does any one know of a mechanic in the New York tri state area that works on Jimna tractors?
I had corrected the situation where the location of the valve under the banjo was located. With it in the wrong location I was getting no fuel to the injector pump at all. But this is corrected now.
At the present time with the fuel lines disconnected at the injectors I get little spurts of fuel at the injectors lines when I crank the engine. So I am getting fuel as far up to the injectors With the fuel lines connect to the injector the engine will not start. So, I am thinking maybe its the injectors themselves.
What else might it be? Can I flood the injector with fuel and try to start the engine without damaging anything?
finally got the bango fittings, but the tractor will not start. i see little spirts of fuel at the injectors when i crank the engine. does anyone have any suggestions. should i flood the injectors with fuel to see if that would do it. or clean the injectors or get new ones? or maybe this isn't even the problem. i have no clue anymore and its @#$% monday and i have no tractor… 🙂
Tommy, First, thanks for some of your other comments. I think, if i haven't already you save me from major damage to the engine.
Now, I would think when I pull the valve cover off I can see clearly how the 4-stroke engine is working and exactly when #1 cyclinder is finnished and then turn the fly wheel 180 degree from there to find TDC.
I see that the gear for the fuel pump turns 1 time for everytime the flywheel turns 2 times. So I changed the gearing on the fuel pump like you mention above, and have corrected the fuel timing problem.
Although I broke one of the fuel return banjo bolts on top of the injector, so I will have to wait a few more days to see if the engine will trun over for me.
Thanks again for your help and I will be ordering parts from you again in the future. from ed
one more thing. the fuel injector pump timing on the tractor right now has the fuel being delevered after the intake opens and when the valve starts to close

I loosened the bolts on the fuel injectors and now I can rotate the engine. thank you thank you thank you.
I adjusted the valve clearances with no problem.
Now for the injector pump and spill timing. I see fuel coming out of the number one valve and the angle from TDC is off by 50 degree's. the book says it should be around 20 degrees. I loosened the three nuts and rotated the injector pump both ways and still I get about 50 degrees difference in both direction. I don't see a difference rotating the injector pump.
any suggestion to get it closer to 20 degrees?
or what am i doing wrong?

Tractor never had glow plugs or heater. I don't know why? she always started fine for me. I have a handle on the right hand side which I use to start the engine which I call the compression release handle. i would hold this handle for a few second while turning the key and then when I release it the engine would start.
I did no see sludge anywhere but I thought something effected the fuel injector pump. Before I replaced the complete pump/governor assembly I was not getting fuel at the injectors. I purged the air out of the lines. Now that I have the new pump/governor I am getting fuel at the injectors. But tractor will not start.
I will look around for older post for spill timing.
I do have all the manuals for the tractor.
Your telling me if the compression release is held I should be able to rotate the engine. I will try this and if this doesn't work I will try to remove the injectors.
Thank you for the advice. Ed
