So the most common thing I see on old backhoes is the hoe is just loose as hell. I was watching a 580C for a few and man was the hoe moving while the guy drove it around. Is that expensive to correct or do people not care? The old case hoes I used had slop and got a tad annoying but the backhoe today I watched was far worse; I would go NUTS. I was just curious about that and thought I'd ask.

Seems to me most people just don't care. I don't know how much a re-pin and bushing job would cost on a backhoe, but that would be the fix. Just think of it this way; if you come across some utilities while digging, you'll have a little wiggle room. The 580SL I'm running at work has 6300 hours, it slops around a little but not too bad. I don't mind the slop as much when I'm actually using the hoe, it actually irritates me more when you tuck in the hoe and are running around, hit some rough ground, and the whole back end of the machine does it's own thing. To me, that's almost more irritating.

our one 580 super M does it...it gets a little annoying when you are doing loader work, just have to reach behind you and push the lever to fully retract the cylinder every now and again....it has nothing to do with pins and bushings...it is an O-ring inside the control that is bad and allows the pressure to seep out of the cylinder basically allowing it to go into "float" so it smacks back and forth against the machine stop and the boom lock

Yeah I had to do the same thing for my hoe, just push the control forward to bring it back. The only thing with the hoe I was watching is that it's side-to-side was very bad. So if you replaced the O-ring it should go away then?

You're right, the slop from the hoe bouncing back and forth when running around with the seat facing forward is from hydraulics bleeding off. I just assumed that coopers was talking about pin and bushing slop, I can handle that, but the bleed off is definately more of a hassle for me. I must've re-tucked in the hoe like 10 times yesterday in 5 hours time. Not that big of a deal, but it always seems to get you when you least expect it. Hit a bump and you're fine, 2 minutes later the hoe is slapping all over the place, almost like the problem comes from nowhere.

Slop is not too bad, if you are carefully scraping off soil, and the bucket tip catches the pipe, it might save the edge from piercing, I've had that happen 3 times now while "looking" for gas and electrical lines. But when the bucket actually self levels itself, it's time to head into the shop.

replacing an O-ring is as simple as replacing an O-ring...its getting to that O-ring that is the major problem...put it this way, we have one hoe that needs the boom O-ring replaced and one hoe that needs the dipper stick O-ring replaced...my boss talked to some Case mechanics and after what he was told he is waiting until the dead of winter when nothing is going on the bring them into the shop and tear them apart.

haha, yeah that's what I thought. Well at the very least I'll be making sure mine don't go long without replacement. My old boss had to take apart his extendahoe to do some work and I'm glad I wasn't there for that.

The swing slop isn't too bad, just gotta be quick on your feet if you're running Case controls. You really have to be in the machine for a little bit to teach yourself to compensate for the overswing. We had 3 hoes at the grounds with Case controls, every single one of them were completely different when coming back into the trench in regards to the valving in the swing pedals and the slop that goes along with the age of the hoe. We had a Cat 436, ancient machine, probably built in the mid 80's I'd guess. The worst swing slop I have ever seen. However, I was able to smoohtly pull the cycle in and out of the trench like it's no big deal, even with Case controls. Just takes a little time with the machine to understand what it's going to do. It's all about being familiar with the machine, if you know what it's going to do, you can compensate in advance.

Lol, yeah it is an art to dig with a sloppy hoe or bucket. I certain had to find the best way to compensate for that, afterwards I never noticed the slop until I was using the other end driving around.

All backhoes have swing slop it doesn't matter if its brandnew or not. You have two short hydraulic cylinders pushing against each other to swing the boom back and forth. The JCB I used to run it had boom slop you just had to take account for it when swining. The machine only had 2500 hours on it and the machine is regularly greased non of the pins were worn out.

I'am used to working with a backhoe I probably put 100kms just roading the machine that doesn't include using the machine on the sites. Bounce bounce and more bounce who needs

Case foot pedal swing is the worst for a wild swing but it all takes practice.

Well since this is kinda on case backhoes I just had to share some pics of a nice looking 580C that I found sold on point2 which was really on ironplanet. Anyone that can appreciate an old hoe would like this.

Thats a oldey you don't see many of them anymore especially a open ROPS.

Just imagine those machines is what the older operators cut their teeth on a bare bones basic machine no fancy pilot controls.
