Case 580CK transmission repair Part 6. Nearing the End

[@MyLifeThai371]

I can see you really love that machine. You even decided to wear a shirt that is the same color as it!

[@Timberland-Farms]

That’s just a coincidence 😂 but I do really enjoy this machine. My dad had one very similar 1971 CK when I was 5 or 6 before he traded up to his 580K

[@carlpetersen5983]

awesome job thanks for the video, i just bought a 1975 case 580B CK backhoe and excited to watch you film you rebuilding the transmission. please let me know why the hyd fluid is milky in the tractor

[@Timberland-Farms]

Most likely water in the hydraulic system or transmission, hydraulic and Tractor HY-Tran are Hydroscopic, meaning they absorb moisture by design, so water doesn’t get trapped somewhere in the system, I suggest replacing the fluid, the hydraulic system for the loader and backhoe can use any hydraulic oil, but the tractor can only use TCH or HY-Tran or similar. I just use the TCH/HY-tran for all systems and it’s most cross compatible with all my equipment

[@deecember69]

I keep neutral and let shuttle shifter into forward while tractor warms up. Keeps a lot of wear off clutches pre warming that oil.

[@Timberland-Farms]

That’s a good idea especially when it’s cold. My dad with his 580K lifts the back tires up and lets it run in gear to warm up

@@Timberland-Farms does your accessory side of key stay hot when in on position? Mine did and the heater stayed hot, damaging relay before I got it. I put a momentary button beside key now ran through on side to heat intake. I wondered if the accessory and on position connected had another thermal breaker that tripped instead to kill power to heater after a bit?

[@Timberland-Farms]

@deecember69 I’m in the middle of the “restoration” (I’ll use that term loosely) so I currently have no wire harness in it, just battery cables and a button switch for the starter

[@Timberland-Farms]

@deecember69 this backhoe had a momentary button beside the key switch before hand

@@Timberland-Farms It looks great! Keep up the videos they help us all!

I have the same machine, my Dad bought new, I still have the sales receipt from the dealer and with the Cat controls my Dad ordered it with it was 6400.00 brand new. I'm currently repacking the cylinders again and should have it running again soon, over the life of the machine I've put a radiator, starter, injector pump, and many multiple oil changes, the engine has never been opened up and the tractor has never been split.

[@Timberland-Farms]

They are tough machines for sure. I have no idea the history of this machine but in the 3 years I’ve had it, I finished putting a replacement engine in, radiator, swing cylinder and stabilizer cylinder packing along with the shuttle clutches

[@Anthony-o2w1s]

$6,400 is insane. In good shape they bring that much today!

[@Timberland-Farms]

@user-wd2nf7wn4o equipment holds its value for sure

[@justindailey4265]

Hey man thanks for all the great videos. I have the same tractor I noticed the trans fluid is milky, how should I remedy this situation, also does this machine have a filter on. The trans?

[@Timberland-Farms]

Sounds like you have water in your transmission oil. If you have a power shuttle machine like mine, they are very picky on the transmission oil. They take HY-TRAN or comparable like a TCH fluid. Hydraulic oils are typically hydroscopic, which means they attract moisture and trap it with the oil itself. It’s designed so water does not get trapped in your hydraulic system. I suggest you replace all your fluid. If that’s too pricey you can sometimes get by with a turkey fryer and “boil” the water out of the oil. Maintaining 212°f or more for several hours until the milkyness dissipates. As for the filer, yes my machine has a transmission filter located behind the grille in addition to a hydraulic filter located on the loader mast framework that is in charge of the attachment hydraulic like the loader and backhoe attachments

@@Timberland-Farms thanks for the info. How do I know if I have a power shuttle? I went to the dealer and they told me to put 80-90 gear lube in the transmission I think this is wrong information.. I can try to post a pic of the machine so u have a better idea. Mine is late 60s I believe and has the ROPS I believe it’s a ck580 B but I’m not positive

[@Timberland-Farms]

@justindailey4265 the 580B has twin cylinders on the hoe side by side unlike my 580ck in the video. I only have the one cylinder on the hoe. One for the stick and another for the bucket, no twins. And yes it takes 80w-90 gear oil for the transmission. That is where the 4 speed transmission and rear differential is located, it is separate from the shuttle assembly. Do you have a forward and reverse selector on your dash? Do you have to clutch to change gears or directions? The power shuttle is clutchless and has a foward and reverse selector on the steering column or dash with a 4 speed transmission

[@justindailey4265]

@@Timberland-Farms my hoe looks like yours, I have a forward reverse selector on the dash, no clutch the gear pattern is a 4 speed with a start position, there is 3 covers on the floor. One where the west is attached one with the shifter and the one under the dash. I pulled the dipstick on the one under the dash and that is where I have water mixed in the fluid. What is that chamber?

[@Timberland-Farms]

That one under the fuel tank and steering column is for the torque converter, that holds the TCH/hytran.

Great job

[@Timberland-Farms]

Thank you! We have a little more work left to do but the hard part is all wrapped up and I’m stoked

[@ZoltanNagy-c5k]

Install the missing counter weight infront of the front axle its a must .

[@Timberland-Farms]

If I can find one locally I will. The machine will balance so much better. It’s an optional counterweight at around 700 lbs. it’s standard for a 900 lb weight to go with the extendahoe. I’ve thought about melting down lead wheel weights from cars into some box to mount in that location also

[@ZoltanNagy-c5k]

@@Timberland-Farms I have a 580 ck with the dig more extendahoe I have the 700 pound counterweight water filled front tires .Love this machine also have the 3 point hitch with a Gannon can change from one to the other in about 15 minutes.Mine is manual clutch with hi low 4 speed trans .

[@ZoltanNagy-c5k]

Also any parts you can find that you might need get them if funds allow they are getting scrapped out to the point of hard to find stuff now.

[@Timberland-Farms]

@user-uu3bi9ge2h looking back, manual clutch with a shuttle would have been nice on this , I have a 3 point hitch also and a Pto but the way the torque converter works I won’t be able to use the backhoe for much farm work, baking hay, mowing…

[@Timberland-Farms]

I get them as the wife allows 🤷‍♂️😂

[@markreading6377]

My transmission needs done on my case 580b but it does not need to look perty like yours

[@Timberland-Farms]

If it’s just the shuttle that needs replacing, you can remove the hoe and split the transaxle from the shuttle transmission instead and save some time
