I stripped out a thread on the flange of my crankshaft during installation of flywheel at only 70 lbs. I could not find new bolts even at a clutch and brake shop. The old ones I am using have plane shoulder which I imagine is a shear point. Could be the reason for stripping. Less threads engaged in flange or metal fatigue. I am going to insert a heli coil and use grade 8 bolts the proper size. I wii use blue locktite and torque to 90 ft lbs. what ya think ��? I may be posting this in the wrong place or wrong forum but you guys so knowledgeable. Thanks
