I wonder what the millions of Small Block Chev owners would think of the above crank damper pics given that most of the 'plain jane' SBC dont use a bolt or washer to retain the damper/timing sprocket on the crank snout, relying totally on the light press fit at assembly. Ford Australia did the same with most of the inline 70's 6cyl stuff as well, this in spite of the crank snout already being drilled/tapped for a retainer bolt.

I asked the Aussie V8 Supercar guys which thread direction they use on the centerlock nut/hub assy's- apparently they originally made both LHT/RHT nuts/hubs available, but most teams now use RHT only- the KISS principle at work. With all thread direction the same you dont need rattleguns/crew specific to each side of the car for pit stops.

As mentioned above, there isnt a problem until the nut comes loose- working out what is the cause of the nut coming loose appears to be the problem.

Incidently,I remember trying to degree a cam on a Boss 302 years ago while the entire valve train was in place, had removed the single bolt holding the CAMSHAFT sprocket while making the necessary adjustments and while turning the crank sheared the dowel in the cam nose simply for the lack of that bolt .
