Sorry I worded my question wrong.

I have two brand new D52 ordered at the same time, just two weeks ago. The serial numbers on the engine cases are only six numbers apart. So being built so close in production I figured the turbo cuts would be identical.

However they are not. These turbo cuts are just beside the crank pin. So one engine has three turbo cuts and the second engine has two turbo cuts.

HERE IS THE FIRST ENGINE. #11I0199. The Argus crank is on the left side. Disregard the crank on the right hand side. Notice how there are 3cuts.


HERE IS THE SECOND ENGINE. #11I0205. Notice only two cuts. It does look like the machine was about to start the next cut but it never got there.
