I was running my 580E just fine, but when I shut it off it now won't start. I looked and noticed the injector pump linkage came unscrewed. It just died recently for no reason and I was able to re-attach the linkage and it worked, but now it won't. Seems like there's something inside the pump that the little shaft isn't engaging with or something? Someone must have worked on it a long time ago and used a die instead of a nut for some reason, but it worked like that for decades. Here's a picture: Can you take the top off while it's on the tractor and see what's wrong with the linkage, or do I have to pull the pump off the tractor? I think it's a Delphi pump.
Now THATS one for the books..LOl.. Under the "die" is the throttle shaft.. the shaft is flatted on 2 sides & it fits in the "slot" on the LEVER.. It probably came out of the slot.. not a big deal.. Yes its a Delphi DPA pump.. ALL the nuts are the same, so if you go/call a fuel shop to get one, they'll know whatcha need.. it looks as tho the throttle shaft is broken?? so you'll have to remove the cover to replace. YES, it can be done inplace w/o removing the pump.. Your looking at about 12.00 for the gaskets & orings, 25.00 for the shaft + shipping. I need the pump # to tell you the correct throttle shaft #..
Thanks for the info Here's the data plate, I don't know which number would be the most useful: So do you just unbolt the top cover and pull the little doo-dads out that need replacing, or do you need a Swedish tool made of unicorn tears to get it apart without breaking important things?
Sorry for the late response.. lost internet for aday & 1/2.. The thr shaft p# is > 7123-77L but requires a new bushing, p# 7139-433B The new thr. shaft is sturdier & wont work w/o the new bushing.. Theres thousands of write-ups on how to get the TC off & what to watch out for.. most written by me..Lol
Okay, I managed to get the parts thanks for the help @thepumpguysc and put them in. Here's what the inside looks like, in case anyone else is doing this: When I got it back together it ran good, then died about 30 minutes later while driving down the highway back to the shop :/ It seems like the injector pump is just starving for fuel, so now I suspect the mechanical fuel pump on the side of the block, I guess it's the next thing I have to replace to track this down. Weird, because it'll run perfect for awhile and then die in a way that you have to hook a chain on it and drag it home.
Yup, filters, lift pump, something in the tank, electric shut off solenoid going out.?? Replace the first # in the P# w/ a 3 for cummins parts.
Drain your fuel tank I have seen floaters in there that will block off the supply and when it dies the suction is broken and it releases. But change all filters and check your lines and elbows blow them out with air
While your at the parts store getting new filters & a lift pump.. pick up a can or 3 of brake kleen.. & spray that area down..
My first step was to replace filters. The next suspect thing was the primer level on the mechanical fuel pump, it just spun on the shaft so I took it off and fixed it, but I kind of think maybe the pump's just old and tired. I have to pull it off and find a part number somewhere so I can get a new one. I don't know why the filters are on the output side of the mechanical pump, you'd sort of think the fuel would be filtered before the pump? Anyway, that's how this is set up. When it died on the side of the road, I opened up the supply line to the mechanical pump and diesel ran out, so I'm thinking the fuel tank/line must not be blocked. If I bled the injector and got the air out, it'd probably run, but something is introducing air into the injector pump, then it quits. Oh, and after I took that picture, I cleaned up the whole area so it's not so nasty.
The lift pumps sux.. & they're only like 40.00, I think. Glad u cleaned the area..
