72 580B transmission issues

Walker1 · May 20, 2021

There is a 1972 Case 580B CK.near me for sale for 4 grand. It looks to be decent. Said to run well and no hydraulic issues. It states that it needs a transmission. I assume this is a shuttle shift tranny, not a gear box like on my 530. It would be an upgrade from my 530 if working, so I will consider it.
What transmission issues are these likely to have? What is the difficulty in repair rebuild of them? Is a transmission overhaul within the realm of a user rebuild, or is there specialty tools/machines needed?

thanks,

most likely the shuttle tube clogged.thats common on them.it takes me a day and night to clean mine and get it back together.no special tools needed but a bad job.theres a screen on end of tube that clogs.theres an old post somewhere of how to drill and tap threw bottom of shuttle for easy cleaning.other than that great machines.brakes wear quik

I went up and looked at it. It will move forward, and tries to go backward but wont. I will drag it home tomorrow.
My 530 is a manual transmission and dry clutch, and the others I had used are hydrostatic, so I am out of my league on shifting this one. It appears to be a 4 speed, so I am assuming standard H pattern, however it doesn’t want to go into gear while running, most likely operator error, though the shuttle lever has a crap ton of play, so perhaps I am not holding my tongue right.
The 3 pedals seem to go down together. I am assuming right foot is throttle then left and right brakes and left foot is hold both?
The other hydraulics seem to work great, no leaks or funny noises.
Motor was a little slow to start, but seems to run fine. It was fairly cold where it was, and from the looks of it, it has not run for a few months.

As always, any advice is appreciated,

Left foot is shuttle clutch. It disengages the torque converter. You press the left pedal, then change gears. Next release the left pedal and when you step on the throttle it should begin to move. You can change from forward to reverse without stepping on the left pedal and you can come to a stop without pressing the left pedal

Hmmm, the pedal doesn’t seem to move much, about the same as the brake pedal, about an inch, inch and a half. Perhaps that is why I was having trouble getting it into gear.

I drug it home today. I am surprised at the similarities between this and my 530. It seems substantially heavier though. It does have big wheel weights, and I am curious as to their weight. I hauled it on my 10K flatbed, and it was not near as comfortable as my 530.

The clutch pedal moves the brake pedals, likely due to a lack of lube. It does measure the 3.1”, and itdoes disengage when pushed. The shifting issues appear to be an incredible amount of slop in the shift pattern.
It started and runs decent. The temp and oil pressure gauge are the only working gauges.

It appears it was bought at Richie Bros or the like. It has a decent paint job, but has had a few poorly executed repairs, but they are just metal work, so I will try to fit them into my work stream.

it struggles to move forward and while it tries to reverse it just can’t do it. I am going to drill and tap ‘The Hole’ and see if that is my issue.

Only other real issue is a leaky equalizer cylinder. Sadly, I have the parts sitting in my tool box because my 530 has the same leaky cylinder.

Couple of pictures, you can see my 530 in the background.

Eric a1cnc · May 23, 2021

DAM! That looks like it lived inside it's whole life. No broken loader arms like all the ones I have seen either.

Even your 530 looks really nice from what I can see. Can't tell for sure but your 530 looks to have the same lever as mine which has the case-omatic

What's with you and missing lug nuts?

Walker1 · May 23, 2021

Yeah, well, you have to have few loose nuts to keep dragging 50+ year old tractors home.

it has been refinished at one time and new decals, so it looks better in pictures. The right side loader frame had been cut apart at the pivot for some reason, then a crappy repair. The ROPS has also taken a hit somewhere. I suspect if I unbolted it, it would spring apart.
I like the 530 because it is a 4 speed dry clutch and mechanical shuttle. I like the diesel on the 580. I like the rear hydraulics on the 580. I like that the 530 is more compact and lighter.

If I can get the 580 moving forward and backward reliably, and it will manage a steep grade (24%) then I will likely keep the 580 and sell my little 530. If not, I may swap the diesel into my 530.

One other issue is my backhoe. I had planned to connect my Case/Davis D130 hoe (I had it on my skidsteer, but the buyer didn’t want it) to my 530. I have bracket parts cut out to do it, but not installed. It looks to be a do-able thing to change the bracket to connect it to the 580. Not sure how big of a deal it is to swap from the blade to the hoe on the 580 though. I suppose once you figure everything out it becomes easier.

Eric a1cnc · May 24, 2021

Not sure about out there but here in the Northeast you can find complete model 33 hoes for < $1000 in decent shape. Heck I bought a complete 580ck for $1000 last year. It's not running yet but once I rebuild the engine it will.

I wouldn't bother swapping the engines, an in frame rebuild kit for the 188d is ~$700. Then you have an engine with known parts in it

The motor in my 530 is a gas motor, not a diesel. Old equipment isn’t common or cheap here. Even non running is expensive. I am shocked right now what things are selling for..

I agree! There are a lot of people asking a MILLION dollars for things. I don't know how much is actually selling but....

Everyone thinks their machine for sale is gold and needs nothing.

I bought my machine 18 months ago for about 1/3 of what similar machines were selling for. The guy I bought it from said "all you need is some seals in the one boom piston and you are ready to make money with her". I am not stupid I saw the dent in the cylinder, so no seals were not the issue. Hoses were old and cracking, cab floor was all but rotted away. I knew what I was getting into. She ran moved and everything worked except the brakes. I will be into this machine for about 2/3s of what similar vintage machine are going for. Mine will have been fixed and everything up to snuff vs. an unknown.

If I was going to start an excavating business I would spend more money and get something newer than my 30 year old Cat.

Walker1 · May 24, 2021

For sure, if I was doing anything other than playing on my own property then I would be getting something much newer.

edgephoto · May 25, 2021

I seriously considering spending a ton more and getting a trade in from the Cat dealer. If I did that I am spending 2-3 times what this machine will cost me when done. Plus I will end up with a machine that takes DEF and is full of electronics.

I deal with the latest tech on autos in my day job. We also have electric cars and they are basically driving phones.

Old tech is easy to fix and much cheaper.

Walker1 · May 27, 2021

Well, bad news. I drained 4 gallons out of the torque tube, then drilled the hole to clean the screen. While there was a couple small pieces of debris the screen was largely clean. I did get some debris out, so maybe not a total waste of effort, just a lot of effort for a not the fix.
Get the fluids changed tomorrow and see where to go from there.

It was time well spent because you now know it wasn't a plugged screen !

Luis Sevilla · Mar 22, 2022

Did you figure it out?
I replaced the seals and clutches in mine. Should have it done this weekend.
The clutches looked fine in the shuttle but I replaced them anyways. I beginning to wonder if the torque converter was bad.
