Can anyone help me with where to start. Bought a 1974 case 580B. Several hydralic cylinders leak heavily. They still work, but the pools of fluid are getting too common on the property. Although it does keep the grass down. How long to repack/rebuild cylinders? Any special tools needed? Special cuss words? Any tips or tricks? Not sure I want to know the cost. The worst is the ram by the bucket, but two others are bad. The Hoe sat for several years before I bought it.

I am fairly handy but my wrench turning has been on cars and not hoes..... Thanks

Derek,
You might try asking your local dealer/shop how much they charge to build the cylinders. I just had 4 of them done for my 450B track loader and the average cost per cylinder was around $35. I about hit the floor when he quoted to me that average cost was about $40. When I bought the machine I was expecting to pay $100 plus per cylinder. There is a spanner wrench that you need to use to get the end cap off. A pipe wrench may do it, but the right tools are nice. There is also a special torque amplifying wrench that I read about in my Case manual. One of my cylinders is supposed to have 1200 ft. lbs. on that big nut at the end. That is alot of torque, so I figured best bet was just carry the cylinders to them.

Good luck if you do it yourself. I expect I may try it next time myself.

Thanks,
David

I am working on the cylinders on my 580. I made my own spanard wrench. it only took me 25 minutes and has works grate so far. I used two pieces of 3/16" X 1" flat bar 14" long. I drilled and bolted one end of each piece together to form a V. on the other end of each piece I drilled a 1/4" hole and put a piece or 1/4" drill rod in it long enough to fit in the pin holes on the cylinders. I welded the pins on the back side of the flatbar. The V joint will allow the arms to be opened or closed depending on the cytlinder size.
Good luck
Chris

Derek, 580 B cylinders have a round head machine screw threaded into the joint between the packing gland and the cylinder barrel. Remove the screw first , then with pin spanner unscrew the gland from the barrel. remove rod and piston from barrel, remove piston retaining nut . From there things are obvious. There is a number stamped on the packing gland, you will need that number to get the right packing. Local hyd shop says they can't buy the kits any cheaper thru their supplier than from case, they go to case dealer.

If the chrome coating on the cylinder shaft is pitted, then you would probably be wasting your time putting a set of seals in. You might be able to find a suitable ag type replacement cylinder at a farm store- but be sure the pins are the right sizes.

If the chrome plating is still good then you will need to remove the bolts that hold the end of the cylinder on, pull the end off and the shaft and piston out of the bore, take the large nut off that holds the piston onto the threaded end of the shaft (I belive they call this the gland nut). Take off the piston. Slide the shaft out of the cylinder end, then replace the end seal. You might as well replace the rest of the seals while you are in there. I did my first hydraulic seal replacement a month ago. Its very time consuming with all the cleaning- you have to make sure there is no dirt on the parts as you put them all back together.

Head for your local Hydraulic shop, I've been working on my 680CK hoe and all the kits for the cylinders on that are at or below $35.00 (each).
Your Case dealer will want substancially more.

I agree with Bob on if the cylinder shaft is scored to any great degree and if after taking the cylinder apart you find scoring in the bore of the barrel you are in trouble.
Minor scoring can be polished out but the heavier stuff will only cause more leaks down the road.

Thanks for the tips...I think I will try it next month... There does not appear to be much pitting.
