Deere 460 Bucket Cylinder Help

[GBrown]

The bucket cylinder on our Deere 460 loader (4700 tractor) is leaking. Serial: W00460X009667
If anyone has experience in disassembling the cylinder in the attached pictures, I will appreciate instructions or even where there may be a tutorial for the overhaul. I've rebuilt cylinders on other implements but these are different from experience.
Thanks for all help.

I believe there is a slot at the top of the cylinder barrel that has a lock wire in it. The wire is fed out through the slot while you turn the gland.
