The belt may look ok, but if it is more then a few months old, then it has stretched to where it won't turn under load, just slips. If it is very tight feeling, then check down where the pulleys are, the V belt has a black roll that maybe jammed and not pushing against the V belt when the handle is in the down position.

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.

Replace belt on hoover vacuum U4655


Turn the machine over and remove the 4 screws which hold the cover on the brush. Remove the cover and brush roller. Remove old belt. Slide new belt over the motor pulley, first. Then slide roller through new belt (if self propelled model, slide roller through the small belt, also) and slide brush roller into slots on housing (note: slots are different, match roller sides to correct slot.)

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.

The belt on my hoover cordless is not spinning when I turn it on


You need to replace the belt. Even though the belt may look fine it can be stretched and therefore it won' t turn the roller brush against the resistance of the carpet. You can get Hoover replacement belts here:

The belt on my hoover will not stay on. It falls


Okay. I would suggest that you have a problem with your roller brush. If the roller becomes clogged with hair/debris, the bearings will sieze, and sometimes even melt the plastic. the roller then has a difficult time turning and will break the belt. If the belt is slipping off, I would suggest that you either have a worn belt, the wrong belt, Or, your "windtunnel" (the half cylindrical insert the roller sets in) is missing. this insert has a "belt guide" that keeps your belt aligned. hope this helps!!!

Brush stops


This really sounds like a belt problem. Even if it looks OK, it may have stretched. New belts are cheap, and you'll need a new one eventually - if the old one turns out to be fine, you can always keep it as a spare. A second possibility is this: Many cleaners have a control which allows you to switch off the brush/beater bar so you can clean wooden floors without damaging them (for instance, mine has a pedal-operated bar which shunts the belt between two adjacent pulleys on the brush roller, one of which is properly keyed on, and the other of which is a loose fit allowing the roller to idle. If you have something like this on your cleaner, check you have the brushes switched on, and that the mechanism is working properly. A.
