The original subject was Case CX100 power problems.

Hi there. im new to the forums but im in need of some advice

We have a 2000 (i think) CaseIH CX100 with the 16speed and fwa. 2060 hrs.
It has the Perkins 1004.40T diesel in it. But it has no power. when you bring the machine under load it is as though there are no governors and the engine just begins loosing rpm. no effort, no smoke. The boost diaphragm was ruptured, but it has been replaced and pressure is felt coming out of the air line from the turbo at the boost diaphragm. No improvement, possibly worse. Turbo was examined, turbine is tight and pushes enough boost to visibly see the wastegate mechanism move a little when revved up. Both fuel filters have been replaced, lift pump seems in proper condition and fuel lines and delivery all seem clear. We inspected the shutoff solenoid and it seems like it is correct. as said, there is never any black smoke. It almost seems like the issue is in the injector pump, but the tractor starts and runs well. Has anyone else had this issue? I wanna try everything i can before we have to buy a $2000 injector pump. Its a Lucas pump, if that helps. thanks for any help y'all can give.

my reply - Hi. did you find a solution to the problem?
We have the exact same isue with our cx100 4500 hours.
 
Probably no point in responding this long after you asked but in case someone reads this in the future. . . it was a combo of a bad injector and bad injection pump. The Lucas (Delphi built) injection pump is apparently a lousy pump. Mechanics all say to put a little cheapo gas motor oil (SAE30 or the like) in the fuel to increase fuel lubricity, because those pumps don't tolerate the lack of lubricity in modern diesel fuel.
