Question about Eureka 5856BVZ Boss Bagless Upright Cyclonic Vacuum

1 Answer

The belt on my used Eureka Boss 5857 upright slips off the end of the motor shaft every time the vacuum is used. When I turn the brush roll slowly by hand, the belt walks toward the end of the shaft. It looks like there was a plastic projection from the base that snapped off, and maybe that plastic piece used to block the belt from falling off. Do I need to try to reconstruct that plastic piece, or is something else wrong?

The brush roller could be worn and in need of replacement. Some Eureka uprights have a wire guide that prevents the belt from slipping off the motor shaft.

SOURCE: looking for Eureka belt 70646A for a Eureka The Boss upright

It should be a standard Eureka U belt. That number you have is not a good number. Most repair shops should have this one. The R belt is a real thin and different material.

Brushroll not spinning
Posted by vistaloopy on Mar 19, 2008
I have a Eureka Bagless Optima 431 Lightweight Upright that is not working. I took it apart to clean the brushroll and have tried to put it back together several times, but the brushroll will not spin anymore. Maybe I'm putting the belt in the wrong spot? Where can I find a diagram or something?

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Eureka 431A Optima Bagless Upright Vacuum. You have only 2 choices, the belt is either side driven belt or the belt is a center driven belt and the brushroll has one side that is for the belt and the side driven brushroll and the motor pulley must be in line in order to work properly, you may want to check the bearing holders, some vacs will mark the ends with words like NEW or USED and both have to be identical in order to fit right. Once you have the brushroll out it should spin if you set it on it’s side and if that happens you are OK, then watch the ends of the brushroll. Align the end with the motor pulley, B4 install the belt place the belt on the pulley side and install the brushroll. Then once the brushroll is in and spins properly, and then you can use a belt puller and stretch the belt onto the motor pulley and then track it in a straight line. If you need further help please feel free to contact your local vac dealer in your area. 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.

SOURCE: no suction with Eureka Boss Pro Lightweight Bagless Upright, 411A

I checked the vacuum hose to see if there was a clog. 1st, disconnect the hose from the unit so you have access to both ends. Now, place a marble or other ball in one of the hose and see if it will make it all the way through. I found a major "hairball" about 8-10 in down from the vacuum end. I took a metal cloths hanger and bent it in half and did a "roto-rooter operation. It took about 30 minutes, but now it runs like new. I hope this works for you.

SOURCE: belt location

If you torn the macine over, at the bottom of the sweeper you will see the belt on on side. You have to take the bottom part apart and remove the brushes to replace the belt. I hope this helps.

I tried the electrical-tape-around-the-wooden-spindle technique. After a minute or so, it's back to functioning normally.

I think it is missing the belt. How do I put one on it. It has no suction power.


Remove the three screws on the top of the vacuum base. You may need to recline the handle to the lowest setting as if you are going to vacuum under a bed. Turn the height selector to the side (either right or left), lift off cover of base. Your belt area should be to the right side. Hook new belt on the motor shaft at the back...it kind of looks like a nail sticking out. Pull the brush roll out, clean off any thread, hair, etc. Place grooved end of brushroll in loop of belt, replace brush roll, stretching belt into place. Rotate by hand a few times to make sure belt stays straight.

Eureka boss power plus


I had this same problem. The brush roll wouldn't spin, smoke came out, and it smelled like burning rubber. I changed the belt thinking that would fix the problem but it didn't, so I took the belt back off and checked the motor shaft in the back and found a whole bunch of hair wrapped around the shaft. Once I cut out the hair with some scissors and replaced the belt, everything worked like normal. I hope this helps.

My Eureka Boss vacuum belt keeps breaking


I have been searching the machine for something which could be rubbing against the belt to cause it to fray and break as often as it does. So far, I haven't found anything. I have heard that the belts, called ribbon belts, are terrible! I find that the belts break faster when I use the hose. I haven't found a way to make a belt last longer.

Slipping belt onto motor shaft pulley


On most vacuums, you:
put the belt on the motor,

slip the beater bar thru the belt,

put the end opposite the belt into the frame,

stretch the belt and put the belt end of the beater bar into the frame.

Hope that helps!

Eureka Uno brush not spinning


There are 2 or 3 screws on the top to take out and the top cover will come off. Belt is #61120A U long life, brush roll if you need it is #62365-2. If the brushs look ok and the ends turn freely, then it is probably ok. The belt goes around the brush roll then up to the motor shaft.

Eureka 5197 self propelled bagless upright


Did you check the brush roll when you changed the belt? The smell of rubber would inducate a belt slipping. So if the brush roll (part #61308-2)isn't turning, the belt would get hot and would be slipping. If the motor sounds real loud, then you could have a bad motor(part #60775-4).

The top comes off to get to the belt and brush roll. Did you check the brush roll to make sure that the ends turn freely, or is one not turning, the belt is a lon life "U" part #61120A. The brush roll is what drives the vacuum, but if brush roll or belt is bad, then it won't drive it.
