Factory book shows a nut,

Remove nut, then use a special puller to remove the clutch plate and
hub. Then use another puller to remove bearing and rotor. Then you press
out the old bearing. Press in the new one and stake it in place. Then
use an installer and put the bearing and hub back in. Reinstall hub and
nut. Recharge and enjoy.

Personally I would replace the compressor with a good used one. If not
get the idler pulley and bracket assembly off a vehicle without A/C.

Oh and FYI There are a LOT of vehicles out there that operate the same way.
