Yes - good point. I think that only applies to the 3.5's though (and OM606).

I believe there used to be, but MB did away with it. They revised that front crank seal a dozen times, and interestingly, some engines specify different seals within the same supercession. For example, engine 1 shows seal A replaced by B, which was replaced by C, D, E, and finally F. However engine 2 may show seal "D" as the final replacement, not E or F. Very weird. I've not ordered the different types to compare them though.

If the hub is not badly scored, it appears to still seal ok when left alone, at least when using the new OE seal that I referenced earlier. I've done this on four different OM60x engines with no leaks thus far, without resurfacing the hub. On two of the four, I had the Woodruff key push out of place, causing a great increase in heart rate and blood pressure until it was safely retrieved. Now I'm paranoid about that darn key!
