Rick E1, it looks like the Motor Pulley, Elna #440152-20 needs to be replaced on my 722010 model (flat on one side from standing around. It looks like some kind of a set screw which keeps it attached but are you familiar with how to get this item off the little shaft it is on. Also, any idea where I could find a reasonably priced Motor Pulley.

There are actually two belts on your Sebo, one that drives the brush, and the second that attaches to the pulley on one end, and the motor shaft on the other. I'm assuming that the belt you need to replace is probably the brush belt, or the belt that attaches to the brush gear on side, and the pulley on the other.

Here's what you'll need to do:

Step 1. Remove the vacuum bag housing so that you are only working with the power nozzle or the bottom portion of your Sebo, this will make it much easier to work with. Turn the vacuum upside down, and remove only the 5 screws that I have circled in red:




Step 2. After removing the screws on the bottom of the vacuum cleaner, separate the top housing from the lower agitator housing, sometimes it may take putting a flat head screw driver in between the white and grey colored housing and prying them apart.

Step 3. You now have full access to the belts on your machine. It's most likely the belt that wraps around the brush gear rather then the belt that's attached to the motor that's gone bad. I have never replaced the motor belt in 8 years of servicing Sebo vacuums. The easiest way to replace this belt is to loosen the pulley system that the belt wrap around. Unscrew the two screws that hold this pulley in place, and remove the brush drive belt from the pulley, and now you can unwrap it from the brush gear as well now with the extra slack in it. Now, if you've been using your Sebo in your home rather then using it commercially in a business, Sebo actually offers a lifetime belt warranty on their vacuum cleaners. The belt is supposed to last as long as the vacuum, and Sebo will actually cover this repair, both parts and labor as long as the machine is being used in a residential home environment..

Look under the bottom. Locate the Grill section covering the brushes. This will tilt down when opened. Try either side to see which part flips open. When open, pull the brush toward you. It will pop out in your direction. Lift out the brush along with the Belt. The belt sits in a groove and it may be soft by now. Remove it. Get a new Belt at WalMart. Slip the new belt end up and around the motor pulley and the other end around the brush pulley. The belt will tend to be very tight and need your muscles. It wont brake, so use some strength to get a good connection. When the belt is on both the motor pulley and the brush pulley, push the brush back into the chamber and lock in place. Your done.

This unit has 2 belts. The V-belt on the brush usually doesn't cause problems. The larger flat belt requires regular replacement ( belt # 38528-035 ). The belt is first placed around the motor shaft toward the rear of the machine, and then around the large pulley. You must have strong fingers to stretch the belt over the drive pulley. Start the belt at the top of the pulley, and try to "roll " it around the pulley a little at a time, holding the belt firmly around the pulley as you go.

To change the belts, make sure the vacuum is not plugged in. Lay it upside down and remove the screws holding the bottom plate on. Remove the bottom plate, pull the brush roll out noting how the belt goes so you will know how to put it back together. Especially how it goes around the idler pulley. Remove both belts, replace both belts, install the V belt onto the transmission first then around the brush roll and put the brush roll in place. Install the flat belt around the motor shaft and then onto the transmission pulley.

Always make sure your machine is unplugged from the outlet before replacing the belt.
Newer Oreck uprights have an access plate on the right hand side of the base (as you're looking at it from the front). Remove the one screw from the access plate and slide it forward. Snake the new belt around the brush roll pulley and then strrrrrrretch it back to the motor shaft. Replace the access plate.
If your model does not have an access plate; turn the machine upside down, Remove all screws. Lift the bottom plate off. Observe the position of the brush roll ends, One side of each end cap will have several notches cut into it,this is the 'new' side, the other side is smooth, this is the 'old' side. You can reposition the brush roll the the 'old' side if your bristles appear worn down.
With the brush roll still removed; place one end of the belt over the motor shaft first, place the other side of the belt around the brush roll pulley and stretch the brush roll forward until it is back in place.
Spin the brush roll by hand before replacing the cover to ensure the belt is not pinched.
Replace to cover.

Hello,

The roller drive belt may be stripped, worn partway through where it goes around the motor shaft, thrown off the motor shaft, or broken. Take the bottom plate off the carpet sweeper and have a look.

If the belt was damaged when the roller brush got stuck, then you get to replace it. On most of these, the easiest way is to put the new belt around the roller pulley, reinstall the roller, stretch the belt around the end of the motor shaft, then turn the motor by hand while pushing the belt on. If the motor also has a pulley on it, you may have to remove the motor screws to get enough slack on the belt, then pull the motor into place and put the screws back in.

Remove the bottom plate, the V belt goes around the inner pulley and then the brush roll. The flat belt goes around the motor shaft and will stretch to around the bigger pulley by the V belt.

Take off the bottom plate, there are 2 belts, the V belt (38528034)goes on first, it goes around the pulley then around the brush roll. The Flat belt(38528035), put it around the motor shaft first, then stretch it to go over the bigger pulley.

You didn't give your model #, but most Hoover's, if you turn the vac ove, take out the screws to remove the plate covering the brush roll and belt. The number of the belt is on the belt, unless it is worn off, it is also on the metal tag that the model number is on. Put belt around the motor shaft or pulley, then around the brush roll and stretch it to put brush roll in place. If this is a wind tunnel, it has 2 belts, one for brush roll, which is a V belt, and a flat belt for the motor to the pulley.
