I'm looking at your linked thread, thats a good option to remove the steel screw to get the space opened alittle. I was looking at the nylon screw on mine and thought this looks too soft to turn, but it looks like it has to be separated from the flywheel to get the belt past it. If you look at the motor pully on my picture you can just see a piece of the old belt stuck on it. I tried removing the belt and cleaning the pully as attached, what a bear to clean. The motor pully still has sticky gunk I cant get off 100% I used rubbing alcohol, and then mineral spirits both with q tips. then i used dental floss and kite string soaked in mineral spirits and spun the pully with it, trying to pick up what I could.
Is there an owners manual out there on the web. The service manual doesn't tell how to use the player. Lots of controls and adjustments for recording and I guess playback on this deck.
Rich K1 thanks for reponding.
