784 hydraulic issues

drakeffa1086 · Sep 6, 2019

Hey guys I have a international 784 diesel tractor with a front loader it is having hydraulic problems. Ive done some hydraulic testing. I have flow rated the pump at the aux valves I only have barely 10 gpm @ 2000 rpm ive read in the service manual that you should have 12 gpm this kinda tells me that I have a hydraulic pump issue, Old tractor equals gear pump, while operating loader at a idle it will not move you have to give it a little fuel to be able to run the loader. I also plumbed a gauge into the aux valves and at high idle i do get 2000 psi, but while flow rating it wont even break 1700 psi

I have been leaning towards a hydraulic pump but wanted to get more advice thank you in advacne

I may be way off here but when was the hydraulic filter last changed , screen and filter could be clogged up a bit.
