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

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

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

You lost me when i saw the power drill....

Thank you.

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.

I have a 1991 Mercedes Benz 190e 2.3 4 cylinder I’m about to rebuild the same exact thing on my car do you think it will help the running of my car if I rebuild the fuel distributor on my car???

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.

Friend, how to adjust the mixture adjustment for the nozzles?

Hey guys , where I can buy all that seals? Maybe somebody have link. Appreciate that

Please don’t use Silicone on any vehicle with a catalytic converter, your contaminating the O2 sensor AND the Catalytic converter…….and causing a new drivability problem😂
Thank you for your video.

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!

great video..... thanks
