Ford 3600 CAV injection pump

Yeah... thats a bummer if the injector pump is not 100% assembled correctly. If you can't get it back 100%, I'd get it serviced.
With complicated things, I learned to snap pictures, that way I know how things go back together correctly.

Looked at the pump again. Cranked the tractor a few times and I found a leak on one of the hard plastic hoses on top of the injector. I must have done this when I loosen it from the injector. Crank the tractor a few seconds and it will wet you fingers to rub it off and for sure not at the injector were it goes on. Could this be the problem? I will replace as soon as possible. It will be a cold day in _____ before I mess with one of these pumps again. The last time I worked on one of these pump I had a heck of a time also. I will pay somebody if I can find them.

if it was running good before you started and now cant get any fuel out of the injector lines it will be the kill lever the problem the other spring is for the govenor and that has nothing to do with the fuel getting to the injectors just the amount of fuel. make sure the pin on the kill rod is in the little slot on the kill lever inside the pump

Wonder what the hard plastic hoses are called that goes across the top of the injectors? Trying to look them up with no luck.

Yes, the tractor started easy and ran good. Just ran it approximately 8 hours one day last week putting on fertilizer at high rpms to spread the fertilizer good (that was when I noticed the fuel leak). I may take the kill lever out of it just to try and see if this is the problem and kill it in 8th gear by pooping the clutch if I can get it started.

the hoses that run from injector to injector or a leak off line for the injectors also a return to the tank they or 3/16 hose

Maybe when you put the top cover back on you didn't get the little slide back in correctly. It's pinched of misplaced.

That's a fuel return line. There isn not much fuel ressure on it. You can have these leaking and the tractor still will start. So that isn't it. Just another thing to fix.

As whodat says they can be easily replaced with 3/16" fuel line.
The little clamps are available from any good hardware store - in those rows of miscelaneous hardware boxes. They are inexpensive and look/work better than worm drive clamps.

yep.. don't worry about the leak off lines. they just dump fuel back to the tank anyway. what you need to do is make sure the fuel kil doesn't have the rack shut down and starved.

Went to the Ford/NH dealership and the head mechanic that has been there I know since the 70's told me in about 5 seconds what was wrong. He said he had done it several times and it is easy to do. Check the top of the throttle shaft on top of the cap were the spring goes on and you will think it is in place, but it want be. He said it want start back up until you have it in the slot. He said to back it up counterclockwise a little and it will fall right into the slot and then put the lock nut on. I got home and in about 15 minutes had it going. Thanks everybody for the help.
