How do you remove the bottom plate, in order to install a new belt?

Eureka says size U BELT... NO!! I have tried this numerous times. I finally took off a belt from an old vac. and it works !!! dirt devil size 5 belt is the way to go!!

Remove the base plate. It is held with screws accessible from under the unit.

Inside you will see the beater bar and the belt.
Remove the beater bar. This is self explanatory once you see inside the power head.
Remove the old belt.

Find a replacement from your local dealer or online.

Replacement is the reverse of removal.

This is a simple job you only need a screwdriver.

Good luck, please rate this answer. Thanks.

Good luck

Turn the vac over so the brush is facing up.. There is a cover plate that surrounds the brush.. Take the screws out and remove the cover plate.. Pull up on the side of the brush that the belt is on.. Replace the belt.. The belt goes around the metal shaft and the brush.. Push the brush back in place.. It might be a bit tough going in because the belt causes some tension.. Put the cover plate and screws back in..

Good luck ! Please don’t forget to rate well ;o)

the belt is on the bottom right (looking at it from the front). the Eureka website does have the manual for download, http://www.eureka.com/service/manuals/80244.pdf

With the vacuum flattened (straightened) out, turn it over and remove the back roller cover, (2 screws) once off, the roller should just pop out on the opposite side (opposite from the belt). Don't forget to turn the roller to center the belt once you have it on.

Hi Jim You should find the cross head screws on top of the hood - look below the duster and there should be a screw there, also another screw on the other side and two either side of the main floor head. 

There are two screws on the top side just behind the Brush housing. Remove these two screws, one on each side, and the top plate can be removed. Then you can follow the directions above.
Hope that helps.
