The new Handle Adapter 860.366.00.0 don't fit the shaft

Help Page

 
Problem:
The older Geberit Handle Adapter square opening is larger because there should be a brass sleeve
that fits inside the large opening.
 
Solution:
The current style Geberit Handle Adapter 860.366.00.0 should fit on the shaft, but you need to remove the old larger square sleeve
from the shaft.
