606 timing

I need to check and advance the IP timing a little on my 606 turbo. After installed new Bosio nozzles I get a little bit of a ping under acceleration. The manual lists the RIV method with the fancy test box thing. I have the AB light tool. I installed by AB light and rotated engine around to the point where the b light comes on and now both lights, but there appears to be no pointer and no timing marks at all on the damper. What am I missing? Did they for some unknown reason get rid of this seemingly necessary feature on the 606? How do I know where TDC is at the crank?

Yes, seems like you are missing the pointer. I think some of them were bolted on and could be removed and missing. There is a YouTube video out there where he is showing timing on a om606 and the pointer is missing. He does something to get it in the right spot. Can’t remember

Yea but I do not even see any marks on the damper. I see what I assume is the pin that indicates TCD.

If you’re not seeing marks on the damper did you try going another 180 degrees around? The pump goes around twice for every one time around on the crank.

Ok I watched a Dieselmeken video and I see it should have timing marks but the engine he was working on did not have the pointer installed either. I did see where to look though to line it up. I will get back out there tomorrow and clean off the damper to see if I can see the marks.

After watching the dieselmekken video I can clearly see the timing marks in his video. I am back out looking at mine today and I sure as hell do not see any marks anywhere on the thing. It does not seem to have any gunk at all on it but seems to be painted black originally. I have even gone so far as to start scraping off the paint but I still do not see marks. This seems impossible. For grins I came in to look up the part in the EPC thinking maybe for some reason there was a version of this part that did not have marks. This one has me stumped. If I can't find marks I may just turn it till the first light lights up then adjust the pump to light up the 2nd light and see if it helps the pinging.

So there are no marks on my balancer at all, very strange. What I ended up doing is rotate the engine around until the 1st light lit up, I then advanced the pump until the 2nd light came on then where the 1st light went out. I then back it out to where both lights were on. I took it for a quick drive and the ping on acceleration seems to be gone. What is more concerning is the lack of marks. I could make more involved work in the future more difficult to do.

If my memory serves me correct, there is a mark on the timing cam gear visible through the oil filler cap. Once that mark is visible you can advance the motor by hand until you see the "wing" for the IP timing lock on the pump

The pointer on the 606 engine is bolted and is taken out when replacing the water pump. The crank damper should have the 0T and degree marks like normal. - use a sandpaper to clean the damper and rub some some fine chalk to "see" the marks.
