Looking for KTA and some help

[6LCummins]

So i have been tryin to figure out my injection pump out. I have a 1990 12V out of a Case IH 5140 in my truck and i dont wanna touch it til i know wat im dealing with. i have had a couple tel me they have never seen my pump b4 so im kinda iffy on touchin it, but was told if anyone knew wat it was or wat to do KTA was the guy to ask. im linkin another site cuz i dont know how to put pics up here. sorry if it breaks the rules.

That's a VE alright, looks like the one we have on our Case 4240. It looks a little different because it doesn't have an AFC or KSB. That means you won't have a pin to grind, an AFC lever to remove, or a smoke screw to mess with. The only external adjustments appear to be idle, high idle, and the power screw. The power screw should have a 13mm nut that you can loosen, then turn the screw in.

It's clearly visible in this pic: http://www.dieselbombers.com/attachment ... 1179356174

It's right above the throttle linkage (in the pic) and under the return line that comes out of the top of the pump.

So ur tell in me i cant use a fuel pin??? and thta the only thing i really need to mess with is a power screw??? some of those sound really good, i hope it doesnt mean i cant use a fuel pin. i havea free one gettin made.

Oh, well, heck, I can take that one off your hands...

[KTA]

I cant see the pics, but it sounds like everyone else has already told you correctly.

[6LCummins]

So from wat im gettin i dont havea fuel pin in my pump??? am i correct in thinking this?

And Begle if u find me a P pump conversion ill trade ya.

[KTA]

That is correct you will not have a fuel pin with no AFC housing. Your adjustments will be limited to the high/low idle screws and max fuel screw. You can also change the governor spring too. That pump would behave basically like a pump with a ground foot and pin only it will full fuel all the time with no boost refrence.

[Greenleaf]

No boost reference.......ahh..........remember the days.

I figgured no AFC worked really well on the old Roosa and so I converted my Bosch

THat pump shpuld work out just fine. Kinda like the old days prior to EPA/CARB

So that Blows azz. wat all do the idles do for the truck??? and i kinda know wat the power screw does but wats the benefits of playin with that?

Almost self explanatory, High idle limits top rpm and low idle tells it where to idle. Benefits of fuel screw? more fuel.

[PToombs]

If you turn the fuel screw in, you will have to turn the idle down.

Yea i know they are pretty self explanatory but i wanna make sure b4 i go mseein with it. and why would i need to turn the idle down??? Would it be good to turn the idle down in winterr to help it run or to turn it up a lil?

When you turn in the fuel screw, the pump injects more fuel across the entire spectrum, so it results in an increased idle. You got to dial the idle speed back down with the screw.

And while you're tweaking, you also need to watch out for runaway so the engine doesn't explode.

oh.....and then grin from ear to ear as it sets you back in the seat.

ok greenleaf, i know you've been running with the afc disconnected for a while. my question is aren't the non afc pumps designed to operate on fixed rpm equipment (pumps, generators and such)? if so how do these pumps accomodate for fuel enrichment at varying rpms such as our engines. i understand that we have timing variation accomodated in our pumps but how does it regulate volume of fuel injected per event? if its optimum at say 2700 rpm wont it be way to fat at 1800?

i know its probably simple but the older i get the less flexible my mind becomes. it's getting harder every day to wrap it around things .
