The drum is next. Make a diagram of how the belt is arranged on the belt tensioner and motor pulley. Reach behind the motor at the lower right and take the tension off the belt to remove the belt from the motor pulley.

At this point the belt can be replaced by slipping a new one over the drum and attaching it to the tensioner and belt pulley.

Be very careful that the belt is not twisted and it is close to the wear track on the drum where it was running.

Turn the drum slowly by hand to ensure everything runs smoothly.

If replacing a belt, you are done. Reassemble.
