Stihl BR 550

[NSG]

Hi got a Stihl BR550 4stroke blower I've been trying to get fan nut off and have been unsuccessful. Wich way does the nut come off is it regular tread or opposit. Ive been using a heavy duty impact gun no results I even had it in a vise holding on flywheel, but that was a bad idea it broke the aluminum key way. Any ideas I need to get it apart to get to the engine

Hope you got the fan off. A service manual for future reference would be useful. Check your inbox.
