John Deere 4020 Hydraulic Pump Problems at Gabrielle Garrett blog

John Deere 4020 Hydraulic Pump Problems. i have just started working on it but the problem has been worked by a few people first. The tractor is a late model. this fall hooked it up to a shaver hyd postdriver and noticed when we raise hyd ram on driver hyd hose vibrates. The steering and brakes work good, but the remotes are very slow. my new 4020 has some hydraulic issues. the service information in my web page is a quick solution. i'll bet there's over a 90% chance you have pump or charge circuit problems, and the pump is not producing enough pressure. why not check the pressure potential of the pump by using a hyd gage and see if the relief is set right and. I did it to my '68 4020 and i have let it set. if the hyd pump shaft is turning when the engine crankshaft turns then i'd guess the hyd pump has a faulty stroke.
