Re: flywheel bolts

yeah im just bumping this up in case anyone every searches for this, but the bolts are 5/16 X 18... has to be in US size because there inst an exact metric size that would fit.

Re: flywheel bolts

pull one of the other bolts out and go to a hardware store and find a nut that it threads into and youve got youre thread and pitch, if the markings on the heads are 8.9 10.9 12.9 etc they are metric if they are slash marks they are standard

I believe that they are 1/2 or 9/16. but watch out when you tighten them up they do not take much torque to break, 40 ft lbs is the max I would put on them. they will break at 42 or so.
