Detroit Two Stroke

A corny but very informative video on how a two stroke detroit diesel works: http://www.youtube.com/watch?v=k3gMTqaNwlE

Picture A: The crank and cam lined up at zero. Interesting that the cam gear needed to be warmed up to 300 degrees celcius to expand just enough to fit into the teeth of the crank I had never thought to do that. But it shows how close the clearances is with the internals of theses bigger diesel engines.
Pictures B-D: The rest of the internals the beariongs on the crank tightened to spec. and cam seated.
