I seem to come up with some strange ones from time to time…

I am putting the new head on my engine, and I need to get the camshaft timing figured out. While I have this engine torn apart, it seems like a good idea to get the cam timing spot-on instead of relying on the relatively crude method of lining up the timing marks on the cam tower & thrust washer.

My car has a camshaft that is not listed in either the service CD or in the Haynes manual.

It is stamped with “code #11”. There are specifications listed for cam numbers 00, 05, & 08, but nothing for 11.

In addition to the timing specifications, does anyone know what application this cam is specifically for? The car is a 1984 300D. The engine has not been replaced; it is a California version – perhaps that is the reason for the odd cam. Maybe this is the camshaft for the 1985 (higher output) engines? I don’t know…

I hope that someone enlighten me with some information on this… Thanks in advance!

MB camshaft are numbered for the valve timing by their part number. ie; 617-051-05-01 would be the EARLY turbo camshaft & the "05" is for the cam timing. THE "11" is from 617-051-11-01 and is the replacement part number for the "05". SO the cam timing info is the same as the "05".

M.B. Doc:

Thank you very much for the info… I GREATLY appreciate it!

Just out of curiosity, two questions arise:

1. Does this mean that the camshaft had been replaced on this engine at some point in time? (Meaning that the 05 cam was used at the factory, and the 11 cam was *strictly* the replacement part?)
2. Why would MBZ use a different part number if the timing parameters have not changed? (Assuming that the material is the same).

Thanks again!

The "11" shows up in my TDM all the way back to 1983!! Should have been the OE camshaft!!
