Hi Des
Any idea about what caused this failure?

This link has some photos of the catastrophic failure of the engine in our Sexton and some suggestions as to what happened.

Here's a cross section of the C1 crankshaft that may shed some light on where stuff is located on the photos above.
Any machinist that was asked to convert a -46 crankshaft to a C1 or C4 would need a sample of each to see if it was feasible, I figure. Not to mention when the surface hardening was done. Malcolm Sexton crankshaft.JPG

Malcolm Towrie Having worked on engines like this...I would say this was a Prop Strike.... Dump the Clutch ...sort of incident. If it was engine oil trapped in the lower cylinders...we would have seen seen bent rods...And there are none. Unusual to have the balance end of the crank be broken off like that.

I am inclined to agree- must have been quite a shock!

Very interesting but kinda ugly, John, unless you're into the steam punk look.
No shrouding on the cylinders and no sign of the huge fan on the tank engines so how's he going to cool it, especially the lower 3 cylinders? And try ordering at Timmy's. Malcolm
