Greetings from GoVacuum,
Make sure the vacuum is NOT plugged in. In order to replace the roller brush, you'll need to unscrew the 6 screws on the bottom plate of the vacuum cleaner. Oreck uses a Phillips Head screw, so you'll need to get a Phillips head screw driver to replace the brush.
After removing the screws from the bottom plate, simply pull up on the plate by putting your fingers into the open area where the existing brush is located. After the bottom plate has been removed you will have access to the roller brush and belt.
You can now just grab the roller brush and pull straight up on it. It's beneficial to change the belt of the vacuum when you're replacing the roller brush anyways. There is a spare belt on the actual bottom plate of all Oreck XL vacuums.
You'll notice that the new roller brush has two black square plastic caps on both sides of the roller brush. You can look on the outside of this black cap, and you'll see the words OLD and NEW. Rotate the NEW side so it's facing upwards, and the OLD side is the side that's down inside the vacuum cleaner, make sure that both sides have the NEW side facing upwards. You'll need to wrap the belt around the silver pin in the back of the vacuum on one side, and through the roller brush's metal pulley on the other side. The just stretch the belt with the brush inside of it, and place the black plastic parts back into the vacuum cleaner.
Congratulations, you've now just replaced the roller brush in your Oreck!
