Distributor shaft
The shaft which is below the distributor does not turn with the engine. With the distributor in place the rotor does not turn.
Can this shaft be frozen/stuck? Is it broken? Is the oil pump shaft broken? or is there something else wrong? What would be the steps for diagnosing the problem?

It will only cost me $25. It cost me more to tow it home.

I'm lucky.
I was able to pull the two damaged gears from my 280 sl. (my future restoration project) Otherwise I would have had to find another 280 engine or buy new arts, from Mercedes, for $1100. The only thing I needed to purchase was a new gasket for the distributor shaft housing. The process of removal and installation is quite easy. There is more effort involved in removing the radiator than the gears. I am very happy that this job is not difficult. The only down side is I have had to wait for the gasket.

interesting... Now wonder what killed the gears?
Glad it wasn't too painful.

I'd want to drop the oil pan and check it out before driving it again.

The distributor shaft and the oil pump shaft are not together. They are both driven by a horizontal shaft which also drives the injection pump.
The oil pick-ups are attached to the bushings which are located on the top and bottom of the distributor shaft. There was a little bit of sludge in the bottom one. It appears that the bushing over heated and expanded thus binding and stopping the rotation of the shaft. Once it stop the IP shaft continued to rotate and grind away. Both gears were damaged and the bushing is warped. When this happened I was moving at about 10 mph therefore I think the damage was minimal. If this had happened at a higher rpm the damage could have been much more worse. I am going find a machine shop to reproduce a new set of gears and shaft. I will need them for my 280 SL. It is very easy to take the housing of the engine and check the oil pick-ups. Just make sure that you have a new gasket. They only cost $8.
