Mercedes W154 motor (M154/M163)

[totoslot]

Hi,

I'm new to this board and this is my first posting.

As intro a few words to my person: I'm nearly 45 years old, working for the R&D dep. of Bilstein shock absorbers as dev. engineer near Wuppertal/Germany. My main hobby is 1/24 oldtimer slotcar racing, collecting and building.

I need some (pretty special , I guess) information of the 1939 Mercedes M154/M163 motor. I've easily found the corner stones like bore, stroke, etc of the 60°-V12 as well as a cross-section of the 1st (I think) cylinder bank. The needed data has to do with the crankshaft angles (there are a lot of possibilities ). Of best help would be a pic (or drawing of course ) of the crankshaft and/or the camshaft and/or the ignition sequence and angles.

Every hint is welcomed. Thanks in advance !!

I have been told by a friend that the ignition sequence of the M154 resp. M163 was 1-12-5-8-3-10-6-7-2-11-4-9. This information was taken from the Heel book "Die Akte Silberpfeile" (the internanional title could be "the file silver arrow"), ISBN 3-89365-840-8.

If this is correct the crank pins should be located on a 3x120°(x2) crankshaft, with the crank pins #3 and #4 [of cylinder 5 and 6 resp. 7 and 8 (in the middle of the motor)] being in the same plane with an ignition offset of 360°. It seems to be a kind of flat-plane V12.

It would be great if someone can confirm these data and add more information.:confused:
