Rudder bearings, Whitlock / Lewmar

[affe304]

Got a Whitlock Cobra steering column with rod and rod ends from whitlock/lewmar between column and rudder. This makes me Think that the rudder shaft, rudder ball cage bearings (with delrin balls) and rudder shaft sleeve(?) is from Whitlock/Lewmar aswell.

Problem:
The lower ball bearing has slided out from the sleeve to create a big play. The small bolts that holds the lower bearing in the sleeve is gone because of the big play between the sleeve and the bearing.
I am trying to get the rudder shaft out from the bearings but it seems stuck.
There is 3 small screws in the upper bearing that seems to hold the shaft into the bearing, one of them is stuck.

Does anyone recognize the sleeve, shaft and bearings shown in the Pictures and got the experince of changing them?

A breakdown Picture would be nice.
