    I've just joined the forum and I'm hoping that someone can advise me on how to remove the retaining nut on the front sprocket. Is it normal right hand thread or is it left handed and I'd there a way of locking the output shaft without damaging it when trying to undo the nut. All advise greatly welcome, cheers.
