580SE Lucas Injector Leak

I hope it's the same, I just ordered it lol. Are there any surprises swapping them out? Springs hidden somewhere? Anything weird?

Where did u buy the line & how much was it.??
I know a guy that needs one.. cough, cough..

Hey Mike, I forgot to tell you I got one for $24; $11 for the line and $13 shipping from Wengers, and that's all we'll say in public on THAT subject!

They aren't the same.. if u notice on the "new one" the connection is flush w/ the top of the pump where your "old one" has an adapter that raises it about 2 inches.?? I hope that's just a bad picture.??
Oh Wait.. I seem to remember that adapter comes off..??

Good deal Mitch.!! I hope everything is nice & dry now.??

I searched and searched and there isn't an identical match. It's the same part number as the Case parts diagram calls for, so it should be good. Yea, looks like both lines have an adapter. You'll have to do the same thing with that vent line, there's another piece on the end that screws off.

Hey thepumpguysc, guess what?? Bad connection on the cutoff solenoid. It was intermittent. Fixed it, bled to the screw, and she fired up thank the Lord!!!!! But she died when I took my foot off the gas, how do i adjust the idle?

Idle speed doesn't change on it's own, you still have fuel problems.

Where's the don't like button Delmer?? ‍
I only had a few minutes to play with it, I was just happy it started! Tomorrow I'll replace the primer pump and hopefully that'll solve it.

The idle adjustment screw is on the top cover.. duh..
BUT DONT adjust it until AFTER u change out the lift/supply pump.. & give it plenty of revs up & down to get rid of the air.
It probably died because it cant draw fuel that far at such a low rpm{low idle}

Hey pumpguy, what's the hook on the back of the primer pump go under?

OK..I'm done.. anybody else, feel free to jump in..

I thought this forum was to help each other out, but I guess not. No worries, I got it figured out. Thanks for all your help pumpguy.

IT IS.. but I told u along time ago u have no business holding a wrench.. & to walk away.
but u keep dragging me back in..
Its a SIMPLE take OFF & bolt ON.. & u have to ASK how to do it..
YOUR THE ONE who said you were EXTENSIVLY VERSED in rebuilding tractors BUT didn't know what a shut off valve was.. a hand primer or a supply pump was..
& NOW u wanna know where "the hook goes" on the new supply pump..?? dammit man..

I been holding a wrench for almost thirty years. This is my first diesel. Also, I've been under extreme pressure schedule wise to get this done which has me not thinking 110%. Not to mention I have a full time job I'm working too. I just needed some extra help here and there to keep from shooting this stupid machine. There was a reason why I asked about where the hook went, it actually wasn't a simple bolt on, and that's why the old one wasn't working. I figured it out and now it's working 100%. Also, I know what a fuel shut off is. I didn't care about the one on the pump, I was talking about the main shut off that comes out of the tank. That allows you to change the inline fuel filter with out running it out of fuel. There is one, it's on the parts diagram and I found it. I'm sorry I've been so frustrating, I'm not totally stupid, just new to diesels. You do this for a living man, I had to learn as I went. But you know what? This machine is running better than when I got it and went from 7 leaks to 0. I'd say that's pretty good for someone who has no business holding a wrench. Thanks for all your help, I'll look elsewhere for help and fellowship in the future.

What happened that it wasn't a simple bolt on Ed ?
Help and fellowship is abundant here.
Don't be so hard on pumpguy. Reread your thread. He gave you a LOT of professional advice that you won't find anywhere else !

It wasn't my intention to be hard on anyone. I appreciate everyone's help more than y'all will ever know. I was put in a tough position fixing this machine, under a tough time constraint, AND it was my first diesel. It just sucks to be put down, to be told I have no business holding a wrench, when you guys don't know me, you have no idea what my abilities are and what I've accomplished.

The old pump had no resistance on the lever on the machine, so I assumed it was bad. Once I got the new one I took the old one off and it worked fine off the machine. When you push the lever the hook in the back works. So that made me think it was installed wrong. I went to the parts diagram to see exactly how it interacts inside the motor but it doesn't show me that. I put the old one back on and again there's no resistance on the lever. I simply didn't understand why that would be. So I figured the hook was in the wrong place inside. Is that not pretty sound reasoning? Anyway, I left the old one on and it's running just fine, way better than when I got it.

Strange things happen when replacing lift pumps. Did you compare the two of them and determine if the angle of the arms are identical and the exact same length ?
What you describe leads me to think the lift arm is being held in the upstroke position for some reason. When the arm is off of the camshaft lobe there has to be resistance on the priming lever. If there isn't something is wrong.
It is not unusual to buy a new buy defective pump either.
Also it is very normal for the camshaft lobe to be so worn it will no longer lift the pump arm. Although that isn't a cause for concern in your situation.

The new one actually was defective. I did install it just for kicks to see if it worked in place of the old one. After a few pumps one side broke, so if I do end up replacing the old one I'll definitely get a different brand.

So I'm using the old one and it runs fine, just doesn't pump. Please bare with me, I'm going to show my ignorance on diesels... when the pump is off the motor I see a silver rod through the hole. I assume that's the camshaft right? The hook on the back of the pump, does that go above or below the rod? That's where I got confused and that's what I was trying to ask pumpguy. I don't think I can get the hook under it, I tried inserting it 90' and turning, it didn't work. And it makes sense that the lobe raises the arm and makes it pump right? When it's on top there's no resistance in the lever, so that's why I'm confused over it.

The arm on the priming/transfer pump goes against the camshaft, I've never noticed one that would go both above and below, I suppose it's POSSIBLE. The arm is usually formed steel about 1/16" thick bent into a U, the flat part of the U goes against the camshaft, it should be worn shiny where it touches the camshaft. If this description doesn't fit, then the flat part of the arm still goes against the camshaft.

Was your new pump the same way with no resistance in the lever installed? uninstalled? Also the cam has to be in position so the arm is not on the lobe for the hand priming lever to work.

Thanks Delmer, that's exactly the description I needed. Honestly I think the new one was crap to begin with so I'm unsure. What you said about the cam being in the right position for the lever to work makes sense. I think that's why it didn't just bolt on too. It's pushing up on the arm so there isn't anything for the lever to do. The question is, how do I fix it?
