Thanks Daantjie,

I am so slow. I have received the new balls and they are 7.000mm

I have installed them (24 pieces!) and discarded the old balls.

The new balls 'feel' okay.
However I have only a torque instrument that can measure downb to 20Ncm, maybe 10Ncm.
I am trying to get a torque measuring tool that can measure 5 Ncm or smaller. I have printed a fitting in order to be able using a 1/4" drive to move and measure the torque for the assembly steps and adjustments according to the manual under 46-220.

As soon I have a proper instrument for measuring these small torque values can move further.

One note: I have used up almost all seal rings. I think I have another smaller o-ring left and I don't know where this is going yet. I am mentioning that because some people said there are many seals left over from the reseal kit.... which is not the case.

Best, Martin
