Unpluged dryer first. Then took the lint filter out and removed the two philips screws inside the lint filter lid. Then take a paint scraper just under the top of the dryer two inches from the left front corner and pushed in a little to release the snap connector and did the same on the right side. Then lifted top over. Then take a 5/16 socket or nut driver and remove the two screws on on the left inside panel, then the right side. Lean front out a little and remove the two wires one the back side of front panel for the door safty switch. (note make sure to write down which wire was on each side).Then lift up on front panel and remove front. Grab the drum and remove. Then clean all the stuff that will be on the bottom inside of dryer and if your lucky there will be a pocket full of change and other items from your pockets. I used a vac hose to suck around motor and to pick up lint. Then slip belt over drum rib side down on the wear mark on drum, put drum back in place. If you have help have them hold the drum in place or prop up front bottom with what ever you can find. Reach under the drum near the front of the motor and put the the pulley back in the slot where it goes it only goes in one way. Make a small loop and slip the belt under the plastic pully wheel and slip the belt over the motor pulley(note you will have to pull the belt with sum force to pull the tension pulley back enough to reach motor pulley with the belt).Take a deep breath your done with repair. Reassemble dryer in reverse order, plug back in and test. I have done it before it took me about twenty minutes, after cleaning should only take about an hour or less.
