hydraulic problem on Cat 330b excavator

jimechMember

Please assist with a diagnosis on this machine which I wish to acquire. I am a mechanic but I have very little knowledge of hydraulics. The following hydraulic responses are way too slow: bucket movement and the right hand side track movement. The slew/swing motor has no power. I am wondering if these functions are all fed from the same pump and it could just be a pump adjustment?? I know the pump was recently replaced with a cat dealer reman. unit. Please help ASAP.
