971 Ford Diesel Row Crop Injection problem!

leo172519 · Apr 11, 2010

Hi, I am new to this board and thought you may have some experience with my tractor. I have a 1962 971 Ford Diesel Row Crop and I cannot seem to find the bleeder on the injection pump. I took it apart to paint the tractor. I just took of the fuel tank and did not take the injection pump apart. When I try to get it started, I cannot get fuel to my injection lines. I have bleed the fuel filter and I have fuel to the pump, which leaves me stuck trying to get fuel to the injection lines.

If anyone in this forum could help it would be greatly appreciated. I have a Roosa Master Fuel Inection Pump, with no diagrams. So finding the bleeder in almost impossible without ruining the whole pump.

Thanks in advanced!!

Leo, I have one of those. You will not find a bleeder on the pump. You have to crack the lines and crank. It takes a lot of cranking. I have been told that you can spray WD-40 in the air intake and that it will run on that. Keep in mind too that it does need to turn over fairly quickly to start. I ran mine out of fuel 2 years ago, I just left it and went and got another tractor to finish the job. The next day I came back with booster cables and it took about an hour. I found that I also had a loose ground. Tightening it made it crank faster.

Have you tried cracking the fuel lines at the injectors and cranking to get the fuel to them? Getting fuel to the injector pump will allow the pump to prime the lines but you need to open them at the injectors or it will take forever and run your battery down. Before you start the process make sure that your battery is well charged.

I have a 961 and I have had the pump for new cup seals three times. I loosen the lines at the injectors and crank until I have fuel coming out of all the lines. I tighten them back up and try to get it started. The first time it took a second battery charge and a jump start battery. The second time after I ran the battery down I had my son hook on and pull it until it started and stayed running. The third time after I had fuel to the injectors with the battery I had my son hook on and pull it. It actually took less time and not any more pulling than it did the second time.
If and when I need to pull the pump I'll do the same as the last time.

Roosamaster/Stanadyne pump is self-bleeding when all is right. So, it has no bleeder screw. But, as they get older and worn, it gets tougher to get the pump rid itself of air at slow cranking speed.

If the pump has been off, you can save a lot of wear and tear on the starter motor by priming it before installing. Easy to do with a hand-held oil squirt-can filled with diesel fuel.

When on the tractor, best you can do is - bleed at the inlet to the pump and make sure all air comes out. Then crack the injector lines loose at the injectors and crank until they dribble. Hooking an extra battery to it (in parallel) to increase cranking speed will make it bleed MUCH faster. If you can up cranking voltage even by one volt (9 to 10 volts), it will make a huge difference in cranking RPM and how fast that pump bleeds itself out.
