    580B shuttle oil change

    This is my first time to drain the shuttle. I drained my shuttle oil and about 3 gallons came out. Surprising to me it was still a bit golden and looked good with no water. I peeked in to remove the allen screw at the torque converter and there is a threaded casting inside the hole that had...

    poor man's spool valve repair

    I printed that page from the Case catalog. Which cylinder is the relief valve assembly in section 178? There are 3 on the bottom and two on the top. I cannot tell from the diagram. Thanks, David

    poor man's spool valve repair

    Hey, you guys are great. Replacing the o rings on the relief valve assembly may be a doable task for me. John Deere didn't open the spool assembly. They charged me for diagnostic time to eliminate the the cylinders. I was pretty sure of that before I took it in because they were all repacked...

    poor man's spool valve repair

    This is the model 35 loader, sections 174 of the case online parts diagrams. I tried to upload a picture of the valve but couldn't get the attachment to be accepted. Don't know how to resize. I don't know if I need to replace the guts to the relief valve or the clam/tilt valve. The manual...

    poor man's spool valve repair

    Two. You have me concerned. What is the expected pressure on those lines? Is it greater than 1000psi?

    poor man's spool valve repair

    After spending $150 at the local John Deere dealer and them telling me they cannot repair my Case spool valve I came up with my own engineering. My bucket curl function would slowly creep down making using the forks for carrying pallets risky to say the least. I made several calls to...

    spool loader leak down

    Hi guys, It's been months since I've posted, but I'm back. My 1975 Case 580b has an annoying leakdown in the front bucket and digger bucket on the boom tower. I took it to John Deere (no case dealer around) to see if they could fix it, and they diagnosed leaking spool valve assemblies...

    parts catalog link 580B

    I finally gave up and just wired the brake lights directly, so now I have no turn signals. I can live without them. I still have road flashers and brake lights. David

    parts catalog link 580B

    I found my brake light problem. It's in the turn signal switch. I found the part number (D5208) and called Case for the switch. Wow, that little switch is $74. I'm trying to come up with a home brew, but it's a complicated circuit with a 12v hot for the brakes, and a 12v hot for the turns...

    parts catalog link 580B

    I know it's been posted somewhere, but my searches come up empty. What is the link to the Case parts diagram website? I had it and lost it. Many Google attempts have not gotten me back to the diagram site. I'm looking for a wiring diagram for a 1975 580b CK backhoe. I can't get my brake...

    digging bucket smooth blade

    I couldn't find a smooth blade for my digging bucket, so I just made one and bolted it on to the teeth. 3 minutes on and 3 minutes off when needed. I used it last week to find a sewer line in my yard. I hit the line, dented it but didn't bust it open because of the smooth end. 4 weeks ago I...

    580b makes a noise in 4th gear

    Thanks Phil, I hope it is the brakes, but it puzzles me that it never has done it in any other gear. When I have some time, I'll start tearing into it. I am about to use the machine a lot soon to prep a small parking lot for paving with concrete. I need the machine now, so I hope I don't...

    580b makes a noise in 4th gear

    When I travel in 4th gear, low range my tractor will roll just fine until I put on the brakes. Then it sometimes sounds like all hell is breaking loose inside the transaxle. The tractor shakes and grinds. Let off the brakes, it coasts fine. Sometimes it makes the same noise when starting off...
