This has proven to almost be a miracle power cure for most older turbo diesels."

As for rebuilding, it's a bit of a chore balancing and sealing them yourself. Although apparently that kit's guidebook probably skips on the balancing part. Hmm, no sandpaper...
Probably ALDA. It's not something we weren't already doing. You can hold back your curiosity! Save your $20!

Yes but maybe not SUPER. If the nozzles are not balanced, you'll end up with different amounts of fuel in each cylinder. It may not be serious but it will make it idle a bit rough and you'll have a harder time getting the engine tuned optimally.
I balanced my own and managed to get all of the nozzles set to within 25 psi of each other. Along with a carefull cam adjustment, the idle was really smooth after that.

Exactly. Injector nozzles are changed every 100-150k miles, why would one not balance them, or even think about not balancing, is beyond me...

RED W123 - left Germany as 240D in 1982. Full AMG body kit less rear apron, 2:65LSD, five speed Getrag 717.400, manual steering, read leather interior, manual brake conversion, electric water pump (EWP), and a bunch of other goodies ...
Having rebuilt a bunch of injectors for folks on this forum and others, I can say conclusively that balanced injectors are crucial. I would take a set of weak injectors which are properly balanced and pop tested and cleaned over a brand new set of injectors which are not any day. Second, Bosios are better IMO. I have been putting this out there for a while now. As for German made injectors, not sure about who makes them now based upon the above information. The best quote I got on Chinese nozzles is .79 cets a piece with a 18 month warranty. I need to buy 1,000 of them. I put out a post and got very little feedback on those who would be interested. $20.00 bucks to clean, pop test, balance injectors for an entire set ? If that is the case, then Kerma beats my price by over 50% and I thought I was by far the least expenseive. As for Monarks, Kent has a Monoply. Check out my post where I quoted the head honcho from Monark as he responded to my inquiry. Bosios will cost you slightly over $200 shipped. So, if you change your fuel filters, do a diesel purge, adjust your valves, and install brand new Bosios (heat shields and return line too), that will easily cost you $260.00 and about 2 hours. Maybe that is ultimately what MS is selling? If not, the market clearly reflects what you can procure for about $260.00. The only thing about the Bosios is that they are not always in stock. You might have to wait a while to get them so make sure they physically have them in stock. Actually, they shipped from Washington State although Kermi is supposedly located somewhere else. Hope Kent does not have a monoply on those as well. LOL. I have been jameed twice by KermaTDI so that is why I no longer buy new nozzles for the service I do. Not worth the embarrasment telling folks they are on order.

Bosios cost $43.00 per nozzle right now from Kermi and $47 from DieselGiant.
So, for anohther $2.00 per injector, Kerma is willing to do the entire injector service per injector. So, in other words, he is willing to do an entire set for $10 bucks ? Why would he reduce each nozzle by over 50%? Somethings sounds suspiecious ... say that like Blue. LOL

the guy knows his stuff...20 min on the phone listening to him talk about these injectors and how he rebuilds them...they're highly advanced in the technology and processes. talking about diamond coating the nozzle and pin...nanometers, fuel filters...the man is a wealth of knowledge on this subject.
We discussed leakdown and the bleed hoses .. at length
I'm convinced after speaking with him that he's the guy for the job...to try to do what he can yourself with a pop tester...you just cant..not worth the time for $25 and he's got them in stock for a hotswap...so here you go.

So $25.00 for a set of 5 ? If that is the case, then yes he beats my price by 50%. As for .5 BAR, that would be around 7 PSI. I would say that is above and beyond what I can do. The best I did was a hair over that, and that took hours. Actually, I think that is somewhat "impossible" to reach since an injector NEVER pops exactly the same everytime and a range of +/- 10 is a killer to achieve. But, as you said, $25 for a set of 5 is a steal. So, $43 x 5 + $25 = $240.00 plus shipping is a super decent price.

If so, then my price totally smokes theirs and my service is up to their specs. I would put my rebuilts against theirs any day of the week. I have received my fair share of injectors from various forum members who just had theirs injectors "done by the best diesel shop in town" ... blah blah blah. They looked like crap when I got them and they performed just a little better than crap. Mine look and perform like new (if new nozzles). Period. If you got used nozzles, they still look like new and perform as best the used nozzle can.
BUT, as I said before a bunch of times, Bosios are the best nozzle IMO.

Also what specs are you getting them to and what do you do for coatings inside and out? Can do you duplicate the diamond plate Kerma puts on them? and he was talking about the inside..getting the distance between the needle and the nozzle into 300 nanometers range...I would love to speak with you via phone about the job to get an accurate comparison between you and Pete.
Please keep in mind, I have no interest in doing this sort of specialized work myself. This is something that I have and will send out to those who are learned in the art.

12-06-2012, 06:26 PM #20Greazzer, how much do you charge to rebuild ONE injector... and how much for ONE Bosio nozzle? Kerma was 20-25 EACH, per injector and the nozzles are $43 each

Mine look new and with new nozzles, they perform like new also. I currently do not sell nozzles but that may be changing rather soon.
Mine are generally at the +/- 25 PSI from the FSM. The FSM permists 50 +/- PSI, but rarely do they leave at the FSM level. I would be interested in seeing how they get down to 7 PSI as they claim.
I dont dip mine in any specail diamond forumala. They are perfectly clean on the inside and out. They generaly last about 1 year before rust actually forms on the outside injector body and its a mild flash. However, I am not sure what happens if subjected to a crazy environment.
As for how I do it, I do not disclose my method or what I use or do. I can say that the cleaning involves ZERO acids, caustic chemicals, or mechical means. I do use an ultrasonic cleaner. The service does take a full 48 hours, however. I do not use electroylsis.
So, that is what I got to say on that.

lapping
If Kerma laps the needle to the nozzlebody he basically makes the gap between those 2 bigger than the factory thought it has to be. Is that good?
Another possibility would be that he manufactures oversize needles himself which he laps in the nozzlebody. For the given price those needles would have to come from china.
Diamond coating
I don´t know where or how he coats the nozzle, but concerning the pressure, flow and temperature at the nozzle/needle I don´t think that will last very long. I even think the ultrahard micro-diamond particles will ream out the nozzle geometry faster than usual when they start coming apart.
And for the balancing
Balancing is possible within 1,0bar, but even if he has the 0,01mm stepped shims I have I don´t believe every set is within 1,0bar. But the only people I know who could check that with a sufficient pop tester is Greazzer an myself. Nevertheless if someone claims that, his setting will still be very good anyway.

I have read Kermas FAQ now
The nozzles are not diamond coated, they are carbon coated which is a totally different process. Also used in modern Common-Rail pumps.
But he also writes the nozzles drift much more than usual in the first 1000miles and have to be reset after that mileage.

I have bought numerous items from Kent Bergsma and his staff, and have found the service top notch, the items were what I ordered and performed well for the price. As far as information, his booklets leave this forum in the dust as far as clarity. But, that is to be expected as he spends time creating his information and the posts on a public forum have to be sorted.
I have his pop tester and rebuild kit and have done half a dozen sets on my families' Mercedes and it has been well worth the price.

I can type almost 100% definitively that MS - Kent really creates no information. He copies info out of the FMS and Bulletins and re-pastes it. That's it. As for the forums, some threads are good and some not so good. As for his ability to create COTS, yes, that is his claim to fame, but that is about it, but you pay for it. At least on the forums, most info is free.

The low cost gauge Kent includes on his pop tester allows you to balance to 25 psi. I have access to high quality lab gauges and simply replaced the supplied gauge with one that allows me to "split 10 psi". I cannot tell the running difference between a 10 psi or 25 psi balanced set. Just balance to 25 psi for road use.

Isn't this what all of you on this forum do? Except it is in a fractured thread that often times leaves holes in the knowledge needed.
FEW of you create totally NEW information on the whole - you quote factory service manuals (FSM), you document your experiences, then you post them. Except it is not in a form that is all that clear.
Many people ask me for information to work on their old Diesel Mercedes and I point them to this and other forums. They come away flustered. I then point them to the Mercedessource site, and many are perfectly happy to pay for the collated and logical presentation Kent provides as well as years of practical information that he communicates well.
Criticize him for his business model. But understand, his business model has allowed him to build a viable business servicing owners who have little to no mechanical skill. I have good mechanical skills. I just don't have time to distill much of the information on this forum when I need it. The few dollars Kent charges for his information booklets are invaluable to me. Along with this forum and the FSMs, I am able to get my work done.
I peruse this forum for the crazy fun fringe factor (FFF) you guys bring to the hot-rodding world.

Shipping is the same if I do 4, 5 or 6.Greaser it sounds like you offer a great service for the price you ask. I'm curious about which shims you use and did you mean you get them to within 25psi of each other or from spec. what is the pop pressure spec anyway? As far as coating them, again, for what you're asking...to paint these things would be a bastage anyway.
Mine look new and with new nozzles, they perform like new also. I currently do not sell nozzles but that may be changing rather soon.
Mine are generally at the +/- 25 PSI from the FSM. The FSM permists 50 +/- PSI, but rarely do they leave at the FSM level. I would be interested in seeing how they get down to 7 PSI as they claim.
I dont dip mine in any specail diamond forumala. They are perfectly clean on the inside and out. They generaly last about 1 year before rust actually forms on the outside injector body and its a mild flash. However, I am not sure what happens if subjected to a crazy environment.

as far as nanometers, that was when we were discussing the carbon coating...lapping the needles? I dont remember that, I remembered him saying he can get the parts themselves layered in super hard forever durable carbon and the clearance between the needle and nozzle to under a micron, I might have misused the word nanometer and likey the distance too. I believe it was something like .75 of a micron ...then he went into the fuel filter thing, right on cue.
I dont know, like I said it sounds right, on both for whats involved. Least to me. I enjoyed talking to Pete @ Kerma, he seemed WAY into it. Like it's all he does. I have no doubt Greazzer (BTW love the Lee Emory avitar photo) in your abilites to do a quality job as well. Experience is key in something like this. Its not an oil change or even a valve adjustment here.

12-08-2012, 08:20 PM #30(12-06-2012, 08:42 PM)Greazzer For a set of 5 I charge $50.00 so $10 bucks each I guess. Shipping is $10.00 and that is USPS priority mail, with insurance and tracking. Shipping is the same if I do 4, 5 or 6.Greaser it sounds like you offer a great service for the price you ask. I'm curious about which shims you use and did you mean you get them to within 25psi of each other or from spec. what is the pop pressure spec anyway? As far as coating them, again, for what you're asking...to paint these things would be a bastage anyway.
Mine look new and with new nozzles, they perform like new also. I currently do not sell nozzles but that may be changing rather soon.
Mine are generally at the +/- 25 PSI from the FSM. The FSM permists 50 +/- PSI, but rarely do they leave at the FSM level. I would be interested in seeing how they get down to 7 PSI as they claim.
I dont dip mine in any specail diamond forumala. They are perfectly clean on the inside and out. They generaly last about 1 year before rust actually forms on the outside injector body and its a mild flash. However, I am not sure what happens if subjected to a crazy environment.
As for how I do it, I do not disclose my method or what I use or do. I can say that the cleaning involves ZERO acids, caustic chemicals, or mechical means. I do use an ultrasonic cleaner. The service does take a full 48 hours, however. I do not use electroylsis.
So, that is what I got to say on that.
LOL.
(12-07-2012, 05:11 AM)Volker407 What I want to say on the technical side:
lapping
If Kerma laps the needle to the nozzlebody he basically makes the gap between those 2 bigger than the factory thought it has to be. Is that good?
Another possibility would be that he manufactures oversize needles himself which he laps in the nozzlebody. For the given price those needles would have to come from china.
Diamond coating
I don´t know where or how he coats the nozzle, but concerning the pressure, flow and temperature at the nozzle/needle I don´t think that will last very long. I even think the ultrahard micro-diamond particles will ream out the nozzle geometry faster than usual when they start coming apart.
And for the balancing
Balancing is possible within 1,0bar, but even if he has the 0,01mm stepped shims I have I don´t believe every set is within 1,0bar. But the only people I know who could check that with a sufficient pop tester is Greazzer an myself. Nevertheless if someone claims that, his setting will still be very good anyway.

I have read Kermas FAQ now
The nozzles are not diamond coated, they are carbon coated which is a totally different process. Also used in modern Common-Rail pumps.
But he also writes the nozzles drift much more than usual in the first 1000miles and have to be reset after that mileage.

as far as nanometers, that was when we were discussing the carbon coating...lapping the needles? I dont remember that, I remembered him saying he can get the parts themselves layered in super hard forever durable carbon and the clearance between the needle and nozzle to under a micron, I might have misused the word nanometer and likey the distance too. I believe it was something like .75 of a micron ...then he went into the fuel filter thing, right on cue.
I dont know, like I said it sounds right, on both for whats involved. Least to me. I enjoyed talking to Pete @ Kerma, he seemed WAY into it. Like it's all he does. I have no doubt Greazzer (BTW love the Lee Emory avitar photo) in your abilites to do a quality job as well. Experience is key in something like this. Its not an oil change or even a valve adjustment here.

They range in size from .05mm up to 1.9mm. The largest I ever used was 1.85. I have no idea who is the original manufacturer.
within 25psi of each other or from spec.
The Turbo is 135 BAR and NON-Turbo is 115. I use a nominal 1,950 and 1,650 respectively. So, they will pop within a range of 1925 and 1975 for the Turbo and 1,625 to 1675 for the non turbo. That's the goal, but add 25 psi and you're still within FSM spec. Keep in minde that injectors never pop the same exact time. If you do a quick pop in succession, you will get numbes all over the place. The key is getting them within this range. Your can narrow the range below the 25PSI +/- but it takes so much time and why bother? It adds nothing to the performance that is really noticable.
what is the pop pressure spec anyway?
See above
As far as coating them,
They leave me with a light coat of diesel. I have them for about a year in my car before they develop a slight flash, but I yank mine every 6 months to test out since I burn grease, so I really never see rust if I stay on schedule. I suggest pulling them once a year for a good cleaning and re-adjustment anyways at the time you do the valves.

Is he lapping the needle and seat? Under the microscope the surface finish is very ruff, and I was shocked to see that after 200,000 miles on a 1978 era Bosch needle that it was unchanged! I expected to see it polished from beating against the seat.
I have read some where that it has been found that a ruff surface helps atomize the fuel, but I may have miss understood what they meant by ruff.
I have thought about lapping the seat, but after seeing it and the atomization idea, I am now thinking that as long as it does not leak, to leave it alone. Sometimes the closer you get to perfect, the worse things work, lol.

I understand the principle and seen all the write-ups with pictures. However, after about 500 injectors, I do not recall ever doing this to one injector. I am not a big fan of removing any metal from a part. When it left the factory, those saucer shaped caps where a certain thickness. Not sure what one gains by removing material, albeit a tiny tiny fraction of an inch. I have never had "leak down" after a complete cleaning. Secondly, and more importantly, I do not mix match injector parts. When I get an injector, all 8 parts stay together. So, however the parts worn against each other over the years, they stay together. Third, I pump it up to 1,500 psi and I don't see the "leak-down" which MS warns about. I cannot believe after 500 injectors I just got lucky. When I see leak down or any leaks, it is because there is some sort of dirt or crud somewhere or it was not torqued at 59 ft pounds.
