TOH gave a couple pics and they are spot on. No hidden springs to wonder where they came from where they went and no figuring out how to put tthem back once you find em lol
The cup with a hole in it you need 2 per cylinder and are #15 in the other pic. They are what permits the cylinder to move. The V-packing is is to keep the fluid inside the cylinder. I was able to replace the cups without removing the cylinder from loader frame. That was just me and don't have a real workshop to work in (My vise is currently under a ft. of snow) plus I only needed to remove 1 line. I figured using a large pipe wrench towards the end away from threaded part I was less likely to crush it. In my case I was successful. Reinstalling was the hardest part as 1 cup faces backwards and needs to be carefully inserted inside. Oil cup and take your time. Time outs when frustrated is a great idea!
I realize I babble saying how I do things but I'm not an ole hand at most this stuff. In fact the only hydraulic cylinders I have done are on my FEL
