    Brakes Being Applied Without Pressing Pedal

    alrman: My memory thinks it is normal hydraulic oil in the brake fluid reservoir, and that is what I used. I need to check the book to verify. The road was bumpy and the heavy rear end caused the machine to lope which required a slower speed. The pedal springs are good. Each time this...

    Brakes Being Applied Without Pressing Pedal

    1990 Case 580K Backhoe. The brake fluid level was low and I added more oil to the mark. When I started driving in 4th gear, I noticed it slowing as if I were going uphill. I stopped and pressed the brake pedal. It no free play and no leak down. I pressed it several times and it then had some...

    CASE 580K BACKHOE ELECTRICAL

    PROBLEM FIXED!! 1990 Case 580K Backhoe that would not start. After proving the Neutral Start Switch was OK, and then while checking Key Switch to Starter Relay wire 21A, I could not find the Pin C of Connector C which should have been the only break. So, I ran a parallel wire from the Key to...

    CASE 580K BACKHOE ELECTRICAL

    alrman: It is 32 years old, with a few flaws. I am 87 years old with more flaws. A new wire is the answer unless some wizard comes along with a better idea. Or, someone else comes along and says "Step back and I will fix it". Thanks

    CASE 580K BACKHOE ELECTRICAL

    Final Problem (maybe): Wire 21A (white-red) leaves Key Switch and then disappears into a sheath heading downward in the side console and then it is broken somewhere along the way to the Starter Relay. In between the Key Switch and the Start Relay, there is a "PIN C OF CONNECTOR C" shown on the...

    CASE 580K BACKHOE ELECTRICAL

    Thanks alrman!! I found the Starter Relay earlier. The Return To Dig Relay is side by side closer to the front of the machine. Now I need to look for the Neutral Start Relay where you suggest. Then the fun begins, tracking the electrical path. This will take some time for the 87 year old...

    Where is the CAB RELAY

    Thanks sheepfoot again. I found the relay. Both + & - wires to the relay solenoid were corroded. After cleaning them, I heard the solenoid "click". Now the work and flashing lights work like they should. I really appreciate forums like this. I live out in the "boonies" and it would cost a...

    Where is the CAB RELAY

    Thanks sheepfoot. Open cab with ROPS so there is a roof, but no windshield or side panels. None of the lights are working. Just beginning to trouble shoot. There was a corroded loose wire on the ignition switch that kept it from starting a couple of weeks ago. I fixed that with a new...

    Help removing steering valve on 580k backhoe

    It is partially under control. I loosened the steering rod tube enough to slide everything down so I could see better. All of the bolts were removed earlier and there were no pins to remove. The tube flange and the top of the valve were just "stuck" together. I had a "long" cold chisel and...

    1991 580K Case Backhoe, 2 wheel drive, non tilt-telescope steering wheel, no horn. The steering valve is leaking. The Case manual says to remove the 5 hydraulic hoses, but it is so tight, I wanted to disconnect the steering shaft from the valve...drop the valve down a little and then remove...

    Steering control valve leak

    1991 580K Case backhoe. I have not removed the valve yet, but it appears to be leaking from the top side seal. The repair book says I "may need" a CAS-1239 Centering Spring Tool. The book also says it is available from Service Tools, P.O. Box 314, Owatonna, MN 55060. I Googled the CAS-1239...

    Case 580K backhoe BRAKES

    fpgm04 "lay on your stomach" I know what this means. I had knee replacement surgery a few months ago and the surgeon I could do most any thing except "kneel" on that knee. I used to do a lot of jobs on my knees, so this has been a pain in the a$$. So, when I was replacing the flex brake lines...

    Case 580K backhoe BRAKES

    caver, I never could find the bleed valves. I recently started loosing brake fluid. I finally had to remove the seat and the big plate under the seat. One of the flexible brake lines was leaking. Since it was quite a job to get to this flex line, I replaced both of them (about $60 apiece if...

    Case 580K backhoe BRAKES

    CaseCI: Thanks for the clue. Every little bit helps. I had hernia surgery, so I will not be doing any heavy lifting for a little longer. I don't use this backhoe very often, so I may not get to it before Spring. But, it is still on my work list. Keep the information coming if you find out...

    Case 580K backhoe BRAKES

    1991 580K Backhoe. When I first start up, everything works fine. After 5 or 10 minutes, the tractor ground speed starts to slow down. I discover very little pre travel on the brake pedal, so I know the brakes are dragging. If I stop and work the pedal up and down a few times, the pedal now...
