Unknown camshaft
 

Hello all together,


during one of my researching trips in Latvia, I found two camshafts at a old farm. The farmer told me, that they were recovered from a plane crash in WW2. Can anyone identify the camshaft in the picture (the second one has the same measures)?


Lenght is around 107,5cm.


Thank you very much.


Kind regards
Sebastian

Loks like DB601/605...but I would have to pull out some manuals to confirm...

Re: Unknown camshaft
 

Lobes are to close to each other and lobe separation is incorrect for a DB.

Perhaps a non-aviation Straight 6?

Hello

The 7 holes at the end piece and the general layout are pointing toward an Allison V 1710 (Bell P-39, largely used by the VVS). But I have to make further verifications.

Hello,


perfect, that must be the correct shaft. As there are two of them, they must belong to a 12 cylinder-engine. The Allison looks exactly the same. I will try to find some measures to make it sure.


Thank you all together. Especially to Jean, impressive knowledge!



Best regards
Sebastian

Note the bearing surfaces on each side of the lobes.

Hello, found some more parts from the same crash landing site. Can anyone tell, if they are also from a P-39?


Thanks and regards

Hello
The part with the 12-723-019 number comes from the elevator assembly of the P-39. Always easier with the label !

Alcoa still produces aluminum today, headquartered in my hometown of Pittsburgh. Ball bearing is a Fafnir and is also still in production under the Timken company name.
