Case 580 CK rear differential way overfull why?

[1968 Case 580CK]

Dad26......Holy Kow Batman! Greased Lightnin is here looking over my shoulder at the computer screen pic of your wounded soldier CK, and she is wimpering and feeling the pain. G. Lightnin then looked down at me and asked , "You aint gonna be askin me to werk like that, are you?" I told her, "Naawww, cause if I did, there is this Marie Louvouee up in Michigan which will fly down and put a lickin on me and leave me with a curse that will take years for me to recover from........so, No Worries Mate". G. Lightnin belched some foul diesel smoke, one big sigh of relief.

I wonder how heavy that boulder was? Maybe 5000 lbs? Plus it probably was not centered, making matters worse. What is the max. load rating on these old rigs?

 

[dad2six]

Hahaha. Not sure how heavy it was. But damn heavy indeed. And no it was not centered. It was a chore just getting it in the bucket. Once I did it was all the way to the right side of the bucket. The left rear tire was coming off the ground so I had to swing the hoe over to that side to put it back on the ground. I have moved 6 boulders of almost this size from my front yard to the backyard. This one made it about halfway.

Diver, probably too much traction from those new front tires. If he had left the old bald ones on there it would have moved that rock easily. ; ) I am surprised that it broke there, though. It could have been a lot worse. D26, I'd find a prominent place for a rock that valuable. I've got a couple at my place that cost me a bunch to move.

D26, The Operators manual says that the breakout force is 6,800lbs and the lift capacity to full height is 3,800lbs. A yard of gravel weighs about 3,200lbs so I would say that your boulder was likely in the 4-5000lb range. Centered, you could chain it onto the lip of the bucket and drag it around but that much weight is hard on anything. When I have blast rock to move, I hire it out and the local excavator makes short work of it. Get the axle off and have a competent welder reattach the piece that broke off. You will have some work to get the spindle off and once repaired, to get it back on. Hopefully, you didn't bend your steering cylinder as they are harder to come by.

D26 ...........Good thing you werent doing this with one of these new plastic kubotas or you would be looking for super glue to put it back together ...........I had a big one i moved with ole Marie and was impressed she could move it but not as big as that one ...........Looks like a clean break if so i would just put her back together and weld the crap out of it drink a beer and be glad you have one of the old ones that you can weld ...........

Prepping for surgery.

D26...........Just wanna throw this out there so hopefully it helps some avoid this problem.........A neighbor of mine was digging sand out of a bank with his 580b and the front tires were sinking in the sand with a load in the bucket (narrow front tires) and it was downhill so when he was backing up the rear tires didnt have enough weight on them and they would loose traction and it was jumping up and down regaining traction now and then..............needless to say but it tore out the ring and pinion gears ..........so when you feel the rearend lifting you might want to rethink things to avoid this since helping him change them gears i try to avoid this now ............If you move them this big you might grab a rock with that backhoe to help keep weight to the rear and keep those tires on the ground....

I know it sucks to have breakdowns but at least you can fix this one............You will have her back up and running in no time.....

 

[Grady]

Xpack, When I was a lot younger, a guy who knew a lot more than me felt obliged to remind me that an old 580CK is not a bulldozer and that the rear end is the weak link. I guess D26 might argue and say the front end but I think that was just his warning shot. That front end will fix a lot cheaper and easier than the rear end will. Now, my approach is if the hoe won't move the big ones, I call on a bigger machine. It isn't worth killing the ole girl to move a rock or three. She'll move hundreds of rocks a little smaller but only one if it's too big. D26, unless I'm mistaken, the king pin tube is cast [steel?] and the front axle frame isn't. Do you need to preheat the cast before welding it to the frame?

 

[onemank6]

Grady ....Some of the stumps i dig up are huge and heavy so rather than try to get these big boys in the bucket to move them i just roll them to move them so i dont tear up the tractor ......I definitely have made my share of mistakes with tractors over the years and kick myself in the A-- when i realize it could of been avoided .....I almost think its just human nature to push these tractors to their limit before backing off and thinking about what can and will break..I try to think things out more now than i used to when im operating them these days but i still have a brain far- now and then and it usually cost when i do.........

 

[Grady]

xpack, I agree. When you're in the seat, you're usually trying to get something done and the consequences of what could happen to the machine aren't always first in your head. With me it usually depends how long it's been since the last time I did something that cost me plenty. Even without pushing it too hard, I've found out that if you use it - you'll break something sooner or later and it's usually sooner on these old ones but just about everything can be fixed. It's just usually more fun working with it than on it.

 

[dad2six]

I fixed the front axle a while back and have move a lot of earth since.
I bent the crap out of the draglink.



Bent that back straight with my press.
And have been putting in some long hours in the seat working on the rock wall.

I moved two dump truck loads full yesterday. 26 tons of boulders until my manual thumb had enough.



Time to build a stronger one.

 

[Juskatla]

D26, That's some job you and your CK have taken on. The one thing about these old machines is they are simple to repair and parts are still plentiful. I don't do heavy rock work with mine anymore and hire the local guy with a JD excavator. I had lot of fun moving blast rock, but I couldn't swing and stack like a good excavator operator can. You are lucky to have a lot of open area to work and the ability to fix whatever breaks. Thanks for the pics...

 

[dad2six]

I also wanted my kids to experience operating the hoe.
Here is my 11 year old daughter running it.

Does the park brake work?

 

[dad2six]

What park brake?

 

[1968 Case 580CK]

Dad2Six.......Amazing......You break them, and you fix them. And the 580CK is like the old Timex Watch.....
It takes a Lickin,
And keeps on Tickin.

I think that Dial (Dale) of Tractor Stuff needs to open a branch office up near your homesite. You could save a ton in shipping costs on new parts. Ha ha. Your daughter is doing great at working those backhoe levers, with or without the parking brake.

Thank you, all my kids got some seat time and loved it. I'm glad it's a tough old bird. I make her work hard.

 

[dad2six]

Made a new link for the thumb. 1/4" wall DOM tube for the ends and 1/4" wall square tube center. Should hold up much better. It must weigh at least 3 times what the old one did.

Here is a little video for ya
Working on the wall this morning. I'm operation Lafonda with only one hand while holding my phone so it's a little more jumpy than normal. And yes my wife has named her Lafonda.

Amazing work! Super heavy duty! Shoot, the maker of that attachment should be contracting to you to make a few hundred of those suckers.
