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

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.

nah no more Hot Rods,,biden will win and pass cash f clunkers 2 and 3, banning modified vehicles ,destroying nonworking black tagged vehicles,and v8's and anything over 200 HP for us ordinary folks..
