Hello all MB lovers

I gave the injection pump on my 190D 2.5 for copmlete teardown and replacement with new componets and soon i have to put it back onto the engine. My question is what is the procedure to properly time it with the crankshaft and camshaft (they both have marks but the pump shaft and pulley doesnt). Also, i heard that the pump should be tilted accordingly (measured in degrees) to adsjust the injection timing (fast or slow). I would like to know what is the number of degrees for that particular model.

If anyone knows what im talking about please help me!!

once again the car is 1986
