you need to undo all the little screws on the back
then the bolt on the fan the fan will then pull off this may be difficult as they stick on and may break the fans are about £4 on ebay
then the 2 screws that hold the heat element
there is then 3 screws that hold the drum bearing in place note the way round as it only goes back one way
the back should come off then the belt is located on the drive shaft in the grooves and round the drum then put back together in reverse order
hope this helps
