Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum

1 Answer

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

Roller brush was turning sporadically so I removed the bottom plate to see if belt(s) were broken only to find they are both fine. Could the roller brush belt be stretched? If so how can I tell?
Also cant figure out how to remove the drive belt. It seems hard to get to the pulley behind the wheel. From the looks of the configuration I have to remove the drive belt before I can replace the roller brush belt correct?
Any and all info for checking stretched belt and how to replace both belts would be great.
Thanks

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.

If the brush roller was removed, it may have been reinstalled incorrectly, causing it to bind on the bottom plate.

I'm getting no suction and the brushes are not rotating


Hello! If you are using the cleaner on carpet, it is necessary for the brushes to rotate to assist the motor with maximum pick up. If your brushes are not spinning check the belt to make sure it isn't broken or stretched. The belt will need replacing about once a year. Below are steps for checking the belt on your U5399-900.


1. Place handle in low position and turn cleaner over so bottom side is up.
2. Remove the 4 screws. Lift off bottom plate.
3. Inspect the belt for rips and tears. If it is damaged in any way, broken or stretched replace the belt

This unit takes belt 38528033. Be sure you replace belt with genuine Hoover parts. Here is a link where you may go to order a replacement belt.

Hoover windtunnel vacum..belt is rotating..brush is not..plus belt keep coming off


More than likely, there is hair or fibres caught up in the bearings binding them. There are usually 2 screws you can remove on the bottom of the vaccume that allow you to remove the plate. The back part of the plate usually locks in with tabs. Remove the plate, then pull out the brush. The bearing will come out of slots. Remove the bearings, and more than likely you will find hair or fibers wrapped around the shaft on each end of the roller. Remove the material, reinstall the bearings, roller and plate and you should be good to go! :)

Vaccum not turning or sucking


Hello,

It definitely sounds like your belt is broken. If something gets vacuumed up into the brushes, and prevents the brushes from spinning, the motor will continue to try and spin the belt and the brush, but since the brushes can't spin, this will burn right through most belts.

Especially since you mentioned a sock being sucked up, and the roller brush not spinning, this is a tell tale sign of your belt needing replacing.

Here's what you'll need to complete this repair:

- Phillips Head Screw Driver
- Hoover Windtunnel Replacement Belt, Non-Self Propelled, Hoover Part # 38528033
- Depending on how long the sock was stuck in the brush, you may need a new roller brush as well. The roller brush for your model is Hoover Part # 48414110. Here's a direct link for the roller brush for your vacuum on our website:
http://www.govacuum.com/generic-hoover-windtunnel-tempo-fusion-upright-12-inch-replacement-roller-brush-hoover-part-number-4.html

If you have the Hoover Tempo Widepath vacuum that you listed the repair under, then here's a direct link back to our website, govacuum dot com, to the exact belt for your Hoover Tempo:
http://www.govacuum.com/agbelhoovpar9.html

Now, once you have a new belt, this repair is pretty straight forward. I'll explain step by step what you'll need to do to change the belt.

Step 1. Make sure your vacuum cleaner is unplugged. The easiest way to change the belt in your vacuum is to turn the machine upside down, so the handle is on the ground holding it up, then lean the vacuum over a counter top or work bench.

Step 2. Remove the bottom plate of your vacuum cleaner. You'll see on the bottom of the vacuum 4 screws that are located on each corner of the brush, remove all 4 screws, and lift up on the bottom plate that covers the roller brush.

Step 3. After removing the bottom plate, you should now be able to access the roller brush completely, and you'll probably also notice that the belt on the right side of the roller brush is broken. You may just remove the broken belt completely and throw it away. Lift straight up on the roller brush itself to remove it from the vacuum.

Step 4. Test the roller brush. After something gets stuck in the brushes, and it causes the belt to burn, there's also a good possibility that your roller brush may need replacing as well. Also the roller brush will wear down over time, and the brushes will wear down as well, greatly reducing the cleaning ability of your vacuum. You'll want to test your roller brush, to ensure that it spins freely. If it doesn't, then as you install the new belt, it's possible it could also break immediately. To test the roller brush, remove it completely from the vacuum. Holding just the end caps of the bar with your fingertips, try to spin the brush in your hands using your thumbs. This is how it should look when you test your brush (the roller brush is to a different machine, but testing it will work the same):

3a76171.jpg
The roller brush should spin at least 3 or 4 times in your hands on each spin. If the brush will not spin at all, or you feel some resistance when spinning it, then you'll probably want to go ahead and replace the roller brush as well at this point.

Step 5. Once you have your new belt, and new roller brush (if needed), it's time to install them. First wrap one side of the belt over the metal motor pulley in the back of the vacuum, opposite the roller brush. Now after you have one side of the belt wrapped around this metal pin, put the roller brush through the other end of the belt. Using the roller brush as leverage, stretch the belt with the roller brush inside of it back into the roller brush tray. You'll notice that on the left bearing cap on the end of the roller brush, there's a little rectangular shaped notch. Make sure that the rectangular notch is vertical, and slide this end into the agitator housing first, then fit the other side (circular notch) into the housing. With a little bit of elbow grease, you'll be able to stretch the brush with the belt back into place.

Step 6. Test the belt and the brush before putting the bottom plate back on. To make sure that belt and brush are properly installed, pull the belt forward towards the brush, and make sure that the brush spins while you're pulling the belt. If the brush does not spin, then either the belt is pinched underneath of the roller brush, or the brush is bad / installed incorrectly. Make sure that the brush spins freely before reinstalling the bottom the plate, otherwise the belt will burn and break again as soon as you turn on the vacuum.

Step 7. Reinstall the bottom plate, and screw down the four screws. Now you can turn the vacuum on, and make sure that the brush is spinning. If the brush is not spinning, repeat the steps above to make sure that the belt and brush were put in correctly.

That should fix your problem. Ideally you should change your belt at least once a year. Even if the belt doesn't break, it will stretch out. When the belt is stretched out, it will not pick up as well as a new belt will.

If you have any problems, or questions about how to do it, please feel free to use the Clarification Request here on the Fixya repair page, and I'll be more then happy to answer any follow questions for you.

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.

Putting on a belt on a vacuum


Greetings from GoVacuum.com,

Replacing a Belt on an Upright vacuum can vary from model to model, but it is basically going to be the same for most upright models.

First you will need to access the belt. Most upright vacuums this is done by turning the machine upside down, and most you'll need to remove the bottom plate by unscrewing (usually 4) screws that hold the plate on. You should see screws that are closest to the actual roller brush, simply remove these screws, and take the bottom plate off. If the machine is a Eureka, or Kenmore, the top agitator housing will be removed from the top of the vacuum, not the bottom.

Once you have removed the bottom plate, or top agitator housing, you should be able to see the belt (or broken belt) along with the roller brush. Remove the broken belt. Make sure that you purchase the correct belt by taking the make, and the model number (located on the back or bottom of the machine). Please note that a broken belt may be 4-5 inches longer then a new belt, as they stretch a lot before they finally break.

Once you have the new belt, you will need to remove the roller brush. Pay attention to how the roller brush fits into the agitator housing, usually there will be fittings on the end of the roller that have to be put in a specific place, or in a certain way to work right. After the roller brush is taken out of the machine, you will need to wrap one end of the belt around a metal pulley on the opposite side of the roller brush. Most pulleys are located where the main housing (handle part) of the vacuum meet the the agitator (floor part) part of the machine. Anyways, wrap one end of the belt around the pulley, and then put the roller brush through the other end of the belt. This is where you'll need to put some elbow grease into it. You'll need to stretch the roller brush and belt so that the brush and belt are stretched back to the place where you took the roller brush out of the vacuum.

Once you have replaced the roller brush with a new belt around it, pull the belt a few times to make sure that the brush spins while you are pulling it, to ensure that the belt is not pinched, and is spinning freely.

I hope this helps. Here's a video showing how to replace the belt on a Hoover Windtunnel Self Propelled model; Feel free to email me if you'd like to send me the model number of your vacuum, this way I can be a little more specific, and give you part numbers. I have all belts for all vacuums in stock. Email; chris.jones@govacuum.com. 1-866-468-2288.

I have a Hoover WindTunnel Farrington Upright Model U6431-900
it has worked flawlessly until last week. The roller brush has stopped turning and I believe it is the belt that has broken but I am not sure how to remove the cover to inspect it and replace the belt if that is the problem. Please inform me how to perform the operation and what I should I look for? Is there a site with a diagram on how to replace said parts? Thanks for any and all helpful info that you can supply me with. Larry

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Normally there are either screws, clips or levers that would remove the bottom plate or id that does not work then the top cover will come off and that will expose the belt. Once that is off and the belt is exposed then cut off the old belt and then lift up the brushroll on the pulley end and install the new belt around the pulley end and re-install the brushroll. Then use a belt puller or a screwdriver with a bent right or left end to stretch the belt onto the motor pulley and then track the belt in a straight line and reverse you steps in the reinstall of the top cover or bottom plate. 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.

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.
