Remove Tension Pulley

How does one remove the TENSION PULLEY. This is the small pulley that sits between the power steering pump and AC compressor? This is on a 98 Eclipse 2.0 DOHC.

Why are u removing it? There is a bolt on it and u unscrew it and pull it off but u need it to keep the belt tight

Am removing pulley because the bearing is shot. Easy enough to get the hex nut off the pulley bolt. Problem is that there is not enough room between the pulley and the sheet metal of the fenderwell to withdraw the bolt and remove it.
