The belt appears too small. But its a 'stretch belt' and will stretch to fit, unbelievable though this may seem. The problem I had was stretching it enough in the right direction, ie towards the motor shaft.
My technique involved using the snapped drive belt. Wrap the new one all the way round the drum, loop the snapped belt through it and pass it through the slits in the bottom of the dryer by the motor. Tie it in a knot and use a suitable lever against the edge of the dryer to stretch it in the direction of the motor shaft. Watch your hands on the sharp edges of the motor casing. A second pair of hands could be handy here, one to stretch the belt, one to guide it on.
