I got crankshaft with part number 5781325-01 on the part. It was in a box of stuff. Do you know this part?
Please ID this crankshaft

Do you have a picture of it Mike?
Bit of a guess, but I think it’s a 372 crank. Inboard clutch so either that or 390. But it has the longer flat spot on the PTO side where it looks like the bushing would slide up to ride on the seal
That's my thought too. An ID measurement of the small end of the rod would clinch it.
Could it be this??

Whats up with the bronze/copper transfer close up to the lobes?
Could that be from a K series saw- like K750 sort of thing?
They had bushed bits inside the bearings didnt they? Not sure if they had the hole into the internals to oil the clutch bearing like some of those cranks for 3120's- never really had much to do with K saws.
OK everyone thanks for the help. Pictured are three cranks. One is the mystery crank and the other two are 365/372.
Can you guess which one? Middle is the Mystery so I think we can safely say it is the same.
