Harmonic balancer
 

I have a 1979 300D MB the Harmonic balencer has come loose and spins on the crankshaft How do i get it off.

Is the outer ring spinning?

I have no idea on what a OM617 harmonic balancer looks like- post a picture. Should be easy- most car you use a puller after removing the crank bolt.

Or is it spinning b/c someone has removed it and knocked the key out of the crank?

Hate to be pessimistic.
 

But a free spinning HB on a Mercedes Diesel has been the death of many cars. You will have to pull it off and take a good look at the front or "nose" of the crankshaft. If that is all beat up, you will have to look for a replacement engine. You can find a lot about this problem if you do a search on the diesel side of the forum.
