IT14G loss of power

[gmyoung]

i have a 2000 IT14G PIN 1WN01351 that has limited power both in operating and speed. the engine is working great.....good fuel delivery, new turbo installed last week, all new filters(air, hydraulic and fuel). my next check will be to measure the hydraulic pressure output of the pump. does anyone know the operating pressures of the system that i should be seeing? And if anyone has any recommendations as to checking the pressures or other conditions that could be causing the power loss it would be much appreciated.

thanks

On top of hydraulic tank near the filler neck you have a ball valve, shut that off and see if it improves, if it does you have a stuck inching valve.

we tried that based on another thread on this forum i was reading but unfortunately it never helped my machine.

my next check will be to measure the hydraulic pressure output of the pump.

which pump? Implement or hydrostat?
Two different pumps.
Only thing that can affect power in both systems simultaneously is the engine. However pilot supply for implement control might come from hydrostatic charge- would have to look that up.

Are the hydraulics overheating at all?
