Question about Hoover U6630-900 WindTunnel Bagless Upright Vacuum

1 Answer

I have a Hoover Windtunnel U 6439-900. The agitator brush will not turn. I installed 2 new belts, # 38528034, and # 38528-035 There is so much slack in belt # 3852034 (brush drive) that it cannot grip the brush. There does not seem to be any adjustment to take up the slack. I've put in new belts twice now & cannot get brush to rotate or tighten the belt to the brush.

There is an idler pulley that takes up the slack in the V belt when you pull the handle back to vacuum. Make sure it is engaging properly and the V belt is installed correctly.

SOURCE: Replace the belt

Take off the bottom plate, put the new belt on the motor shaft first, then stretch it to go over the pulley, it is hard, but it will stretch to go over it.

Brush won't turn and self propel doesn't work (by 2 users)
Posted by brucelk on May 24, 2008
I have replaced both the v-belt and the larger belt with Hoover brand belts and the brushes still don't turn properly and the self-propel function doesn't work. It seems that when I lower the handle all the way down toward the floor it works fine, but no one can vacuum this way. Is there an adjustment to belts to tighten them up? Otherwise I have to get it in to the only repair shop in town which is an hour's drive.X

OK
1 Other User Has the Same Problem Comment by chartsell, posted on May 29, 2008 I have replaced both the belts as well. I have tightened the screws as someone else as suggested. The brush still will not turn unless you lower the handle almost to the ground. Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Hoover U6437-900 / U6439-900 Windtunnel Vacuum. It is not so much the belts, the 2 belts are only part of the solution. The average belt change is every 4 to 6 months as a rule and to change them @ the same time. The Hoover Self-Propelled works on when the handle is lower to a comfortable position then the self-propelled drive may just need and adjustment. There is a self-propelled rod that controls the self-propelled feature and it either needs adjustment or replacement or the part that hold it may be broken but either one can be fixed. So feel free to contact your local vacuum cleaner dealer with questions. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

SOURCE: Replace the belt

Once the bottom plate has been removed, the motor shaft is silver, but hard to see. hook the new belt on it first. then start rolling on the top of the large black pulley to install.

Hoover windtunnel


Hello--How about the Flat belt? That would be my next step...then, if it's still not turning, perhaps the beater/agitator bar's bearings are the culprit...calling for a new beater bar /agitator.

Hope this helps--

Sounds like you should do two things: 1- Remove and clean the beater brush of all debris as best you can. At the end of the brush you will see a hard rubber piece, at both ends, that holds it in place in the body of the vacuum. Add some WD40 between the brush and these pieces and turn until they move freely. 2- When you reassemble, put a new belt on.
This should be all you need to do. If you find this information to be of help, I would appreciate a Thumbs Up from you. Be well, Paul

Describe how to replace belt on hoover windtunnel bagless


If you turn the vacuum so the bottom is facing up you will see the base plate that covers the roller brush. There will be four screws (usually phillips head), remove the screws and the base plate will lift off. You now have access to the roller brush and belt. Lift the roller brush up and remove the old belt. Place one end of the new belt over the motor shaft and the other end over the roller brush and put the roller brush back in place. Now simply replace the base plate and you're done! This models requires Hoover belt # 38528033 (single) or Hoover belt #40201160 (2 pack). You can get this belt at www.vacbelts.com.

Hoover wind tunnel 2 bagless vacuum not working


Place handle in low position and turn cleaner over so bottom side is up.
Remove the 4 screws in bottom plate and lift off.
Look on the left side of the agitator brush. You should see the belt there. Remove agitator brush roll and used belt.
Discard belt.
With lettering on outside of belt, slide new belt over motor pulley.
Insert agitator though belt and place belt in belt guide on agitator.
Grasp agitator firmly and fit it onto position by first sliding end opposite the belt into the rectangular slot on side of cleaner.Pull other side of agitator into place
Turn agitator making sure belt is not pinched between agitator and agitator shield.
If this does not take care of your problem, then check your filters for dirt and your entire vacuum for blockages. Both filters do come out. If you can't get a new filter right away you can gently clean the paper filter and remove a lot of dirt. (I recommend outside)! The other filter is washable.
Make sure it is well dried before replacing.
Good luck.

BELTS ON WINDTUNNEL VACUUMS


Greetings from GoVacuum,

Here's an instructional video that we made showing how to change the belt on a Hoover Windtunnel upright. If your model is not a self propelled model, basically follow the same insturctions, expect instead of placing the belt over the pulley, just put the belt through the roller brush, and stretch the roller brush back into the agitator housing.
Please feel free to send me an email if you have any other questions. My email address is chris.jones@govacuum.com.

Thanks,

Chris Jones
