3045 hydraulic cylinder seal replacement

[ca3045zetor]

I just acquired a 3045 tractor that has been sitting for 14 years. It fired up but all the hydraulic cylinder seals are bad and spitting out Milky fluid. (leaking fluid at seals). I have removed all the rams but don't know how to remove the end caps. The C-Clips have been removed. Do these unscrew? Is there a retaining Pin? are the pressed in? I have the replacement kit for all the seals but don't know how to change them.

Any suggestions?

Thanx
