well just had my falcon alternator come for my suzuki and im trying to get the nut undone so i can get a v belt pully onto the alternator as it has a flat belt one on there. i have tryed undoing it both ways first the way the thread looks like it is going and when that didnt work i tryed the other way. i has a bit of movement with a long bar but the nut didnt turn something else did as i marked a line on both the nut and the thread. hope someone can help. there is a pic below to show what im talking about.
i start with a 3/4 inch rattle gun then go to plasma/gas axe good luck getting it off they can be a pain if you arn't keeping pulley put it in a vice do it up tight then attack with socket and powerbar worst poss you smash brake the pulley off hope it helps
