200 sx crackshaft pully bold struck
 

1998 200 sx se 1.6L

I am having problems getting the crackshaft pully bolt off I have an air impact wrench and it move a little but wouldn't unscrew. My wrench is rate at about 300 lbs/in. I am a little concerned that it might be a reverse direction screw. So does anyone know if it unscrews clockwise or counter clockwise. I have worked it a little both directions but mostly counter clockwise. Does anyone have any other tips for removing it?

Thanks Dewayne

well i just put a unorthodox underdrive pulley on my 1.6L sentra and what you have to do is have someone put your manual trans in 5th gear and hold the the brakes and your impact should be able to undo the bolt but make sure you have a puller cause mine did not want to come off with ease so i had to use a puller and also your going to have to repeat that but torque the bolt at 145 pounds of torque. check this page out it will give you installation procedure for your crank pulley. http://nissanperformancemag.com/january02/ur.shtml
