I managed to fit this belt, albeit a little later than we'd have liked. It might have been my oversight to have gotten it delivered sooner.

When trying to fit it, I was almost convinced it was the wrong size, as it's a very tight around the drum and there is very little "slack" to loop the belt over the motor spindle.
How wrong I was!

A little perseverance with a large screwdriver and some ingenuity with the pulley guides and its own tensioner spring, finally I had the belt on and it was all up and working once again. :-)
