The diagnosis guides below start from the symptom, list the checks in the order a workshop should work through them, and say which parts usually solve it. Full index: diagnosis guides.
Boom, arm and cylinder functions
A function that moves smoothly at speed but stutters when the lever is barely open is fighting friction or air, not power.
Pump and pressure supply
Case drain flow shows how worn a pump or motor is without removing it.

In low ambient temperatures the oil is the problem, not the pump.
Oil, filtration and the system as a whole
In high ambient temperatures the hydraulic system runs near its thermal limits.
