Sometimes I'm really glad I let my indy guy do the work on my '92 300D.
She's way overdue for injectors and the bench test confirmed it. The first
set of 5 factory rebuilt injectors only yielded 2 good units. The next
three only yielded 1. It appears the next batch of 5 will come from
California. Will we get a complete set eventually? Had I just ordered the
parts and done them myself I wouldn't be any better off than when I started
*and* been out the cost of the injectors. I would have thought I could
expect better from Bosch. I guess I'm lucky to have a mechanic who shoots
straight and doesn't settle for crap parts.
There are a bunch of places where you can buy MBZ

At location 3 they had the following:
D1000-39655 Bosch 0.432.217.169 Bosch
Diesel Injector List Price: $206.00 Core Price:
$16.62 and Your Price: $58.89
Happy hunting :-)
Finding them at a good price isn't the issue, it's the fact that it took 13
injectors to get a set of 5 that passed the bench test. I don't have the
dealer equipment to test these but my mech does. Had I ordered up 5
injectors and installed them assuming they were up to spec I'd have 3 of
the 5 new injectors performing as badly as the ones with 200K miles on
them. Pretty pathetic for a company with a reputation for precision (These
were re-manufactured by Bosch, mind you). That's about a 65% failure rate.
How may of us buy parts with a reputable name brand and install them with
the assumption that they *must* be right. Like I said, I'm damned lucky to
have a meticulous mechanic who makes sure it's right the first time.
Wow... that much off? What is his actual way of measuring the injectors?
What were the readings he got?
I installed my Bosch reman diesel injectors... they were way better than my
original injectors... by the smoke test.
I really don't know the measurement of these injectors I installed...
however, I have extreme difficult in obtaining packets of shims to do any
adjustments. Injectors are easy to get but the shims are difficult to find.
I do not want to go to dealer to buy shims by piece.
I have seen many similar reports on the net complaining about many of
the Bosch injectors being bad right out of the box. The problems
I've seen reported are both spray pattern and inconsistent pop
pressure. Seems the feeling is that the ones made in India are the
main source of the problem. It's really hard to understand. One
would think using new nozzles and having access to basic test eqpt, it
would not be hard to turn out product that was decent right out of the
After spending a considerable time researching what to do, I've
decided to do mine myself. I'm in the process of assemblying the
components to build my own pop tester. With that, not only can I
rebuild them using new nozzles, but will then also have the ability to
test them again at any time. Plus, I'm curious to see how the
originals with 127K on them measure up when tested. For nozzles, I've
decided to use Monark.
BTW, for the tester one part I haven't located yet is an old MB or VW
fuel injector line to use to go from the test pump to the injector.
If anyone has one they would be willing to sell, let me know.
For shims, MercedesSource.com has recently added them. They have
them in small bags of like 6 in various sizes, all the way up to a
complete set. They run about $1 for the largest set, more for the
smaller sets. If anyone knows of any other sources, let me know.
Regarding shims, I have a question maybe someone here can answer.
When adjusting the shims, is it OK to use two or more shims to make up
the correct thickness or are you only supposed to use one shim?
Reason I ask, MercedesSource is selling some very thin ones and
advocating that as a way to more easily get the right size without
having to have a whole family of them. But I'm left wondering if you
one or more very thin ones, isn't there some risk the thin material
could break apart?
Great site... thanks! Did you know they have complete bench tester kit?
It looks like they made their own line... easy... 1/4" tube... with the
crush coupler and the respective nut... These all should be able to be
ordered at grainger... or McMaster-Carr website... but you want to be able
to physically fit the part before purchase... try plumbing store. or even
home depot for the valves you use in bathroom for toilet... or their loose
packet parts supply.
