OM615 injection pump timing - PeachParts Mercedes-Benz Forum

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.

I learned to time a 616 when I took the head off my daughter 240, pretty hard to do that job and keep everything in time. You need to turn the engine over by hand and if the timing between cam and crank is off you cant hurt anything, she just wont turn. IP timing off, wont hurt anything. I dont know about using the "pin', on your 615 but someone will, good luck. I use the "bubble method" for timing, most will poo-baa that tho

, it works for me when i couldn't get the "drip method" too.

This is an excellent suggestion to keep from damaging things.
