Hello all, I could use some help. I bought a Bobcat 753H a couple months with a problem and I cannot figure it out and I was hoping you guys could point me in the right direction. I bought my bobcat knowing the lift and bucket hydraulic was weak and got worse as the machine warmed up. Without testing a thing I assumed it was the pump so I replaced it and the filters and added new oil. It didn't change a thing. So I then made myself a pressure gauge and hooked it up to one of the aux lines. It shows about 1200 psi idling and almost 2000 psi full throttle and this is when the machine is cold. Could the pressure relief valve on the spool be causing this? Any help would be greatly appreciate!
