You have to take the top off... 2 screws, under the lint filter. Then thin bladed putty knife, about 1-2 in from the sides, push in, lift, tilts back.
2 screws, hold on the front, tilts down, drum kinda falls out. If you're mechanically inclined, you'll figure it out from there.
If not, let us know we can talk you thru some more. Look on web, exploded diagrams, use your model number in the search on google.
Belt wraps around the drum, and a spring-loaded tensioner to keep it tight.
Make sure the unit is unplugged before you start,
