not that i know of mike....Is the fluid aerated?
Hi, where is the vane pump located, I'm having the same issue with our 928h loader.the final result of this thread would be.....after I waited for cat to show up to take some pressure readings I already figured it out oldschool.......sthethascope the implement pump....a rattly noise I detected so I removed the pump assembly...disassembled for inspection...found the implement vane pump had several broken vanes on rotor.....called a contact I had at cat...he confirmed they had low hour failures on these pumps.......ordered a reman pump supposedly there updated.........reinstalled and problem solved.......they als o said they went went back to gear pumps on the larger loaders for durability............
