Hi all,
I just signed up to this site this evening in hopes of getting some ideas on what I have to do to get my neighbors tractor running. It's a Japanese made "Forte" Yanmar 3 cylinder (series 3T) tractor. I'm guessing it's about 10 years old and has 560 hours on the clock.
A little history on what I'm dealing with....3 years ago the owner runs the tractor out of fuel. He attempts to get it re-fired, gets aggravated when he can't get it going, and leaves it parked in the barn for 3 years. He then takes it to a friend with some diesel experience who tinkers with it, and the guy ends up passing away from a heart-attack. I've now got the tractor and have no idea what was or wasn't messed with by the other guy.
What I've done so far in my attempt to get this running....
1)Replaced all of the the fuel lines on the engine. The old ones were dry rotted and cracking.
2)Replaced the fuel bowl gasket that was leaking.
3)Removed and cleaned the 3 valves from atop the injector pump. All 3 of the valves and components looked perfect, and showed no signs of being gummed up. The springs were not broken and looked like new.
4)Bled everything out. I really made sure there was no air in the system.
5)Fuel tank is full with fresh diesel.
When I crank the engine with the compression release pulled, I get a little bit of fuel from each of the 3 injector pump valves with the lines remove, but it seems inconsistent. A little mist is how I would describe it. I'm not sure that it's pumping enough. Another thing I noted is that when I try and start it, and then remove the steel injector fuel line from the injectors, it is under pressure, and a little fuel sprays out as soon as I break it loose. Is that normal? I tried to pull the injectors tonight but they were frozen up. I hit them with some pb blaster and will let that soak until tomorrow when I will try again.
It will run for a second or 2 with a shot of starting fluid, but will make no attempt to run without it.
Lastly, one other thing I'm not sure is normal is that when I crank the engine with the return line off the the last injector in the series just before the IP, it pumps fuel like what would be normally going into the injector pump.
If you guys have any advice, it would be much appreciated.
Tia,
Dave
