I've had to get more than a few Mercedes with K-Jetronic running properly without factory rebuilds. Monitoring fuel pressures on either side of a diaphragm because that REALLY matters. It's the main control after the fuel slits. By slits I mean actual slits. The air flow meter "plug on a stick" moves a piston up or down in a slitted cylinder allowing more or less available fuel.
And if you've had any fuel quality issues, like perhaps... Ethanol. Or any other contamination LOL get fucked!
I might be telling you what you already know but I had to fix them by utilizing thousands of slides of Microfiche. For fucks sake. All that shit belongs in a museum or a collector's garage. Not in the garage of the average Joe or a grandma with sentimental value.
Yup.
I haven't worked on a K-Jet for some years (other than routine stuff). I'm getting ready to put several ca 1980 VW water cooleds back into action and dread discovering that a fuel distributor is mung. I can rebuild the control pressure regulator but I never did serious work on the FD and hope I don't need to. Just in case, where did you find the data on rebuilding?
Within the Microfiche. The shop owner was an old school german car guy because that's what he had worked on in the past. The Microfiche reader was a backlit screen projector side by side with a cathode ray oscilloscope on one of those huge diagnostic center roll around things.
Y'know. The things everybody junked because they were obsolete and just taking up space. Good luck finding that kind of stuff.
Most people think you're talking about a small fish when you say Microfiche. And I'm not even that old, early 30's.
I have an old Sun scope in my (hobby) shop. I've used a fiche but not for car docs. We had print manuals and right as I was getting out of the business, AllData on a computer. Perhaps some day I'll run across the Bosch rebuild info online. Cheers!
