OK, it’s got the two-seal setup.
A 27mm socket made an ideal “special tool” to use for pressing.
The inner seemed to have been installed rather clumsily (from new I guess) being rather distorted, the metal insert being dented on its face; the outer was considerably worn, the inside diameter being 0.063 larger than the inner seal’s inner diameter!
The rotor drive sprocket shaft surfaces are not in good condition, as pictured.
I have ordered two replacement seals for each side, one R21, one R23 (one with, and one without without auxiliary dust seal), although I can’t really see the point, bearing in mind the state of the metal surface, the outer will likely wear rapidly.
Gasket paper ordered too. I suspect 0.8mm Flexoid is OK (I have ordered some 0.5mm too just in case).
