Hi Bryan, that's the very thing I had planned, the stud maybe against the back of the machine, then is that not always the case ..
.. wonder for the location and cracked case had been down to something could have dropped on it at some point, damp since got in an caused the failure ... And yes cut then change out color/# for color/# on replacement.
Paul, well done there, yep, that's the closest Maplins and likely to have one, just the case of fixing and cable tabs/end .. or as pictured looks like spade lugs, maybe not to cut current lead short.
Maplins has most things, wonder if they'd have a drive belt.. all happens at once.
Cheers David
