It's simple but not quick just a few screws to undo - you will have to take the top then the back off - this means removing the circlip that holds the shaft in centre back bearing - unplug the wires, note their positions, lay dryer on it,s front on an old cushion. lift the back off from the top first, lay it down it will the un-clip - now the fun begins - lay the new belt in position and stick it with 3 or 4 bits of sticky tape you will see where it goes by the marks on the drum - now the hardest bit pull on the motor against the coil spring, pull it right across as far as it will go - it might be tight - hook the groved belt over the motor shat and around the jockey wheel - it's tricky, if you have it correct the belt should tighten when you release the motor if not you've got it the wrong way round the jockey wheel - now just put it all back together again - good luck.
