All case tractor hydraulic cylinders need some serious reviews regarding the way those things are made and assembled. It makes no sense to design cylinder glands that are extremely difficult to repair. The spanner wrench holes suck. There is no reason why the face of the cylinder gland could not be mfr. thicker for a pipe wrench or hexed for a wrench to fit. And what's with the 1/8" diameter screw? Piece of crap breaks off every time. None is needed or use something bigger like 1/4 diameter. We should be able to repair the damn things in the field when necessary and not have to take parts into some machine shop, where they use a torch to get them apart.

Not sure how or why you are having such trouble. I just rebuilt every hyd. cyl. on my Case 580 backhoe the winter of 2013. 13 cylinders total. I never had any problem with the little locking screw (8/32 x 1/4 or 3/8" in length). This screw is designed to lock the gland from turning after it has been tightened. Works very well for what it is intended to do. You need to remove the screw before trying to loosen the gland. You also need the special gland removal spanner wrench (I think I paid less then $50 for mine). Made removing the gland a breeze.

I have that special wrench and if you bother to do some research you will see there are a lot of people complaining about how difficult it is to remove the gland. Many have complained of breaking the pins on those wrenches. I tried using them with fence poles 8 feet long for leverage and still it does not loosen the gland without a torch. Also, there is no reason for the stabilizer pin to be installed with so little clearance that they rust to the point where you have to cut them out with torches. There is no reason for that silly little screw. The gland does not and will never unscrew no matter how many time you use the cylinder. A tractor is not an aircraft that requires extra precautions. No other cylinder mfr. uses the silly screw. There is a heck of a lot of space in front to mfr. the gland with some surfaces to grab with a pipe wrench. This morning I am torching another case 580e stabilizer foot pin that was first cut into 2 pieces and those 2 won't move even after sledge hammering them. Go figure. ....

All-righty then. I do sympifise with you about the stabilizer pins getting rusted so tightly. I had to use 20 tons of press pressure, plus rosebud heat and a lot of Kroil to get this one out.

See the attached photos of what's wrong with case mfr engineers. Not shown are the buggered 4 holes too. Upon reinstalling I needed a long breaker bar all the way meaning the threads are a size 5 fit which is wrong for this application. It only requires a size 3 fit. So it helps to file the thread lands down a bit. Also the seal would be a lot easier to install had the undercut been made closer to the surface and no so far inside. Better yet designing the gland into 2 pieces bolted together for easier replacement of seals. ....

I use to work for a large (at least then) heavy equipment manufacturer and we used a lot of hydraulic cylinders. It has been about 30 years and a lot has changed but does Case make their cylinders? Since they have been bought have they changed their cylinders to what is on New Holland. I have been told and no way do I know if true or not, now only the color is different now between the two.
