VE Pump
 

So i have never had to play with my pump because i bought it already turned up. so i was wondering just where are these screws to play with??? i am one that doesnt just go turn things and see if it works, i wanna know which ones are the right ones to play with. im thinkkin bout turnin the smoke up a lil bit and maybe the power scrwe too. but they also might get turned down to save on drive train and fuel.

Well you can talk to Brian(KTA Cummins) over on 1stgen.org, he is the best in my book. Here is a link to help you out though.Look here

you probably already have the smoke screw turned in all the way and probably the cone ground since you have a 3200 spring already. So maybe the full power screw ain't been toyed with.

Phil, not bashin on ya but how do u know i have that stuff done i dont even know wats done to the pump for sure since ive never had it apart. im not sure the screws are all the was in cuz from wat ive seen all the screws i could think would be the ones have pretty good amounts of thread stickin out.

here are some pics i just took of it, cuz it doesnt really look exactly like the one in the diagram.

That doesnt look like any VE I've ever seen. What is this engine out of?

yea you want to get the numbers off the pump or the engine or something. It looks like a ve with the aneroid off the top or whatever the ufo flyin saucer lookin thing is. I don't see a place for the smoke screw. Hey nick remember that video last night I showed you? The smoke screw is under that little silver cap. http://s28.photobucket.com/albums/c2...t=MOV01023.flv What that thing does is control the amount of fuel given to the engine before boost is built.

well you said you could get it up to 100 mph. You're not gonna do that with a stock spring in the ip. So I just figured that most of the stuff that changing the spring entails was done with already(smoke screw and fuel cone)

depending on the gearing and trans you can get over 100mph with a stock VE. Mine just had the fuel and smoke screw turned in and I would push 105mph with it.

This is wat i found out:
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.

and with a NV4500 and 3.54 gears i got 4th gear to top out at 95

I'm sure its toungue was hanging out pretty good.:y:

you people suck. really really hard.

Well, DUDE... Isn't that something you could have said earlier?



There doesn't seem to be an air fuel control on top of that pump; I think that's a fuel banjo-bolt at the top, right? So consider that your AFC settings are all already maxxed out. So that leaves a full power screw, timing, and a governer spring that you can modify.

Of course, since this is a tractor, it means that it'll be thrashed on a daily basis and you need to be extra careful to not overload anything on the driveline. And you also need a pyrometer.

Begle......its in a 1988 C30 1 ton Dually. pyro is in, and not sue bout governor spring or fuel screw but i might play with it tomorrow:D

Ohh... This is your daily driven truck?

Yikes; I'll bet that thing is a freight-train-level smoker if you put it to the floor, isn't it? The tractor was probably a hand-throttle?

Do you have a tach? The pump might have a 3200 RPM spring in it stock. If it even uses the same type of springs, which I'd assume it does.


What's the rest of the driveline in the truck?

the pump that you have on your truck is a lucas injection pump.

Why do you say that? Lucas builds Boschs? Rebuilds Boschs?
