I'm slowly prepping an OM616.916 to go into my 1960 W121. With the engine on a stand, upside down with the oil pan off, I haven't been able to get the oil seal spacer ring on the crank to move even a little. I know there's a special tool for that purpose, but it's expensive. I looked in the tool rental thread and didnt see it in the list. Anybody have one? Even better, anyone in the Denver area have one?

I suppose I could try to remove it destructively, but to do that without damaging the crank seems like it could be a long, tedious process.
