OM615 injection pump timing

[kalpol]

I am thinking ahead here for when I put my cylinder head back on - I will assume i let the chain slip on the injection pump drive and need to time the injection pump. Is there any interference problem I might cause if I reassemble everything and the injection pump timing is off?

How do I time the pump? I have one of those pump locking pins for an OM617 that i never used, will that work on a OM615? Suggestions?

I pinned the timing chain together with a zip tie and currently it's lying over the side of the engine looking depressed - hopefully nothing has slipped. I haven't turned the crank, but I sure would like to inspect the bores of 1 and 4 (which are at TDC) before I put the head back on.
