Hey guys, I’ve got a farmpro 2420. I started having overflow out of my vent tube. (Problem)lol
Please read below before rushing to give advice. Likely already checked the basics.
Well after inspecting, it appears I have air feeding into the system. Let me explain.
On this tractor there is only a hard line going front the reservoir/filter to the hydraulic gear pump.
From there it goes to a diverter valve, then the steering, to the back lift.
I’ve checked thoroughly. No gunk no obstruction to cause cavitation in the sump. Not a loose filter assembly. Not a hole in the hard line. Nada! Got it back to the pump and all lines are tight and no sign of leaks or loose fitting.
This just spontaneously started. The only thing I feel I noticed is when it happened my hydraulics slowed down.
Watching through the fill port I can see minor fizz when I first crank it. After it runs a while it gets so agitated it boils out. It appears that using the lift slows or calms the agitation.
No the fluid level isn’t low causing the foaming. No it isn’t high or overfilled. I’ve checked cold and when it begins to run. No possible way to check when hot unless I drain it dangerously low. Yet again it’s not a true reading because of the foaming. The lift still works but has minor signs of the air in the system. Like a slight jerk when first engaged. Perceived minor slowness in lift speed.
To my understanding on the outlet or output side it would simply manifest as a drip “leak” due to the pressure pushing the fluid “out”. On the suction or inlet side it can suck air “into” the system! Thus the foaming produced through the system.
Other than the gear pump itself somehow sucking enough air. THATS A LOT OF AIR.
Any ideas, seasoned wisdom or tricks to pinpoint this problem???
