Hi Joeyd, I saw your thread and that's the area I was trying to uncover to grease/re-grease and check the balls to see if they were plastic or steel. But...I got stuck at trying to remove the black plastic cover just on top of the joystick lock? How did you get it removed?? I just couldn't seem to find an appropriate way to get it to come up and off. Sure didn't want to break it either! My joystick looks practically identical to your pictures.
As far as the cables connecting to the valve spool, I assume one can remove the cap/cover on the valve at that end also? You said that you - adjusted - the cables by screwing/unscrewing the ends? I didn't quite see where the adjustment function was located? I sure would like to get some type of motorcycle chain lube sprayed into the cables to assist them in remaining flexible - slide-able also. Even if it isn't needed, I don't see how it could hurt any? Any further advice/thoughts would be appreciated. Thanks, Greg
