Thanks guys, I don't think it will be possible – or at least, not easily and within my capabilities. It has the triple pulley, and as far as I can tell without some further dismantling, there's nowhere for the front side of the belt to go. The rear side of the belt might just make it though, but that's kind of irrelevant.
Thanks for the input and information. I'll just live with it the way it is.
Regards,
Rob
