1. remove top plastic panel (retaining screws are at back)
2. locate metal brace (12 incles long and 1/2 inch wide) on top of the cabinet (in mine it is on right edge)
3. unscrew retaining small bolts (there is one a few inches below on the inside of the cabinet too).
4. Repeat for left side.
5. push the back and front halves of the cabinet away from each other
6. slide the new belt around the front of the drum
7. reassemble
8. if you need to tension the belt wrap 10-20 turns of insulation tape around the idler pulley
