I have one of them, bought in a job lot, been meaning to strip it for a while..A second hand Skoda.
Not the car, but a revolving centre in its original box. Looks and feel in good nick.
I took it apart. No grease in it but oil. Cleaned it and filled it with EP2 Lithium grease as that bit of paper states.
Nice bit of kit. Three bearings and adjustable preload.View attachment 497508View attachment 497509View attachment 497510
