Rebuilt the engine and it's been running fine in the garage, then I noticed how slack the fan belt had become.  When I tried to tighten it up it just threaded the stud.  Other than buy a new dynamo what options do I have ?

I presume it is an M12 in size, what if I re-threaded it to M10? is that possible or is there any other way that anyone can think of?

Failing all of that, does anyone have a Dynamo they want to sell ?

I am sure I have my old Dynamo somewhere.  Let me look on Saturday.  If I do you can have it for a £5 donation to RMCH 

Thanks Tony, Yes Please.
