Case 580E just quit driving

Since the 580C died after the extendahoe rebuild, I grabbed the 580E to move some gravel. It was going fine, but then suddenly I have no drive in either forward or reverse in any gear. I was just attempting to back up a pile of rock on flat ground at an idle when it happened. It's like it's just stuck in neutral.

I checked the tranny fluid and it looks to be okay (well, the hoe wasn't running when I did this, so I should probably re-check), so I'm wondering if the shuttle is a different oil reservoir and it that's a place to look? I didn't really see any dipstick/filler that was obvious. I only have a book for the 580C.

The weird thing is that the shuttle lever really isn't centered in the notch, so you sorta had neutral below the notch and forward drive really in the notch. I'm wondering if the linkage just broke or something? The thing is it still feels like it's acting normally, like there's the normal resistance when trying to move it into forward or reverse. Where should I be looking next?

I think it's low on hydraulic fluid due to more leaking cylinders, but I can't see how that's related, are they somehow connected? On my 1150H, when the tranny is low is does stuff like this.

The dipstick is just above the starter, you need to check it with engine running at low idle. You need to see if driveshaft is turning when the shuttle is engaged in forward and reverse.

Yeah, I found the normal transmission dipstick by the starter, so is the transmission and shuttle one unit that has the same oil? It rained a lot last night, but it supposed to be clearing, then I can get a chance to get under there and look without laying in mud :/

The transaxle & shuttle oils are different.
If the shuttle oil level is OK & there is still no drive
  • Be sure none of the transmission cut out switches are stuck - disconnect the solenoid at the shuttle.
  • Be sure the transaxle 4 sp gearshift has not been bumped into neutral :rolleyes:

Will get back there and try to find the shuttle oil dipstick/fill hole.

I tried to mess with the 4x4 shift lever right under the right side of the seat, didn't seem to make a different. Seems like it should be something simple really, didn't hear and loud bangs, etc.

I'll try to get under there today and look at the driveshaft, yes it's a 4x4. I keep wondering if I bumped the 4x4 lever and somehow got it between gears somehow, though it didn't appear to be. I'll crawl under there and have someone move levers and such.

The reason I asked is because there is a coupler that is between the driveshaft and the input shaft for the transaxle, they are bad about stripping out and causing the problem you described. Of course I'd check the 4wd lever too.

The driveshaft doesn't turn.

I finished rebuilding the lift cylinders so they don't leak gallons of oil, then the thing ran fine for a couple hours, then just quit driving again on a flat road with no load in 3rd gear. Really weird. I had just been hauling heavy loads of gravel for hours and it ran great.

We checked and the shuttle is rocking back and forth on the outside of the transmission like it should and hitting the metal stops at the end of its range (though the linkage might be a little bit out adjustment.)

I added a little oil, as it was slightly low, like a pint or less.

So now we drug it back a few miles on the chain behind the truck (in neutral) to the shop to figure out what to do next.

The book says something about checking the pressures. Is there something else we should check? It's not leaking oil or making nasty sounds, just quit driving both forward and reverse in any gear. Maybe later it will mysteriously start working for no reason again, dunno.

Check your declutch switch in floor and loader control handle. Also check wire connections for declutch solenoid, and for broke wires.

Is that the little pedal to the left of the throttle a couple inches? Never used it, so no idea what it's supposed to do :)

There's a little button on top of the handle that runs the front bucket, is that one?

Yes on the loader handle button, I'll assume that pedal is also. Spray some WD 40 in those switches. My 580L recently did the same thing after setting several weeks for a rebuild of the extend cylinder. Just wouldn't move. Found it to be the Shuttle Time Delay relay in the fuse panel had failed. It unfortunately is not a standard relay on mine and cost $100. I did figure out how to bypass it with a small jumper wire until the new one came in.

There should be a button under the brake pedals that is the declutch switch, it's for shifting on the go from 2nd to 3rd to 4th gear while driving. You can down shift with it also but only from 4th to 3rd.

Since this my dad's backhoe I'm repairing for him, I had no idea what a declutcher is :) I just popped the shuttle into neutral while rolling and shifted if I needed to.

So the tiny button on the top of the front loader lever does the same thing as that little rocker pedal between the throttle and the brakes?

I noticed there's a wire wrapping around the shuttle cylinder thing that rocks back and forth on the left side of the transmission that switches forward/reverse (or should), but I had no idea where that wire went. My dad has the book, he's going to find out where else those wires go. I guess if you hit the switch it applies 12V to somewhere inside the shuttle cylinder thing to engage it? If I could find it I guess I could jumper it and see if it drove?

The solenoid on the side of the shuttle is for your declutch. Behind your instrument cluster is a row of circuit breakers, I can't remember which one controls the declutch solenoid, so you can check your book and test you circuits.

Yes! That little stupid button was the culprit :) Took it off and threw in the pile in back of the shop. Figured since we didn't know what it was and my dad's had the hoe for 25 years it wasn't being used. He took it out and it just crumbled sorta, but then the hoe works. Thank you all soooo much, I didn't have to pull the tranny!!

Now back to figuring how to get the 580C working, ugh
