John Deere 4020 Hydraulic Pump Noise at Dawn Sanchez blog

John Deere 4020 Hydraulic Pump Noise. When the tractor hydraulics are consuming hydraulic power (flow and pressure) the pump crankcase pressure is low enough to. Outside of the loose bearings (which adjusted up just fine) & leaky seal, didn't find anything wrong with the pump but it still makes lots of noise. Pump appears to have been replaced at some point. My '68 4020 has a noisy hydraulic pump. But, obvioulsy, a very low psi reading indicates either a massive leak somewhere, or. If there is flow, even 1 psi will work fine. Recent purchase with no history. A 4020 may have more than one pressure regulator valve governing seperate parts of the hydraulic system. Your problem may be caused by foreign material in the pump stroke control valve & the screen in the stroke control valve housing. I bought a jd 4020 syncrorange tractor with a loader (aux connection, not from remotes).
