I have askec this question before about the size of crank shaft bolt but i have one that a 14mm bolt will not fit. I went to my mechanic and he checked every thread chaser he had and it appears to be a 13mm bolt and it has not been changed. I thought it might have be helicoiled but who would be that stupid. Please do not tell me that ALL cranks off of sc is the same.

Unless the very early duracast cranks were different every stock SC crank would use a M14 x 1.5 pitch bolt. This is like a fine thread, so possibly your mechanic did not have the correct pitch tap for the bolt.
