    Case 580B weak in foward and reverse

    I replaced a side window with 1/8" Lexan, which worked OK, but 1/4 would be much better for the rear window. I wouldn't use Plexiglas - it shatters into sharp pieces if you hit it hard enough. Polycarbonate (Lexan, Tuffak, etc.) is a lot tougher, although it's a bit more flexible. You can...

    580B sluggish transmission fix

    Hey Matt - welcome to the forum! Just in case you haven't figured it out already, this is the perfect place to get the help you need to fix your machine. There are a lot of possible reasons why a shuttle would stop working. Actually, it's probably good that it was working and then wouldn't...

    580ck wiring diagram with Alternator

    If you do decide to stay with the alt that requires a resistor, don't try to wire around that resistor - that's the way my '74 580B was when I got it, and why it wasn't charging - that sense wire provides just enough power to the field coil to get it going, after which it's self-powered (through...

    Case 580 How old am I? What am I?

    If you don't mind waiting for UPS, the best place I've found for filters is Action Auto Supply in Norwalk, Ohio. They have auctions on eBay and specialize in Wix filters, which I think are pretty decent quality. I sent them a list of the filters I needed for my 580B and they put together an...

    Case 580 How old am I? What am I?

    You asked "Is this a 580B, 580CK, or a 580BCK? Or "D" all of the above?" and the answer is, you have a 580B tractor. The CK stands for Construction King, which I always assumed meant that it had the loader/backhoe option. When looking for parts, 580B should be sufficient. If you're looking...

    580ck Torque converter with water

    I don't think you can afford to put it in the hydraulic system - the best Dexron price I've seen was Valvoline (at NAPA) on sale for about $3 a quart. I tried the regular univ tractor fluid after rebuilding the shuttle, then switched to Dexron when I ran into the cold movement problems. I also...

    580ck Torque converter with water

    When you change the oil, Dexron is a suitable replacement for the "universal tractor transmission" fluid. I've found that Dexron works much better at low temps - I used to have to wait for the fluid to warm up before my 580B would move - now it's ready to go right away. Of course, you always...

    580 B CK Dash rebuild/rewiring project.....

    Oh, one other thing - two of those "extra" holes in the panel are for lights. If your new gauges have lights, then you're all set. If not, replacing them with originals is very expensive. I just got some panel indicators with round plastic covers that would fit through the holes, then used a...

    580 B CK Dash rebuild/rewiring project.....

    Hey Okney1lz, nice work on the panel - the powder coating is a great touch. I started a thread a few months ago when I rebuilt my panel, in case anyone is interested in rebuilding the original gauges - not the easiest fix, but probably the cheapest way to do the job...

    580B sluggish transmission fix

    Hey tloft - thanks for the nice words, but putting me in the same category with Phil is a mistake - when vintage tractor repair finally becomes an Olympic sport (as we all know it should be), he'll be on the podium! :thumbsup PG

    How to lock the boom, 580B

    Is there such a cushion on the 580B? I can't find it on the parts diagram.

    580B sluggish transmission fix

    Update on the pressure question - I took out the converter pressure regulator and found that the spring had relaxed a bit. After stretching it out and compressing it back to the correct length (this gets rid of the residual tensile stresses), my converter pressure went from 26 to 33 psi, which...

    How to lock the boom, 580B

    I'm also just learning how to do this, and I've found that it's easier to do if you tilt the tractor forward, either by parking downhill or by picking up the back end with the outriggers. I'm hoping that after some practice I won't have to do this anymore! PG

    580-B .. Plowed yesterday .. Won't start today

    Yes, the clicking is the sound of the solenoid contacts snapping together, which you normally don't hear, not because they don't make noise, but because the sound of the motor cranking the engine is louder. If you hear the click, then either the motor isn't getting power or it has a bad...

    580-B .. Plowed yesterday .. Won't start today

    Sounds like a problem with the starter motor itself - if the battery voltage drops when the solenoid clicks, it likely means that the solenoid has made a good connection between the battery and the motor. Shorting across the solenoid (with no results) confirms this. If the motor is connected...

    580B sluggish transmission fix

    I don't think it's weakness in the engine or it would bog - the engine speed doesn't change as the tractor slows down. Old doesn't necessarily = poor performance. If a machine is maintained to factory specs, it should run like new. Change the oil and drive it forever - that's :my2c

    580B sluggish transmission fix

    I'm thinking the problem is in the torque converter - I'll bet the fluid needs to be warm so that it thins out enough to flow properly between the turbine vanes. The thicker fluid might just get "sliced off" by the blades (since fluids can't resist shear stress), rather than being "flung" from...

    580B sluggish transmission fix

    Like many others, I've been a bit disappointed by the sluggish behavior of my 580B shuttle transmission in cold weather. It works fine when it's warm, but takes a good 5-10 minutes of warm up before it will move properly when the temp is below 30 F. I've had the shuttle, pump, and control...

    Rebuilding the 580B instrument gauges

    So, the rebuilding of the panel continues. I've got all the gauges working and mounted, and I'm getting the wiring sorted out. Just got the alternator alternating this morning. Previous owner had the great idea of jumpering the 75 ohm resistor to increase the alternator output, which of...

    Rebuilding the 580B instrument gauges

    Ah, OK, now we can see the problem - your sensor is completely disintegrated! I wish I could tell you that it's rebuildable, but unfortunately, there isn't anything left to rebuild. Three suggestions: Have you tried aftermarket parts suppliers? Tractor Stuff is my favorite - they not only...
