I am frustrated with my loader and need advice - Loaders
It seems possible that the entire loader is weak but the dump circuit is still strong enough to lift the front. I'm not sure how the pressure test was done. If it was hooking a gauge into the high-pressure line with a t-fitting then there would be little pressure unless either the loader or 3ph were used under heavy loads.

US3720221A - High pressure implement hydraulic circuit
A relatively low pressure hydraulic control system for a high pressure work output system in which a control valve is selectively actuated to position a variable displacement axial piston pump to control the flow in the work output system and to position a directional valve which controls the direction of work output. In such a system wherein two work outputs are provided, thereby …

May 01, 2006 · Therefore, the #1 remote circuit was supposed to have the "most important" function hooked to it, whether it was a motor or any other implement circuit hooked to it. Unfortunately, all the confusion surrounding the "priority valve" has made it a nemisis to many a farmer, mostly due to misunderstanding how the system works.

Jan 29, 2020 · That is usually a leak in the high pressure side of the system that causes the charge pressure to drop. The design of those pumps is funky to me. I had a 299 that lost a swash plate slipper in the second hydro pump, and because the design was to have a common suction port with the pilot (gear) pump, the gear pump sucked in the brass and trashed

Belly pump pressure - Farmall & International Harvester
Oct 31, 2021 · That is a open center valve. With valve handle in center you should be able to leave the pump engaged and have little to no pressure because the oil just makes a circuit through valve and back to reservoir. Cold oil may flow slow enough to show some pressure. Think the 600 PSI is probably what you have. Trouble is where you have the gage.
