I hope you don't mind asking you for advice but you seem to be my last hope as i cannot find anything on this make of tumble dryer. What it is the machine was making an awful noise so we bought some new pulley wheels for it. My husband has taken it to bits but now he cannot remember how to put the belt over the wheels?? The wheels have a spring inbetween them. All the other machines seem to have 1 wheel and not 2, and with the fact i cannot find any help or diagrams as to how it goes on we have a dryer that is so far scrap. Like i said i hope you don't mind me asking as this is the only thing stopping us from putting it back together and using it. He didn't notice how the belt went over the pulley wheels before he took them off ! 
Thank you very much.
