A bit of history first.
Purchased in Oct 09, belt was off upon delivery.
Fixed onsite but belt off again within 3 months.
Fixed onsite but belt off again within another 6 months.
Fixed onsite, belt badly worn replaced along with pulley (teeth chewed).
The drum is now making a very slight scraping noise when turned. If I pull on the pulley and turn the drum, the noise disappears. I suspect the pulley teeth are starting to go again. Does this sound plausible? I think its never been right from day one.
Also, the belt has to go on the outer threads or it comes straight off. Its been like this from new.
If it is the pulley, do you just remove the centre retaining nut and swap over?
Thanks
