190db diesel timing chain installation

[Angus Wylie]

Hi
I am putting together a rebuilt om621 engine-- The timing chain needs to be installed and the fuel injection pump also

First I set the crank at 45 deg BTDC--first cylinder is now in compression

Second I align the marks on the injection pump at the coupling to the engine

Third I set the camshaft sprocket spacer mark to the mark on the first bearing housing to set the cam.

Now I can install the timing chain

Is this correct?

Thanks- all comments appreciated!!
