Reply To: Crankshaft nut

Mark,
I agree with Bernie, you have to destroy the nut. It might be welded on one point to the crankshaft, what I found with all my 15-6D engines. Then we prepared new nuts with standard measures for a big spanner and the security fixed as shown in picture. Don’t mind, in the photo it’s a 15-6G engine, but our procedure was identic to D-engines. This G-engine ist entirely rebuilt in CH, its brother beside. Mark Harding put the one in the picture into my 15-6G Berline 1939.
