I am having problems with my John Deere 950 tractor.
I was having problems with the tractor losing power and thought it may be the fuel filter. I changed the filter and bled the lines precisely in accordance with the operators manual.
The tractor will start and idle, but when operated it will lose power and the engine stops.
What I have done so far is:
1. Change the fuel filter.
2. With fuel turned on, I loosened both bleed screws above the fuel filter.
3. Loosened the bleed screw on the injector pump.
After the above, it would crank, but when operated would lose power and die.
So then I bled the injection lines.
1.Loosened all 3 lines at fuel injectors.
2. Loosened Number 1 and Number 3 delivery valve holders 1/4 turn.
3. Fuel was supposed to appear at Number 1 and 3 fuel injectors. This never happened unless I tried to crank it, then fuel would appear.
4. I tightened everything back up and tried to crank it.
5. The tractor runs but there is a steady stream of air bubbles visible in the fuel sediment bowl. It will idle, but will die when operated for a couple of minutes.
I thought it might be a bad seal with the rubber "O" ring around the fuel sediment bowl, so I ordered a new one. It hasn't arrived yet.
Does anyone have any ideas on what I am doing wrong. I hate to take this to a JD dealer, it will cost me a small fortune.
