Crank pulley bolt on what year? what engine? we need to know these things so we can help you lol!

Service manual has two specs for installing the pulley - one with the new and one with the old bolt. With the new, the pulley is installed with the bolt seat face of the pulley .095"-.175" sticking out from the end of the crank. Then the bolt is torqued to 37 ft. lbs. and then rotated another 140 degrees. With the old bolt the pulley is similarly installed and the old bolt is torqued to 240 ft. lbs.

Crank Pulley Bolts 63 lb. ft.
Crank Hub Bolt 74 lb. ft.
