I have a new project a 1965 Ford 4000 3 cyl diesel and I have never worked on a diesel before This tractor has been sitting for about six years and my problem is no fuel to the injectors. I have replaced the filters bled the filters and the injector pump but still on fuel to the injectors. this tractor has a CVA pump
I am getting fuel thru the leak off line back to the tank. I know these pumps have to be timed so I don"t want to remove the pump unless it is necessary What do I do now
Thanks
 
I believe if I had fuel that far along I would loosen the injector lines and either crank it over or pull it with it in high gear till you can see fuel comming out of the lines without air bubbles. Then tighten the lines and pull it and start it. Sometimes it's pretty darned hard to get the air bled out of them. Just my thoughts, Keith
 
I have tried that and even took the line off the pump and pull it for about three hundred yards still no fuel
 
If it has not run in awhile I'll bet the plungers, and/or metering valve is stuck from old stale fuel, and a complete teardown and cleaning will save the injection pump. Timing is simple on this one, a scribe line on one flange, and 3 bolts through the pump drive gear, and a dowel in the gear that locates in the drive hub. Can't get it out of time unless gears are removed.
 
I have about decided the pump will need to be removed, now does the timing cover have to be removed to take the gear off or only the three bolts that ataches the pump to the motor
Thanks
 
The timing cover in front of the pump drive gear must come off to get the three bolts out of the gear. Leave the gear in place, remove the pump hardware and remove the pump. Then you will see the gear pin that aligns with the drive hub slot. As long as the gear is left in place all will go back in time.
 
Thanks so much for your advice I think I can handle that. I am sure it is just stopped up with old fuel. It was running fine at the time my uncle passed away and has just been sitting ever since. I was hoping it could be cleaned out with solvent or air without removing the pump. Is there a way the pump could be filled with solvent, WD 40 etc. let set over night then flushed with fuel or am I just waisting my time I also don't want to do anything that will damage the O-Rings or other parts I have checked around and have found a guy that rebuilds these pumps so I will remove it and take it to him
Thanks Again for your help
