    Slow/Weak Hydraulics on '72 JD2030 Front End Loader

    Hoping I can get some direction on the likely problem.

    Front end loader wasn't fast moving when I got the tractor 6 months ago, but was quick enough. It had enough power to bring the front end off the ground easily. Discovered some water had gotten into the hydraulics from un-booted gear shift levers. Drained and put in new fluid. Still worked ok, but didn't improve the speed or power as I had hoped. Now all of a sudden loader moves like a snail and pretty much has no up or down power.

    No loss of speed or power in the rocker shafts, so seems to be isolated to the loader.

    Didn't make any adjustments or changes. Not low on fluid. No fluid leaking.

    Any suggestions would be greatly appreciated.

    Where are you located in Texas? If you haven't already checked/cleaned hyd sump screen(key 34) then you need to. Also check to be sure hyd filter relief valve(keys 28-31) is seating. What type valve controls FEL(ind or scv)? I'll also suggest to check/set hyd stand-by pressure at 2350 psi.

    Hi Jim,
    Thanks for the info.

    Though I have a fair amount of auto and small engine weekend warrior mechanic experience, I'm a tractor newbie.
    I don't know which type of valve controls I have, and I don't have tools to check the pressure.

    I live in Granbury, but the tractor is just north of Graford at my little ranch.

    I see you are just east of Cleburne, a couple of hours from Graford. I actually bought the tractor from Floyd Camp Tractor & Trailer Sales in Cleburne.

    Any chance I could hire you to come help me get this fixed?

    Sorry I'm disabled & can't travel that far. I know Floyd & he buys/sells lots of equipment. If you have mechanical skills you can more than likely repair problem with the help from members of this forum. Most important thing to do first is check sump screen & hyd filter relief valve. A 5000 psi gauge costs about $15 from Surplus Center. Ind valve should be mounted on loader frame or scv controlled will have hoses plugged into rear of tractor. You could post photo of levers that control loader then we'll know what controls FEL. Back in the 70's while employed at local JD dealer I picked up a new piece of equipment at the JD dealership in Graford.

    Understand Jim. Was worth a try.

    I have not checked/cleaned the sump screen. That will be my 1st step.
    If that doesn't do it I'll try the hyd filter relief valve. How aggressive can I be
    cleaning them? Carb cleaner followed by lubing with hyd oil ok?

    I had my 67 1020 get water in the tranny thru the cracked shifter boots. The first flush I changed the tranny filter and did not know about the sump screen once I found out about it another flush and fill with filter and a new sump screen it worked wonders. I installed new shifter boots and it's been three seasons and still working fine. I got a new sump screen from Deere for around 15$. Good luck.

    I think you'll be fine spaying carb cleaner on screen but no real need that I remember to lube with oil. If the loader is controlled by a valve mounted on loader then it's possible valve could have a blown internal seal causing hyd to chatter.

    Thanks Tx Jim and DrifterBike.

    Planning to drain, install new filter and clean the sump screen this coming weekend. Will let you know how it turns out.
