I don't know if you did it, or if it matters, but I lightly oiled both sides of right where the seal rides on the rod. I figured it could not hurt.
Mike's Subworks also sells pushrod seals. That is what I used on my RCAB cylinder.
I have not tested it yet. I discovered dropping my wtc on the ground packing for the regatta had done servo damage and a few other things, so I am redoing my cylinder now.
Fortunately, everything will be fine.
