Ok,
So I got everything apart, but I'm the idiot for not realising I have to cut the bottom of the cowling as well around the lower pipe.
I hope you guys don't think this is too funny, but I actually have problems with my dexterity and coordination.
Anyway, finally managed to get it all off, now I need to work out how to test the fan, any clues for testing or do I make the big assumption that it's definitely the brushes.
BTW, if I haven't thanked everyone for their assistance yet, I am very grateful for your help.
