Sounds like a noob question.. but I actually don't remember how you get it off.. I mean I removed the bolts on the backside of the fan to free it from the.. gear?* not sure what it's called..
also, I have all the belts removed and is it just me or is it extremely awkward to get at the little tiny bolts behind the fan, let alone loosen them..?

also, can't find my Haynes, haha.

 

Yeah PITA I use a 10mm wrench and a screw driver to hold it steady. After the nuts are off it is till a bitch to get it off sometimes.

 

never had a problem getting it loose

 

Wd40?

 

and if you took those 4 nuts off already use a small flat head and keep turning it around slowly prying at it untill it comes off

 

sometimes the studs come off with the nuts
and I used a 10 mm and had a friend hold the fan

goodluck
