It appears they are spring loaded, looks like they just popped out of place.
I have a hydro from a 129 that would only go forward, did not even have a neutral, let alone reverse. Could this be from moving around without releasing plungers? I have another hydro that I am installing on that tractor so I can get it back operational sooner, I want to dig into it and see what might be wrong within, largely for the experience of it. I have another nice 129 frame without an engine or transmission, if I can fix this hydro I may look for an engine and try to put this other 129 together..... never have had one of these hydro units apart. I have located a couple of seal/ gasket kits via Ebay that don't seem terribly expensive.
(NO, I am NOT gonna send it in for the $1500 "rebuild service" that is advertised there, for one of these units)
there is a guy about 20 miles from me that has all of the innards of a hydro from a 149 listed on Ebay right now. I'm thinking of biting on it for spare parts.

The slipper feet are crushed/galled and the retainer ring is broken. The feet (the brass things) piled up and cracked the casing. These pistons are not spring loaded, they are hydraulically driven. There is a good article in the tech section on how hydros work. The service manual explains it pretty well, too.
If you are very methodical, and follow the service manual instructions exactly (especially removing the swash plate) and you'll manage. If you put a part in backwards (easy to do)it won't work. So keep everything in exact order.
