CaseIh JX 80 running rough

Bama Ray · Sep 10, 2012

I have a 2007 CaseIH JX 80 it will run rough then smooth out and run fine ..it may run a couple of hours fine or it may only run 10 mins...I have drained and flushed fuel tank refilled with filtered fresh fuel...new fuel filters, clean screen on fuel pump. When it is running rough you can shut it down and remove filters drain them and reinstall and prime with hand pump then it runs fine for hours or min. you never can tell...when running rought rpm will go down from 2100 to 1900 up and down...it will do it when under a pto load like disc mower or baler or just sitting with no load...has 800 hours on it and just started this

would take a sample of fuel and let it rest looking for contaminants or water.

sounds like injector issue if all fuel sources check out.

My experience with New Hollands when that happens is the mechanical lift pump. Hard starting after setting over night also.
