If too much hair, string, or lint is caught in the brushroll, the brushroll can get stuck. If the brushroll is stuck, it will put too much strain on the belt and may cause the belt to break. Remove the brushroll and clean out any debris from the bearings. After replacing the brushroll, make sure that it turns freely.
Often, a belt breaks because the machine is running over the edge of a rug or other thick items, perhaps even the vacuum cord. This causes “snagging.” When this happens, the belt becomes stuck and usually overheats. Unfortunately, this results in immediate breakage.
This is because at some point the drum was not turning, but the motor pulley was spinning, trying to move the drum. This friction will create heat and cause the belt to snap.
What causes serpentine belts to break? Too much wear due to heat and friction will cause a serpentine belt to break over time. That`s why regular inspections are vital to making sure this doesn`t happen.
Next to the motor, the belt on your vacuum is just about the most important part of your vacuum. Without the belt to spin the brushroll, most vacuums won`t pick up on carpeting at all! If your vacuum uses a rubber belt, check it once a month for cracks, melting, and especially, slippage.
Have you ever broken a belt on your vaccuum and didn`t have a chance to buy a new one? You can make your own out of duct tape for a TEMPORARY fix. This belt is for TEMPORARY USE ONLY, you might damage your vaccuum if you overuse this belt.
Before you spend your time trying to go back over the same areas, hoping you`ll get it all cleaned up the second time around, check out your brush roll and belt. If you`ve cleaned your brush of any sticky stuff and hair, and it all looks fine, you`re likely dealing with a stretched belt.
The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
To reset, remove the Powered Head from the reach wand/handheld and clear any obstruction. Wait 1 minute before refitting the Powered Head, switch the slim vac on and press the brushbar on/off button. Check the user guide for the specific steps for your model.
Use a flathead screwdriver to help lift the belt access door and remove. If belt is broken, gently remove it from the machine. To replace the large belt, place it over the red area of the large pulley that is toward the front of the machine.
If the old belt is still intact, reach beneath the drum and depress the idler pulley to release the tension, then disconnect the belt from the idler pulley and motor drive pulley. To remove the old belt, slide it over the front of the drum. Replace the old belt on the drum.
When the belt snaps, your dryer drum will not be able to rotate around, so it needs to be replaced. Thankfully, it is quite easy to replace.
Factors may include having a bad motor, incompatible pump applications or poor ventilation. Constant overheating may indicate a malfunction.
Your car cannot run with a broken timing belt . By the time the belt snaps, the damage is already done, and you will not be able to drive at all. You will need to have the vehicle towed to an auto repair workshop.
There are two types of belts, one that has snaps, and one that has rivets. A snap belt allows you to open the snaps and remove the belt buckle. A rivet belt is permanent, meaning you cannot release the rivets to remove the belt buckle.
The most common failure mode of belts is a broken belt caused by improper tensioning. There is a tension at which the belt experiences optimum service life. Above this tension belt fatigue translates into a decrease in belt life; below this tension belt slip results in reduced belt life.

Windtunnel belt I have a new Hoover Windtunnel canister. The belt keeps coming off. It happened a couple weeks ago (several times after putting the belt back on) so I assumed I might need a new belt as it might have dried out at the store. I ordered new belts and today I used it for about an hour and the belt came off again, twice. There doesn’t seem to be anything to hold the belt on the stem as it seems to slip off. I have tried it centered, to the left and to the right….can you help. I am v
ANSWER : I’ve successfully used a compatible belt – Royal 104425001 .It’s still new, but for the time being at least – it works.

Hoover WindTunnel Self-Propelled V Belt
ANSWER : I had this same problem with the V belt on my Hoover Vaccuum..
.There are three (3) basic things that will cause the brush roll not to spin..
.1. When handle is upright, brush roll is OFF..2. When switch is set for HARD surface, brush roll is OFF..3. Broken/worn FLAT belt or V Belt, brush roll will not spin.
.
.I noticed that the brush roll was not spinning when my vacuum was set for CARPET. After removing the cover I noticed that the V belt was loose, I thought the belt was worn so I purchased a correct replacement belt and installed it, but the new belt was also loose and when I turned the large flat belt pulley it did not turn the V belt pulley at the same time..
.I double checked the surface setting and I had the vacuum switch set for carpet, but still when I released the handle out of the upright position the brush roll would still not spin..
.My aggravation finally led me to this posting on FixYa’s website..
.The first thing I did was checked the screw to the left of the V belt as suggested by ejmjr5 and this did nothing to solve the problem or create more tension on the V belt, even when the upright handle was not in the upright position..
.After playing around with the surface setting control switch/nob I notice that when I moved the switch out of the HARD surface setting and over to CARPET, I had thought that the switch was set for CARPET as it visually appeared, but I was not pushing the switch over hard enough to click it into the CARPET setting mode..
.VOILA, the brush roll now spins correctly even though the V belt seams to be too loose for the pulley..
.You really have to force the switch into the CARPET setting. Be sure that you hear the switch/nob click into place..
.Now you can effectively clean up after that hangover of a party!.
.Burp!

Is there any way to repair or replace the belt GUIDE on the inside of the belt compartment of a ’97 Hoover Wind Tunnel (not self-propelled)? It became twisted when a belt broke and now the belt rubs against it and sounds really weird, and I’m sure new belts will continue to break.. This guide is a long piece of molded material (part of the compartent wall) to keep the belt from coming off the pulley. It also had a sort of metal clip on it. It was loose and I took it off because of the way the pa
ANSWER : Honestly you should take it to a vac.shop they can fix any vac.

I’m using (or WAS using) a Eureka ”the boss” model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can’t find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?
ANSWER : First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes.

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

Hoover bagless cannister 3765 – belt on power head slips off spindle. bought new belts – same problem. is this a design problem or can it be fixed? I don’t want to take it to a repair shop 100 miles away and have them just put on a new belt. saw idea of smaller belt – what number? couldn’t find suggested royal 104425001 belt.
ANSWER : I would not recommend a smaller belt. You will only wear the motor. This model series power nozzle needs to have a metal clip installed near the belt on the brush roller housing. I know that most of them left the factory without it. Remove the cover to see if one is ther. if not have your dealer send you a clip or a housing with one on it.

Trying to fix new belt to Hoover Turbo Power vacuum cleaner. Don’t see how the belt becomes taut. Fitting it around the roller, there is nowhere to fit the belt to, it just sits loose.
ANSWER : I looked at the user instructions guide online and saw where the ‘other end’ of the belt should be fitted. It was extremely hard to fit but eventually managed it. Thanks for this solution site. I wouldn’t hesitate to use it again.
