tommyw-5088 Posted March 14 Share Posted March 14 4366 was running fine when i parked ,it sat a few months and now the injector pump wont put out fuel to the injectors . I tried to bleed it and no fuel coming out . do the barrels stick in those inline truck pumps ?,or is there somthing else thats serviceable on the tractor?

ThirdGenRed Posted March 14 Share Posted March 14 Make sure the electric fuel shut-off solenoid is turning on. We had a S1900 with a 466 that would not click on sometimes, we would spray wd-40 on it and it would be good for a while. Quote Link to comment Share on other sites More sharing options...
IHC_1470 Posted March 14 Share Posted March 14 Does it have electric shut off or is it a cable pull? Either way make sure the solenoid is working as mentioned or make sure the shut off is pushed in or the cable is not loose in the lever. Been more than once the truck would not start because I forgot to push the handle back in. Quote Link to comment Share on other sites More sharing options...

acem Posted March 15 Share Posted March 15 Im a little confused. 4366 and inline truck pump? It would be helpful to know exactly which pump you have. Apparently it's not the original AB100. Thx-Ace Quote Link to comment Share on other sites More sharing options...
IHC_1470 Posted March 15 Share Posted March 15 So how are you shutting it down then? Ace I believe he said it was an in line pump so I am guessing a Robert Bosch pump. Some pictures would be helpful. Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted March 15 Share Posted March 15 From reading the title and the post I am going to say that it is a 4366 which has a DT466 truck engine in it, complete with the inline injector pump from the truck. Weren't all the pre-94 inline truck pumps variations of the Robert Bosch pump? Quote Link to comment Share on other sites More sharing options...

Tad Wicks Posted March 16 Share Posted March 16 To answer your question, YES, the plungers will stick in the pumps thanks to low Sulfur fuel, I have a D4 Cat thal all the plungers stick after sitting awhile, fortunately with that pump, a side cover comes off and I can tap the cam followers back down to get them going. There is a definite need for some kind of lubrication in the fuel. I have had to do the same thing on a friends D5. Quote Link to comment Share on other sites More sharing options...
tommyw-5088 Posted March 17 Author Share Posted March 17 Thanks guys , im going to try to get some sea foam or penetrant oil in the pump . Was thinking of spraying some free all in holes after pulling injector lines . Anyone think this could be sucessful , Yes its a truck engine transplant complete with inline pump .

tommyw-5088 Posted March 17 Author Share Posted March 17 then what about putting some sea foam into pump via intake line from filters ? Any way to try to free it up on tractor ? Im not trying to work a thousnad acres with it , just want to disc some rough ground we cleared . No way i want the 7140 with almost new firestones in that ground .

acem Posted March 17 Share Posted March 17 I think there's a way to free up the fuel delivery while it's on the engine. I've never done it but I know people who have. What pump is it? A pic if nothing else. How's the truck pump work out on a tractor? Quote Link to comment Share on other sites More sharing options...

Tad Wicks Posted March 18 Share Posted March 18 It should be a Robert Bosch "P" type inline pump. This could prove to be a dilemma, you won't be able to pull the barrels easily because the pistons have to come out the bottom first and of course they are stuck, the pistons are at their apex, so way past port closure, so there is no way to get any kind of solvent into the pump barrels and the delivery valves can't be removed until the barrels are out. There are plugs on one side of the pump to lock the pumps up for camshaft removal but are no help. You might just have to get strong and pull the barrels, there is a puller for them, there doesn't seem to be an alternative other than pulling the pump. Remember one thing, when the engine shuts down, the governor goes wide open, so all the pumps are stuck at the top wide open throttle, so be sure to do them all, or make sure that the rack assembly is free. So if you do 3 or 4 and the rack can't move and it starts it will run away to destruction. On other type pumps I have filled a grease gun with a solvent or naphtha and made an adapter to screw on where the injection line goes and a grease gun can make all of 10,000 psi, some might get past the delivery valve, worth a try. This is all off the top of my head as I remember it, so I might be wrong. Tad Quote Link to comment Share on other sites More sharing options...
Injpumped Posted March 18 Share Posted March 18 So it would be an A pump or an MW on an international harvester built engine, the P pumps were not used until the new generation series came out. What I do is remove the inlet off side of pump, blow the fuel out with compressed air carefully, then try to fill fuel galley with brakleen, plug it when full. Bad part is it leans the wrong way. Taking the return out the back side may help. Take lines completely off outlets. Let sit with the brakleen. Check periodically as the brakleen will leak by inside and also evaporate a little. If this has a kill cable, it likely sat in the shutoff position. After sitting a while with brakleen still in it, try cranking it with lines left off. See if it spits the fuel out of each outlet. May run out of brakleen after a few seconds. Keep refilling it. Crank it some more. Move the shutoff lever and throttle levers to see if can feel the rack moving properly. If it keeps pumping good, connect the fuel supply line and returns back to normal. Crank it after bleeding the fuel galley again, observe foul now spitting out of the outlets. Before putting injection lines back on, make sure it quits pumping fuel when pulling the shutoff lever to kill position. Try it back and forth a few times to make sure it's got control. Never tighten the lines if it doesn't change pumping status. It will run away if you do. Only tighten lines after completely verifying the shut off does control it, showing the rack is moving properly. This is a last ditch effort, otherwise you'd need to remove the pump. No way would I ever suggest tearing it part way apart on the engine. Good luck and I hope if frees up for you, and remember to keep fresh fuel in it. 2 Quote Link to comment Share on other sites More sharing options...
CIHTECH Posted March 18 Share Posted March 18 2nd what is stated ^^^^ I have been able to get precious few free with this method, but even a blind hog finds an acorn once & awhile. "Been sitting" for ten years is better than sitting for ten months with today's fuel. 1 Quote Link to comment Share on other sites More sharing options...
Tad Wicks Posted March 18 Share Posted March 18 Good Morning INJPUMPED; Question, does this pump have a shut off valve in front of the pumps that gets closed or is there linkage that moves the rack to a no fuel position? The reason I ask, is, that if there is a stuck shut off, then the pumps might indeed be moving just nothing to pump. I believe that I might have a manual on that pump, just need to find it. Thanks Quote Link to comment Share on other sites More sharing options...
Injpumped Posted March 18 Share Posted March 18 Typically to shut the engine off the governor has a shut off lever that moves the rack to zero delivery. Sometimes it's controlled by a cable, other times it has a solenoid connected to it so it will shut off with the key. Those can be made cable easy enough too lol! Only time I've ever seen a shut off valve in the fuel line to pump is for a emergency safety system like for pulling, or a murphy system. There is 2 check valves in the transfer pump where the primer is located and they can stick shut, but you would not ever get it to prime at all.

tommyw-5088 Posted March 18 Author Share Posted March 18 thanks everyone , looks like i can get a real small funnel and fill it with brake clean via the intake hose . Quote Link to comment Share on other sites More sharing options...

"Been sitting" for ten years is better than sitting for ten months with today's fuel. That is very correct. Ten years ago had the old fuel in it that almost lasted forever and had lubricity in it. The new low sulfur stuff can stick a pump in a few months. Thank you very much feds for this crap? Quote Link to comment Share on other sites More sharing options...
Injpumped Posted March 19 Share Posted March 19 Brakeleen is an aerosol, so it just gets sprayed into the fuel galley. Not sure a funnel would be needed. Do not use brake fluid lmao! Quote Link to comment Share on other sites More sharing options...
