    Doing a story on a transplanted Chrysler-Nissan diesel CN6-33, once in a Scout, for a well known diesel magazine. For the life of me, I can't find the pump output in any books I have or can find online. The tag on the Kiki pump says "240cc" but that can't be the per plunger output on such a small engine. Unless it's 40cc per plunger?? It's an NA engine built in 1975, rated at 89 hp, and it was originally installed in an IH test Scout when they were working up the Scout diesel idea. It's no longer in a Scout, however. I'm hoping one of you might have those specs at hand. Also, if someone has the turbo spec, I could use it to compare-contrast. Can't find it either.

    I've got the book for the '80 SD33T put out by IH.

    Doesn't have a "plunger output Spec" but it has a table "Injection Volume Adjustment" with rack positions, pump speed, fuel delivery in cc/1000 strokes and max variation between cylinders in the same units.

    11.8 +/- .1 mm, 1000 rpm, 46.1 +/- 3 cc/1000, 1.5 cc/1000

    10.8, 1900, 43.6 +/-1, 1.0

    6.6, 360, 5.6 +/- 1, 1.0

    12.8 or greater, 100, 29.0-32.0, --

    I think I scanned the book at work and saved the files when I turned in my work computer but I'd have to dig up the disk.

    Joe- Thanks. Do you have any idea what the "240cc" notation on the plate signifies?

    Nope. I'll take a look at mine. I was thinking the total displacement of the pump as you suggested but even then it would have to be for 1000 strokes and it would still be high.

    Mine says "Initial Supply Lube Oil", the same in Spanish, (I think) a bunch of chop suey characters and 240 cc on the plate nearest the shaft end so it looks like a drained pump should have that much added before firing it up.

    That's what I thought. Well, I gotta send the story in and that's a minor detail. Thanks for looking!
