I have a 1993 300 D. I found an external coolant leak in my head gasket so pulled the head and it is currently at the machine shop. To cut a long, painful and slightly embarrassing story short, (I couldn't get the timing chain guide of - I ended up cutting it apart), I moving the timing chain with a number of revolutions of the crank shaft. I am pretty sure that the timing chain, which I held with my hand as I turned the crank shaft slipped on the injector pump sprocket. So how do I make sure I have everything lined up properly? I know that my chain was 1 degree of Top dead center before I pulled the head. How do I make sure that the injection pump in synced correctly? Help greatly appreciated.

 

get a manual, and good luck, sometimes you have to take the engine apart to get the chain back on course.
