Hejsa
Har knipset lidt info fra nettet..
There are no belts that move the tone arm on your turntable there is a small motor that has a worm gear on it that is what moves the tone arm from the tone arm rest to the record and back at the end of a record. It could be a couple of things that are causing your problem. 1) the motor for the tonearm is bad, 2) the worm gear is stripped because of old grease in the gears or old grease is not letting it function correctly. 3) or the micro switch if there is one that turns the motor on when you hit the start button is dirty and needs cleaning or is bad.
Altså ingen rem til arm-step-motor, men tandhjul som trættes med tiden, indgroet fedt, switch fejl mv. - Og regn med det er ret kompliceret at udbedre, hvis de bevægelige dele i armen skal adslilles og dele skiftes. ( 1. postulat )
Lidt mere hvor den er adskilt:
