know is whether the tensioner assembly is available to buy, it doesn't appear so on eureka's site. or\302\240 How Can I find/measure and buy a shorter rubber belt to use on this after removing the tensioner assembly altogether, therefore having a normal sweeper without the roller switch.\015

Answers :

Looking at the owner manual, there is no tensioner assembly.
If the motor is fixed in place and not loose, then you either have the wrong belt, or the brush roller is not properly installed, or the brush roller is worn out where the belt goes around the brush roller.

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. What keeps the belt other than tension from sliding onn the roller bar? Could it be that just the wrong belt could cause this??

My hoover Wind Tunnel vacuum cleaner's motor spindle keeps overheating. Because of the high temperature, it keeps burning through belts (the big, wide ones).

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

We just used our bissell pro heat 25A3/64D9 series and the top half of the handle is not secure. Infact it flies off in my hand as im cleaning the carpet and it almost hit me in the face!!!

It looks like a major design flaw.

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

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.

Windtunnel belt I have a new Hoover Windtunnel canister. The belt keeps coming off.
