NO do not remove the stuff from the top. Remove any plugs , wires etc. Remove the loading mechanism.. should be a couple of screws. Now you should see 3 or 4 screws holding the whole mechanism to the plastic frame. These should be pretty large screws. Now lift the whole mechanism out and flip it over carefully on a towel or something soft. Now you can get to the mode switch and mode belt.
The SM that I downloaded is missing parts of the exploded views. I'm guessing yours is the same.
Try this manual. I believe the mechanism is the same as yours....
