606.910 95 E300D Setting Timing to 14.5 BTDC

[JRImrie]

I got conflicting comments on the post "Correction Injection Pump Timing". The procedure for R&R of the injection pump is incorrect. I reread the cam timing procedure to be positive I don't do it again. How do you find TDC on 606.910 (there are no pin punch marks on the cam sprockets) without removing the cam cover?

Because I obviously don't have enough posts on this forum

Define sprocket. Jeremy's 606.910 has alignment dots on the intermeshing sprockets, not the chain driven sprocket - E300D timing chain stretch



[edit] Oh, [expletive]! This is Jeremy's 606.912. Sorry about that.

Hmm... maybe define TDC - 606 twin cam timing mark question. Might explain why IP timing is off.

Sixto I can see no punch marks on the cam sprockets ( intermeshing). I used the hole that goes through the intermeshing cam sprocket and through the cam tower to find TDC and then 14.5BTC as the procedure says. I do not have the cam cover off I am looking through the the oil cap hole. The procedure says to look for the punch marks through the oil hole. You cannot see the punch marks unless the cam cover is off or when it is coming to TDC but you can easily see the alignment hole. I understand completely and can now proceed the haze and fog have cleared and the conflicting statements make sense. Does not explain why timing is off though.

How far off is IP timing? Center the tang in the RIV port, use the locking tool if you have it, then subtract the crank pulley reading from 14.5 ATDC.

It is also fairly easy to pull an injector and prechamber on #1, and simply look at the piston to confirm punch marks and harmonic balancer findings. Cam lobes will point up on the #1 cylinder.

The timing is off because I messed it up. I had a great great deal of help from the lack of documentation/poor FSM for the 95 E300D. I would guess the Mercedes engineers are getting even with mechanics all over the world. I run into this nearly every time I work on something different on the car. I've been around garages since I was four mechanic'd since I was 9 or 10. Give me a Chilton any day, compared to a FSM for Mercedes, 10 orders of magnitude better.
