BOSCH C.I.S JETRONIC FUEL DISTRIBUTER REBUILD, Mercedes & Others

Hey guys and welcome back to the channel.
This a classic rebuild of the infamous CIS fuel distributor, all explained in the video straight forward process, extra cleanliness measures must be in place.
There are two famous sources for buying the rebuild kit:
www.Salvox.com
cis-jetronic.com
I went with salvox as recommended by friends.
However the other company had a better documentation of the process:
cis-jetronic.com/public_doc/0...
Enjoy the video

One of the best tutorials I’ve seen well done and thank you 🙏 not a job to be rushed it’s w201 heart surgery this 😮 look forward to watching your other videos on the back of this 👍

You guys have just helped get my 560 SEC running!!!! Thanks so much for the video!

What a car!

[@Fernando-Garcia0685]

I am about to do this on my own, so your video was extremely helpful. Thank you! 🤠🚑

[@ikerelorriaga1867]

whoa, thank you very much for sharing this disassembly, even more with the comments and the tips, This will be very useful for many classic fans

[@pierresimenc2343]

Excellent tutorial. Thank you. I always put the O-rings on the spring before putting the springs back to the hole. This also works, maybe even a bit easier.

[@TheWinezen]

That is one detailed and extremely educational video.Thank you so much.

[@krishnashanmugam6685]

Hi, your vid/tutorial was excellent. One change I did though was that I installed the metering barrel for the control plunger into the upper chamber first before bringing the two halves together (after installing the new diaphragm and seals etc.). I found if I did it like in your video, I ended up ripping out the o rings on the barrel. It was far easier to guide the barrel into the upper chamber first when I could see the o-rings and adjust as necessary to get the barrel to slide in without problems. The barrel still sits snug on the lower half of the distributor after bring them together and tightening the barrel nut down pulls it in tight anyway. I do have another problem though and was hoping you could offer some advice. After my rebuild, I could not get differential pressure with both control and working pressures reading 6.4 Bar. I actually tore my distributor down a second time to see if I had done anything wrong but it was all good. I then had a good look at my EHA valve and noticed that mine was a clear hole going into the EHA. Online images though show something there. Is there a restrictor present? Your kind advice would be appreciated!

[@michalkarol2959]

Great job! Do you know if there should be a 12v on the distributoer plug when I turn on ignition car key??

[@michaelrush8038]

Question; when setting your air flow plate stop pin, do you use the front of the air flow housing or the rear of the air flow housing to align your air flow plate? KE plates are at an angle, so front and rear are never at same point as far as aligning with inner ring of housing. Using front of car as front of plate.

Do you use anything for locking threads of plunger seal screw? I did a new o-ring to solve a leak there, the leak is solved, but the seal screw changes after some time of driving! I set it to .6, then later the car starts driving funny and I find that the screw is now .52.

[@usarover]

What product do you recommend when cleaning these components? Thank you for this video, I'm about to do my 190E 16V.

[@TheFlyingMechanicDIY]

I use brake parts cleaner, and in the last step i use carb cleaner .

[@mansouralblooshi3004]

Hi thanks for sharing this clip Why it is necessary to do this job? In other words what are symptoms of a failing fuel distributor?

[@TheFlyingMechanicDIY]

The symptoms are usually uneven running or misfire. But these symptoms can be due a ton of other reasons, so to point to a fuel distributer, u will have to jump connect the fuel pump to run continually with the engine off, remove all the injector lines (8, 6 or 4)from the top of the fuel distributer, there shouldnt be any fuel coming out initially from any of the ports, then very very slowly deflect the air flow plate and fuel should raise EQUALLY in all ports equally. If the fuel distributer fail any of these tests it should be replaced or rebuilt. هلا اخوي منصور

[@belmethos]

Hi what would be the torque values for the torx screws?

[@javi8939]

Just rebuild mine, I had to adjust it to 0.4mm, CO perfect, if I set it to 0.6 CO on idle goes way up, 7-8%.

[@hollyroper1637]

I couldn’t tell what he was measuring when he said that. What needs to be at .6 mm?

[@micmac9853]

if the upper chamber is removed will you be able to blow air into the injector ports? i dissassembled mine since no fuel is flowing out of the ports even when the airflow vane is depressed all the way down..strong resistance is felt on pressing down even with ignition off.new pump and filter was instaled

[@GMPLDR]

Were u able to get it working? If yes how so?

[@hommerj8791]

hola amigo tengo un 1991 560 sel mercedes benz con el mismo problema de distribuidor de gasolina estoy en mcallen texas tu tendras algono en venta o decirme quien podria ayudarme con ese problema por el area gracias de antemano

[@terrwyn-1610]

Hey, what height settings should start with the lower adjustment screws? Asking for my step dad.

[@TheFlyingMechanicDIY]

They dont have a pre setting, i leave them as it is, and if calibration required then it is done on a test rig, by measuring flow of each chamber

[@xaviergonzalez5145]

Lovely video! My 260E 1992 has a extremely poor fuel economy, what do I have to check first??? Thank you!

[@TheFlyingMechanicDIY]

With ke-jetronic u have to start with the electronic system, read duty cycle faults and blink codes if available, see what faults are in the car.

[@xaviergonzalez5145]

@@TheFlyingMechanicDIY in my case I got an electronic system but no KAT. So I don’t have a closed loop emission system. I am concerned about EHA but is expensive. Something more to check???

Wo bekomme ich die Daten her wie tief der Abstand vom Steuerkolben unten sein muss? Du sagtest bei deinem Mengenteiler im Video 0,6mm. Ist das überall so?

[@TheFlyingMechanicDIY]

Yes same. Read links in the video description .

[@Erikug2]

I find this piece of automotive technology truly amazing (more of a fan for the basic K-jetronic as its more mechanical). However I wonder if it could have issues more frequently because of the rising ethanol concentration in today's fuel. Do you have any observations regarding this?

[@TheFlyingMechanicDIY]

We do not have ethanol in our market, but i would say as long as the fuel doesnt set there for long times then it should be fine

[@paschalnyamogo6959]

You can also use Lucas ethanol conditioner everytime you fill up

[@archygrey9093]

Ethanol does affect the original gaskets, as does sitting dry, but most distributer rebuild kits should come the ethanol resistant gaskets now.

Is there any chance I can mail you my fuel distributer for a rebuild? would really appreciate a reply.

[@TheFlyingMechanicDIY]

I appreciate your trust .. i would love to help, but i have to reject remote repairs cause its hard to tune these without the car in hand .

[@egbertgroot2737]

How is the timing of each injector done? I miss a link between engine/piston position and fuel coming from the CIS

[@TheFlyingMechanicDIY]

It is continuous fuel injection, there is no timing .. old days when fuel saving was not an issue

I dont believe this is normal for any CIS fuel distributer

Tks for reply

Turns out the Rolls Royce fuel distributor only has springs on one side finally got it all done

[@lesdmark]

@@andrewdrevdahl2329 The fuel distributor he is rebuilding is for the KE jetronic system. It has a upper and lower spring however the regular K jetronic and K jetronic with Lambda only have a spring on one side. This is for anyone who sees this comment in the future and asks the same question.

I wouldn't recommend cardboard for your build surface. There are tons of fibers to get in the assembly.

Why? He just used it to speed up removing the screws no harm done doing that. He broke them loose first by hand.
