Broken belt on a Model #U4655-930 How do you get to the engine pully We removed to brush mechanism

Turn upside down and remove the cover you will see how it works any store will have the replacement belt

Barring any electrical failure or loose plug the most common cause for the vacuum brush to stop turning is belt clogged with debris or string.
Unplug the unit and check the brush for string or debris (Hair) wrapped around the pully on either end. Clear this and check the belt to make sure it has not broken, stripped or simply slipped off. Usually the bottom plate is held on with just a few screws. Easy to remove and check Belt slipped off or stripped replace. Belt slipped off you can sometimes put back on and be vacuuming in no time.
Anything wrapped around the spindle a pair of needle nose pliers comes in real handy here. If you have snagged a rug, sheet or sock etc.. check the manual for a reset button. Some vacuums have this and all it takes is clearing the chute then resetting the switch. Good luck hope this helps!

I just changed mine and I will be blunt. First off, the design is **** on this vacume, secondly the belt was designed to break on the rusty carbon steel pully rod. Ok now that I've vented we will get down to business. On the bottom of the vacume you will find a plastic housing thats covering the brush. It will have 4 screws around the brush plus one above them. The housing itself is shaped like an L. Remove all the screws and expose the bare brush. This was not my case but there should be a belt holding the brush to a small steel pully rod in the top part of the L indention. If not then just locate an indention on the brush where the belt will be placed and look directly beneath that to find the pully rod (probably about 6 inches beneath the indention on the brush). wrap your new belt around the metal pully rod and then take out the brush. Wrap the other end of the belt around the indention on the brush and pull up hard and replace the brush in its vacume housing. This will take some effort as the belt has to be stretched. When finished replace the housing cover with the five screws and boom you're done.

There is only one motor which turns the turbine and brush. Therefore, if the suction from the turbine works check the belt by removing the bottom plate of the vacuum and look for the belt attached to the brush roller or if only a piece of the broken belt is inside the unit. If the belt is attached and intact look for a mechanical switch to turn on and off the brush and make sure it is not on bare floor or off. Look on one of the edges of the brush assembly for the clutch which is attached to the mechanical brush switch with a rod. The clutch will close and open when you move the mechanical switch. If you cannot turn the brush unit by hand you may need to remove some objects such as string or hair from wrapped around the clutch or brush.

Without known the type or model of the vacuum you can only check a few generic design futures.

If the Brushes don't rotate, & you have two brushes; 1). Turn unit on side. ( Make sure unit is up-pluged) 2). Rotate the front brush roller, if the second roller moves at same time, 3). Locate a small ribbed belt that goes from the further back roller, to a small ribbed pully. (Gates belt #177-3m5) ( on side under a clear cover) The belt may not be broken, but may have carpet fuzz / lint covering the belt ribs, causing the belt to slip. If that belt is OK and you find that the small pully doesn't turn the belt/rollers, the problem is with a small internal direct drive motor, that drives the brush rollers. At this point return the unit, as Bissell has a design defect & is using cheap parts.

I had the same problem but I found that I had replaced belt incorrectly. After placing one end of belt around pully, it has to be run behind the "belt disengager" which looks like a 1/2" wide metal tab just past pulley. After placing belt correctly I had no more belt, burning smell or brush problems.

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; [email protected]. 1-866-468-2288.

Wish you had given your model number because they are different. On some, the belt goes over the motor shaft, then over the brush roll. Some you have to remove he top cover to get to the motor shaft. Some go over the motor shaft, then over the bigger pully, but then there is a 2nd belt that goes over the small pulley, then over the brush roll. Hope this helps, if not, then give me the model number.

If that spindle you are talking about is the motor shaft, then the motor is bad. Usually the belt goes from the brush roll to the motor shaft. It may help if we knew brand and model number.
