Repair injection pump own hands.
Diagram of pump
Long wanted to write, but all hands did not reach...
In General, it all started with the fact that looking at the car from below, I saw that the entire engine not G...... At the time I owned the car for exactly 5 days, and of course had no idea what it is and how to treat... First climbed in an Internet, on forums, by itself, drive2, with questions and cries for help... All with one voice asserted that flow from the injection pump, and this disease is treated by replacement of REM.kit.
I ordered the same kit from BOSCH that his number is F 01M 101 454, else the o-ring on the tube polymnie A 601 997 06 45. Having their body shop, which is 500 meters from my house, I decided to remove the pump in the yard near the house ))))) the weather was terrible, autumn, snowstorm and wind did not give me bored )))) the extraction Process is not even complicated, it is necessary to Unscrew the three screws with the TORX head. By the way anyone interested in the threads on the bolts M7! Yes, Yes it is M7. So carefully, don't lose them in any case.
This is through these holes is secured the pump to the engine. It bolts M7 ))
Unscrewing the three bolts, I'm your straight arms pull the pump itself... and broke the plastic tee of the return...Pouring their face and a brand new down jacket a comrade standing next to me ))))
Then I said to myself a few kind words decided to go to the Studio there and continue working )))) Not to immediately on the machine to stop in and warm the whole thing off...
Then everything is simple.
Secured the pump in a vise. A 40 TORX key Unscrew the lid, it is mounted on 4 bolts
TORX 40
The same cover. Their 3 pieces.
First, remove one lid, just after when beneath it all has been replaced proceed to the second.
After removing the cover we see a picture here
Cover on the reverse side. O-ring (is the one that is leaking), metal gasket and two rings in the hole on the right. One plastic, the second rubber. Seats do not mix!
Nothing complicated here, just everything changed.
The pump under the hood. In the big hole is the piston pair.
By the way, so that no dirt gets where it is not necessary, close all openings with protective caps in the kit are present.
Protective caps
After the cover replaced all gaskets, proceed to the replacement in the pump. To do this carefully with pliers to remove the connector, tried to do it through the protective cap, but it did not.
Under it are two rings of plastic and rubber, they are also replaceable without confusing their places.
Sealing rubber ring.
and resistant plastic
We put it back together. And proceed to the next cover... And so three times ))))
And Yes, on a broken plastic tee. Lot Internet shopping, I realized that the tee is not sold separately and only sold with fuel tube... It the price is about 2700... Clenched teeth, I ventured to order a different handset from another Mercedes without the tee... That is, without discharge pipe on the bleeder valve. Here is my tube A6120703232, and I ordered A 611 070 32 32. Accordingly, in its form, it did not, but to put it a little bit and turning down a little bit to stretch the other way.
This is such a tube... And should be with tee and outlet tube to the bleeder to razbazarivanii fuel system.
By the way, when collected, mixed flow and return reversed, and the pump is obviously not like )))) and then put everything in its place... Razvozil by loosening fuel pipes from the injectors and twisted until the flow of diesel fuel.
Dry, but still dirty )) Looking for a wash that has a pit or hoist to the bottom of mill to wash... Will replace all fluids, but not yet convinced (sure) that nothing is running, will not change.
Yes, understood everything correctly. It is possible, in principle, sealant, honestly even thought this was not ))) I don't know what will.

There seems to me a engineering trick ))) As don't hold these cap bolts, still there is a gap, due to the fact that the pad is too thick... this will be the gap stuffed a lot of mud, in consequence of which starts to flow... )))
If we talk about the engineering tweaks, then I would call it differently: Engineering Greed. The calculation of the dealer that it will regularly drive the owners to repair the injection pump. As you can see, the engineers miscalculated. If I understood everything correctly.
With the sealant will be "deaf" option? If all the fluff in order to avoid? (on the outer perimeter fit On)

Well done! Good job! But I still shlifanuli each pump cover. During disassembly it was found that none of the lids is not smooth plane.
OK ))) Today I have washed the engine finally! And found that the gasket from valve cover also oil toplimit... soon there will be another photo report )))
don't know whether you have the cutoff valve from fuel pump or not. I have here it is not. and handset what's in the photo like for valve just. and number respectively. here is a photo.

so had to muchatsya.
Not quite. Main pump is a pump that keeps the fuel from tank to injection pump. The pressure in the fuel rail is created by the injection pump.
Main pump it is called. It only creates pressure in the fuel rail and injectors. Fuel injection is an electronic control unit by feeding pulses to the injectors. It seems to be a simple system. But the unit requires treatment for YOU. The surge in onboard and ready soroket for a new ECU.

How many in the service asking for such work?
Repairs came to 100 Euro. With removal and installation.
I have it removed easily. For withdrawal there is nothing. But one said service process and spare parts 250. In another 100 Euro, will go there where 100, let's see what there final price will be.
Recently, I was shown photos in which there are round pads. Only Mercedes is the same as me almost...
Do the same for the santa fe classic 2.0 crdi, the same model injection pump(only the o-ring). Nothing complicated about the replacement of no, the power of each, the main thing is not to lose anything during the Assembly, especially the small washer on the lid.
Did repair of fuel injection pump for Iveco daily.
All the same, even replaced the two oil seal on the shaft and the shaft itself.
Because the glands sharpened shaft and went chips.
The injection pump was about Leman.
No, never heard such a sound...
Sometimes there is a knock when starting the starter, I don't know what it is and where it is.
And there is the sound of the keychain in my pocket more often when warmed up. Maybe the shaft has changed. I like this connection strumming.
On the shaft production, but there are on a leash that is worn on the drive shaft.
can't consider the condition of the drive shaft. It has to develop. Is there a metal clink when you work?
and I thought that the plunger pumps is an ancient technology of the 60s! and then there is even Mercedes he uses it!

Plunger ( 3) at 1200, 1500 shaft, repair kit 700. 5800 total the parts and labor ( usually 3000 running on the stand). Roughly 9000 RUB what is not economically profitable? Better than new for 30000? With waiting a week?
Yes, and if the plunger is clear of what their roll in the machine, the volume flow is not necessary to set

you only replaced seals and rubbers .repair means the restoration of all the parameters laid down by the manufacturer .I thought it was .10 years of work in the fuel area and that is what we took money
to me in my injection pump, but the climb, flow left, and even the injector sopivat periodically, I don't even laziyu there, not much yet, but all in the nozzle.
That's another story ))) you have the injection pump of the distribution type, i.e. atomizers mechanical. I have a common rail system, injector solenoid. Can't help sorry
Hello. Interesting article, I bought a Mercedes 123, 240D still not sure what happened but said need injection angle on the strobe vystovit as it podtraivaet at idle. Maybe there came to the end of the injection pump ? Is it possible to fix ? Diesels for the first time stalknulsya. Still it not start because the starter broke and he is right now in repair.
Hi! Interesting article! I also stalls at high speed, I will look for a siphon where )))
Buddy I also faced the problem of broken tubes and air suction through hardened rings in asiamah, and the tee and valve?Tin))))
Look how I did)))
The fact that reliable and cheap)))))

Good luck, nothing complicated, in principle. only 3.2 harder to remove it because of less space
Nope, do not tell ((
Earlier on the computer sooooo much information, it was on repair, now sojeleniu nothing... On the forums need to shop
And immediately tech or spasta time? And then a friend said that there is DBB REM the kit and some of their quality shit
Can't say how, because the pipe from my engine. This tube is directly inserted, but had to bend it.
Hi, please tell me, do you happen to have a close-up of that part of the tube in which the high-pressure pump is inserted? Does nipomo there straight fitting or at an angle?
