Ah, bum clouds!
I've only removed one on a 360...
Are they basically bolted through a pair of 'nobbles' in the bellhousing, but there's not enough depth to get a tool on the nut? I have a picture in my mind of a very narrow spanner working...
Might this be B172 only? I can't remember what a B14 one looks like, but my mental picture is of a 360-style fixing. Confusion...
cheers
James
