OM606 Take injectors from IP (non turbo) to install on IP (turbo)
 

I recently bought a used IP from a turboed car and installed it on my non-turboed car: 1997 E300D. I knew it might smoke a little from the extra diesel (posted a topic and received that answer), after installing, it smokes A LOT. I drove it down the street and back and it filled the neighborhood with smoke. So...I obviously can't drive it like that (live in the city).

My question, I want to remove the injectors from my old broken pump and put them on this new (to me) used pump. Any input? I want to do this as soon as possible so hopefully this will work. Thanks in advance!:)

Also, it idles like it's going to quit (and sounds like a truck) and smokes a lot, like I said:) Hopefully I can fix this...:) I will post a new topic with all the things I've done regarding this Injection Pump for anyone else that needs it.

Does these pumps have the ALDA? If so what do you have it connected to on a non-turbo engine?

Nope, this pump is electronically controlled (OM606 not OM603)...so no ADLA that I'm aware of. Thanks for the thought!:)

No! You can't remove the pump elements without having to recalibrate the pump.

If you take both pumps to an injection shop, they can do it but it may run you a few hundred dollars because both pumps will have to be completely disassembled to make the swap.

If you have to go this route, I have a good pump body I can sell you to fix your original problem and you can sell the complete pump you bought to recover your money.

Why did you do the IP swap?

Rolf, he broke the pump body torquing the DV's.

Why can't I just take out the valves from the old pump and put them on the new pump? The valve looks so simple... I would just leave the spring and everything else alone, just unscrew the valves and screw the new ones in. Sounds simple enough:) One of the guys at my work told me that it might ruin the pump because it's not pumping as much fuel it is designed to, but I'm assuming the pump will fail over time and not immediately. Right now I am willing to do this process and buy another pump later on and just get this fixed right now; my girlfriend keeps bugging me to just sell the car but I don't want to:( It's a diesel mercedes:) kiss:) haha

The pump was only 140. I'm more interested in recovering my time in this car lol. It's cheap learning right? lol

It's been a few hours since I last posted. I went ahead and removed all 6 injectors (from turbo Injection Pump) and installed all the injectors from the previous Injection Pump (non turbo) with new o rings and copper crush washers (that I bought a couple months ago when trying to fix the non turbo model Injection Pump).

Most of the plates under the copper crush washers (don't know what to call them) were stiff and I moved them to get them to float around with the diesel. I wonder if maybe somehow they were not closing and were allowing too much fuel which made my mercedes REALLY smoke A LOT.

Anyhow, I work at 5am and get off at 330pm. I will probably go to autozone and get a torque wrench, if I can't get one at work. Wish me luck all you well wishers and positive thinkers;):)

Seem to be talking cross purposes here...

Did you remove the elements from the injection pump itself or the injectors from the cylinder head? The latter is ok, as long as you re-time the pump as the pop pressure affects the start of injection.

So you moved the delivery valves from the NA IP to the Turbo IP? I don't think that's a good idea, and I don't see it helping the problem. If you touch the elements, the pump will need a bench calibration. IPs are built as a unit with internal parts calibrated and lapped to one another. Just as good practice, it's a bad idea to swap things from one pump to another.

I think he just swapped the delivery valves which won't hurt anything but it won't help either. The pump elements are held in place, at least the plunger part, by the roller lifter and a pretty heavy spring that you have to remove the cam shaft to take out.

Why can't this be easy? I took the delivery valves off the old pump and put them on the new one. I thought the holes were smaller and so would restrict the amount of diesel flow. From the posts, I guess I'm wrong and maybe it's the elements? I just thought I could do this with the delivery valve swap. I put them in yesterday and I'm ready to go outside to torque them, perhaps to no avail, I may be looking for another pump. Or perhaps I could do a quick install of a turbo and so I won't have this problem with too much diesel?

So the delivery valves don't control the amount of fuel? I thought it was the size of the hole that mattered. I went ahead and swapped them and it still smokes a lot but it runs a LOT better, I think because I loosened up the stiff seats undert the copper crusher washers.

So...Kartec? You have a body of the injection pump I need? I wouldn't now the first thing to do on moving the parts from mine to yours. Maybe it's easier if I just buy a whole used one.
