turning a giant crankshaft

GIF of a giant crankshaft turning, possibly for a shipping vessel diesel engine. Or, maybe someone on our forum is building a hot rod.

Seems like the throw on the crank in post #1 is very short for a crank that large. Especially when compared to the throw on the one in post #3.

It might just be the lighting in the shop at different angles. How much throw do you think #1 has Hemmjo?

If I had to guess I would say the crank in post one has about 5' or 150cm. The crank pin is clearly offset outside the main bearing journals by a significant amount.



In image 3, the crank pin off set is clearly inside the main bearing journals. I wonder if this one for something other than an engine, perhaps a pump of compressor of some sort. The short throw would surely limit the amount of torque one would expect from an engine that large.
