Interesting thread.... I'm going to make sure I don't miss a gear!

When these flywheels come loose, do they shear all the bolts or do the bolts just loosen? Because if they are shearing, I can't see loctite helping. Also if you use loctite you can't use oil on the threads, and if the torque settings are given with oil as the lube, if you do they up with loctite you won't get the same tension in the bolt for a given torque setting. Overtightening is playing fire because you could reach the yield strength of the bolt- then you're in the ####e for sure.

Having the two fitted bolts like R-fast said sounds like a good idea, but I think if the bolts are shearing, extra dowels would be even better as they are sharing the shear load out a bit more, reducing the load on each bolt.
