Alright, I confess to be the guy who will rebuild injectors for Dan. I've done about 8 sets so far with good results. Although I don't usually keep cars long enough to know the long term reliability, I did a set for my uncle's 300TD about 40k miles ago and its now one of the quietest 617s I've heard. (It takes a few thousand miles to break these it)
Anyway, its a pretty simple process and the quality of the rebuilt is completely determined by how much time you're willing to invest. For example, you could do 5-6 injectors in an hour by just swapping out the nozzles and not adjusting the opening pressures. Adjusting the pressures is what takes the most time. You have to put them together, test, then take them apart and change the shim if an adjustment is needed. You end up taking apart each injector 2-3 times. You also have to carefully polish all sealing surfaces on a very flat surface to ensure they don't leak. I just did a set for my 350SDL yesterday, and spent quite a bit of time shaving down shims with 800 grit sandpaper to get the size I was after. I have built up a good collection of shims, so I seem to be able to find the ones I'm after with only a little modification. It probably took me 3-4 hours, including ultrasonic cleaning of all the parts. I use nozzles from Mercedes Source, or where ever I can get Monarks from. As for the tester itself, I've been using the modified bottle jack from MS for about 5 years, but I just treated myself to a real Bosch tester, the same MB recommends for these cars. It comes (from India!) tomorrow. I suppose I could rebuild injectors for people on the list here, but keep in mind my turn around time is slow with a full time job, two kids, and a garage full of projects. I usually charge people $75/hour to do stuff, but I don't know if thats reasonable in this case of not. As for the 350SDL, I just finished quite a bit of work. I took it for a ride yesterday and it goes like a bat out of hell. Adjusting the injection timing probably helped too. The throttle response is really outstanding, so much so I'd guess its going to be pretty impossible to drive in the snow. Jaime On Wed, May 4, 2016 at 5:23 PM, Kaleb C.
