Ford 4000- Can you help?

I have a 1968 Ford Diesel 4000. It does not have a self priming fuel pump(injector). I can not figure out how to bleed the air from the pump and get it primed. If you can tell me how to prime the pump and bleed the lines, please respond to this message or e-mail me. If you leave a phone number I will call you. If you can help, please do. It was my grand fathers tractor and my grand mother wants to see it run again and I don't have very much experience with tractors. Thanks.!

I see several posts from you on different boards, and no one has bothered to tell you the bleed screw on your injection pump is just above the horizontal centerline of the pump body about 2/3 of the way back from the front. It will take a 5/16" wrench. After bleeding the filter, remove this plug, Crank the engine with the fuel shutoff cable in run position. You may get fuel & air, but crank till clear fuel spurts to or beyond the front tire. Then bleed the injectors as others have instructed. Done properly, no ether or other exotic motor diets are needed. I am assuming your 4000 has the rotary CAV injection pump.

Thank you very much for getting back to me with my problem. It is nice to have someone take the time to help me. I don't know much about tractors but my granny really wants to see that old tractor runnin' again. Is it possible that the plug you refer to could be plastic because there is one on it or is the 5/16 wrench nut you are talking about something different? I hope to hear more help from you soon, thanks!!!!!

The bleed screw on the pump I am referring to is a steel bolt-like fitting with a 5/16 hex head. It is found as I described, but only on the CAV rotary injection pump. My dilemma is that I don't know for certain that you have this particular pump on your tractor. This pump is cylindrical in shape, oriented horizontally with the injector lines coming out of the rear quarter, spaced equally around the circumference of the pump body. The throttle and shutoff linkages enter a rectangular housing sitting on the top of the pump. If your injection pump has the linkages entering the side, and the injector lines exiting the top in a row, let me know, and we will discuss bleeding THAT pump. Just to be sure you have the age correct, this is a 3 cylinder tractor, isn't it?

I am certain that there are other ways than what I am going to suggest. However, here is what I would do. Charge the battery and have a good charger on hand. Have a can of starter fluid available. Turn off fuel and remove the old filter(s) and fill the replacement new ones with clean fuel and install them with the fuel turned on and spilling. Clean up all spilled fuel. Loosen only the fuel line connections to the injectors at the injectors. Move(pull) the fuel lines to verify that they are loose ( a small movement is O K) from the injectors. Pull down on the throttle control. Remove the inlet air filter. Crank the engine over with the starter and observe for fuel spewing from the loose connections at the injectors. Caution, Do not crank excessively to overheat the starter. Once you see fuel leaking at the injectors stop cranking and promptly tighten the loosened fittings. Set the throttle for a little more than idle, put the charger on the battery, get the starter fluid in hand, start cranking the engine and then and only then spray a little starting fluid into the breather canister. When the engine hits if it does not want to run on its own spray a little starter fluid again and continue this until it is running on its own. It may be running rough but will clean itself up after a few minutes. Happy tractoring!

Sounds like a very good way to bust something sir. You might be judicious in using ether, but most people are not. I sincerely hope this guy doesn't come away with at least a bent rod from this experience! Probably at minimum he'll come away with a busted starter drive!

Bern, I do not like using ether but it is a fact that people do use the stuff. Many diesel engines come equipped from the factory with the means to apply ether to the engine. Please enlighten me as to how you would use the product. The man has a problem and he needs to get the engine going.

I do have a problem and I would like some more help. You aguys have been extremely nice in responding to my message and I really appreciate it. The injector pump has a plug on the side of it and I am not sure how to tell if it is primed or not. I heard that diesel should be pouring out of it when it is primed and the engine does not even have to be turning. I just can't figure out how to prime the pump. Once that far i can bleed the injectors. Any more advice on priming the pump, guys? Thanks...

One of the above posts identifies the location of the plug on your specific tractor. I did not know where it was located. You will have to remove the plug and turn the engine with the starter. Once you get a continuous flow at the injector pump replace the plug and follow the procedure I posted earlier. You will get the tractor to run by following the instructions. Obviously the other men were apprehensive about using ether but most of the horror stories are old wives tales. If you do not feel comfortable with the ether then delete that portion. I do not suffer from the anxiety and as a matter of fact just today I started a Cat 955 asssisted with Devil's pee (ether) that the neighbor let run out of fuel. Using good judgement and using the ether sparingly is the key. It can save a lot of aggravation and agonizing over discharged batteries and overheated starters.
