> just stuck on with a bit of dirt/corrosion - once it's free it'll slide right off.
same thing happended to mine, I would hit it with a hammer and it would rock from side to side but keep on jamming up becasue f the rust. So I pulled at it striaght, came flying off with me too off the chair!
so a little note when you put it back on again, smear the back face with copper grease, it won't happend again.
If it's anything like my old gsi, pray. I had a pulley puller on it, a very big hammer, and a 3 foot bar. Bugger wouldn't shift. Had to take it to a garage in the end, and even they had trouble getting it off!!
