I have a Ford 770 loader with a leaky bucket cylinder. I've ordered the
rebuild kit, but can't figure out how to dismantle the cylinder. Ones I've
done in the past have had a slot cut into the side of the cylinder where a
square piece of wire gets fed into a slot around the inside of the cylinder.
When the retaining wire is fully inserted, there is a small nub sticking
out, so it can be grabbed for removal. This cylinder has what appears to be
a round wire of some sort with no visible end to grab for removal. I've got
a few pix of the slot here:
