I believe that you are providing a needed service to forum members at a fantastic price.

Simply ignore anyone who judges this service without even attempting to use it.

Let them pay $20.00 per injector at a proper diesel injection shop.

I'm sending mine tomorrow.

How difficult is it to get the injectors out ? My bro in law said I need special tool for the leak-off connections because they are pressured seals. Is this true ? I know he BS me sometimes.

Its easy...
The "leak off connections" or "return lines" are just press on lines.
If you remove your injectors, plan on replacing these lines.
Order the right MB stuff from a dealer or online to replace it. Otherwise it will leak if you don't replace it or go with a crap brand

What's the price on new nozzles? I just may go that route when I ship a set.



Does anyone else remember Doktor Bert speaking of increasing injector pressure for more power? I do, simply don't recall what all was included.

I think it involves a better spray pattern equating to a more even burn equating to a probable increase in power.
He did so much to his car at once it would hard to say the gains...
Thought next time I am setting mine about 5 bar ove spec most likely to even out the pattern.

I can't give a across the board price for replacement nozzles. The price will vary from model to model. I think they will be in the $25-$30 dollar each range. But don't quote me.

Hey,
I was pricing out the parts for injector cleaning found in this tutorial here:

http://skinnerbox.steaky.org/Service/W123/w123CD2/Program/Engine/617/07_1-137.pdf

I asked for a price on the cleaning kit, the cleaning needle 0.13mm, and the cleaning needle 0.18mm.
Fastlane sent me back a price for only the cleaning kit for $229. I was wondering if anyone knows anything about this kit. Do the cleaning needles come with it?
I was thinking about buying it and putting it in the Tool Rental Program we have here but I would like some more information on it first.

Nobody???

This would be a nice addition to our Tool Rental Program.

Does anybody here work for Mercedes or have any contacts that can look this up and see what this kit contains?

This is great. If you are going to clean those holes and set the pressures for $3 each this is too good a price to refuse.

Are you using hardened shims to set the pressures? In a recent thread some were advocating the use of soft washers to set the pressures. Too much stress, oscillation, vibration to use soft shims, they didn't harden them for the fun of it. Those shims get hammered.

dannym,

This is the Bosch kit; essentially the same.

I have been using the orginal shims out of injectors that I have taken apart. I talked with my nozzel supplier today about a set of nozzels and shims. I didn't ask him if they were hardened. I would think they are. I will ask him on Monday. He is pretty sharp and rebuilds more injectors then I have ever seen.
I don't have one of those fancy cleaning kits. I don't think the cost justifies the benefit. You can ream out the seat all you want. If the needle and seat are worn to much they won't seat properly. You will be able to make them work better. But they won't last. I have tried. I soak the nozzles in a cleaner designed for the HVAC industry to break down carbon and fuel deposits. It does a veary good job. I use a set of carb jet cleaners for the holes.

Shims from a supplier of diesel injection parts would certainly be correct for the application. Those other guys were using washers from the hardware store and grinding them to thickness. Sounds like you are on track to build some good injectors, thanks.

I had a rebuilt engine installed in our '85 300D about 2 yeras ago. At that time, the injectors were serviced. When I got the car back, the injectors were leaking at a joint in the body. This was fixed at that time.

But now, I see damp areas aroung two of the injectors and some light colored dripping on the garage floor - I think I have same problem again.


What causes the injectors to leak - What does it take to cure this?

The craftsmen 27mm deep sockets seem to work well pulling injectors I have used several different craftsmen sockets and all worked well. The Bosch kit on eBay is a fair deal. But realize unless you have real good vision you will need at minimum a lighted 5X magnifying glass or better a 10X microscope. The kind of carburetor cleaner you buy in the gallon can cleans them quite well if you let them sit disassembled for a week you must use car to keep all the injector parts together don’t mix up the parts especially the pintal and seat or you will not get them to work well. The preferred method of cleaning is to use a ultrasonic cleaner and some professional grade aqua cleaner but the ultrasonic cleaners are not cheap and it is hard to get the good cleaning solutions from the distributors in small quantities gun stores do however sell adequate cleaners. I would easily pay $7.50 each for cleaning and reassembly in bulk lots of injectors. Doing it for under $4 each is theft of someone’s labor take advantage of it while you can. Injectors are marked on the top half with how many bar they are 115bar for non turbo and 135bar for turbo diesels far two often I find them in the junkyard with the wrong injectors in them at least 1 in ten cars has an injector missing parts it is just scandalous the crap some shops will through in a car. Last but not least if you are getting a set from the bone yard most have been rebuilt at least once by now and they don’t care what the injector is stamped for the bar rating because they put a little black rubber band on them covering the stamped markings these come off over time so just because the top of the injector is stamped 135bar does not mean it is a 135bar injector. Last but not least at least on the west coast where the vast majority of the cars at the bone yard have well over 200k miles on them most nozzles are bad so you really need to sneak a tester in to check the spray pattern or buy the return policy or you will spend a small fortune on bad injectors. TOMJ if you read this I hope you are doing well if you are going to give up completely on injectors I would be interested in some of your equipment unfortunately my finances are iffy now to but I could but a couple hundred dollars at a time but I hope you are well things will improve.

WOW!! Thanks. I hope your not bidding on it because I am going to.

Concerning the ultrasonic cleaners. I think an ultrasonic jewelry cleaner with carb cleaner in it would probably work well.
You can get them a stores like WallyWorld or K-Mart for around $20.
