When I look at the day corrector or the setting lever with wheel, it looks like its climbing on the minute wheel while its griping into this and it sort of trying to get to the right sort of.. I have to take it a part again..
Thanks all but the price of the Horotec tool is a bit prohibitive... I have managed to free it with a very sharp piece of peg wood in one of the cut outs and push it round..The bearing is OK its just that the balance needs some work and you cant remove it with the rotor in place.
To remove the beaing you need a special tool but just to remove the rotor you just take of the three screws holding the automatic mechanism, turn it around and unscrew three small screws on the underside and the rotor gets loose..
Could take a couple of shots for you if you wish..
