JD455E track loader with back hoe 1987
My terminology may be wrong. I call parts what they seem to be to me.
tractor usually starts well but sometimes stalls especially if going up hill with out full throttle and then will not start. I eventually leaned that if I loosened a
cap at the end of the fuel return line, fuel will come out, it will start, and then I will tighten the cap back down and problem is solved. But this time when I
tighten the cap back down it looses power and eventually stalls again even at full throttle. The tank is full and the tractor is now fairly level with the front end
only slightly higher.
The cap I am talking about is at the front end of a common rail that extends back to the last cylinder and then back to the tank. Midway it also T's off and goes down
to the top of the injector pump. There are also 4 lines from the injector pump up to each cylinder.
Could the line back to the tank be clogged and cause this? Why does it go to the tank and back to the injector pump? Should I blow it out with compressed air back to
the tank? Do I need to bleed some other line like the one that goes back to the injector pump?
Thanks
Dave
