This is a full teardown and the fix that brings one back to life in an afternoon. :STATS | :GALLERY :CHECKLIST Disassembly [x] Pop the battery door and remove the two visible screws [x] Lift the cassette door and unclip the front shell [x] Note the belt routing before removing anything [x] Lift the old belt off the flywheel and capstan [ ] Clean the heads and pinch roller with isopropyl [ ] Fit the new belt and reverse the steps :NOTE Do not pry the circuit board. The flex cable to the tape head tears easily and is almost impossible to source. Work from the shell side only. | :NOTE Measure the old belt flat across before ordering. A belt 2 mm too long will slip and run the tape slow. :CONTACT Sourcing parts Square drive belts and pinch rollers come from specialist audio repair sites and from marketplace sellers who list belts by flat diameter. :LINK https://www.google.com/search?q=Sony+Walkman+WM+belt+replacement+guide Full belt replacement walkthrough
