I hope they help.
here are the instructions:
remove with a skinny 32 mm or 1-1/4" open end wrench. Wack the end of the wrench with a large mallet -- note that it is a left-hand thread. The nut will now unscrew. If the pulley slips, tighten the alternator belt & push the belt down to take up slack & smack it again. If it still slips, you can sacrifice the belt & clamp a pair of vise-grips on it just ahead of the pulley & replace the belt with a new one. There is also a BMW tool to hold the pulley to keep it from rotating. Store the fan clutch vertically if reusing. I used a cheapie wrench from a discount tool supply & cut it down to 1/4" thick with a flycutter on a mill. One could use a grinder but that takes a while. You might be able to get a skinny wrench at a bicycle shop. Alternatively, you can remove two of the adjacent 6 mm hex screws on the fan pulley to make room for a large crescent wrench.
