New Holland Repair

[murphysmom]

My New Holland TC35D is having issues. While running, it loses power & stalls. It feels like it isn't getting enough fuel. I pulled off the fuel tank, drained it & cleaned it. I also replaced the fuel line.

While checking it over, I noticed a wire hanging down & have no clue where it is supposed to be attached to. Any diagram to find out where this wire is supposed to be?

More description needed.

Hanging down from where....inside fender ? (check lights on fender to see if they work) someplace else ?

Did you solve the fuel issue ?

green wire by white clip right by the fuel filter. The tractor won't start now.

I found where it went. It was to be attached to the selinoid. But it still isn't running like it's getting enough fuel.

When you removed the tank and fuel line, did you also replace the fuel filter? If you got a bad load of fuel it can clog up a filter in no time. After all of that did you bleed the lines of all the air from tank to injectors? If it has a clean tank and lines, a fresh filter and you can get it to start I'd get it running, and crack the injectors one at a time and make sure they're bled properly. If after all of that it still won't run properly I'd be looking at the fuel lift pump. Many modern tractors use an old-fashioned fuel pump style that's prone to failure periodically....not sure what your TD35D has on it though. Follow the lines from the filter to the injector pump and if there's a fuel pump, snap a picture of it for us.

Did you bleed the air off after having the lines/etc open ? Sometimes you need to turn the bleed screw on the injector pump, allow fuel to flow a bit (you'll see little air bubbles IF you have air in the system), then tighten the screw back down.

If that isn't it, make SURE you're getting a good flow of fuel from the tank to the filter inlet. Unless you completely removed the tank, turned it upside down and flushed it, you can have a small obstruction (has happened TWICE to me, both time it involved insects in the tank) that floats around in the tank, then floats over the fuel outlet point, blocking enough flow to starve the tractor for fuel.

With the tractor sitting level, let it run until you hear it start to die. First, if you have a clear fuel bowl with a little pre-filter, IS THE BOWL FULL OF FUEL ?? If you can see any air space in it with the tractor trying to run, you DO have some obstruction between that bowl and the tank.

The last time it happened to me, I used a Rigid brand inspection camera (Home Depot) to look right in the tank at the outlet point, and there lay a dead wasp right over the 1/4" outlet hole. I took a long set of 'finger-grabber' things, reached in while using the camera, and pulled the dead critter out.

Problem solved.

Just used this thread to clear my fuel tank of Yellow jackets. There were about 5 of them in the tank and one had slid down into the fuel inlet. I had to use pressurized air on the outlet side of the valve to blow him back into the tank. Before that they there was only a trickle of fuel coming out. Then just used a kerosene suction device to suck all the rest of them out. Ran good for an hour afterwards without issue.

Thanks for the tip! I was thinking Injector pump getting weak and instead it was simpler by far and cheaper. I did change the oil in the pump while I was at it and cleaned the filter (it's a simple uncased type of filter on the Ford 1900)
