Fred, thanks for taking the time to reply. I went to a very reputable hydraulic trade counter this morning, I don't want to offend anyone but the supplier is a national company. Total waste of time, the guys I spoke to said we don't strip out rotary couplers; just replace them. Any road up, I went t...

Fred, Jeremy, if either of you have the time to view the images. I can't work out whether the individual seals between the ports are synthetic material?

Any further advice would be appreciated.

Jeremy, thanks for the reply. Pipes are pretty sound, definitely the spool seals leaking. I stripped off the cover plate today, I can clearly see the seal behind a small steel retaining ring. Only thing I can't work out is how to replace? The plunger is a larger diameter at the controls connection, ...

Hi Guys, newbie here! I have a hydraulic leak on my control block joysticks, just thinking of stripping top cover plates to investigate. Does anyone have any experience of a repair/ replacement? I don’t even know if I can source parts, maybe I am wasting my time stripping out? The plungers are leaki...
