All I know about this in general is the timing cover will need to be pulled off and you will see marks on the crank, cam, and injection pump all have to be lined up before disassembly so reassembly is easy. other methods might be but not known to me.
Yep!!Im sure you figured out that the common rail pump does not need to be timed. The pump only pressurizes the fuel rail and the injectors are electronically fired and timed by the ECU.
Be careful! Don't know about the Doosan, but while most common rail pumps will work fine with no timing, I do know that the Kubota/Cat ones have a timing sensor wheel on the pump drive gear...Yep!!
Common rail pumps do have to be timed! The pump is like a mini, opposing 2 cylinder motor. There are 4 injectors, they time the pump so when it's creating the most pressure on one of the strokes of the pump it coincides with when one of the injectors is firing. That way the injector is getting the most pressure the pump can produce right at the same time a it injects. If it's not timed the injectors will be getting pressure created when the pump is in the middle of a stroke and not top dead center at its highest pressure produced. Make sense?

Yes the kubota/ have a timing wheel and a timing procedure but it's super easy the doosans do not need to be timed
