I'm putting my engine back together and the crank spins freely until I put the crank pulley on. When I take the pulley off and just put on the crank bolt it spins fine. the torque wrench I am using only goes up to 150 but when Im tightening the bolt with the crank pulley on it, the crankshaft doesnt even turn, and I know its over 150 ft lbs...need help asap as im working on it right now. thx.
