End of tranny input shaft was smooth. A bit grimy/dirty, but I wiped
it off, and it felt smooth.
I greased the pilot-bearing with some grease on my pinky, as the
pilot-bearing was quite dry. But pilotbearing felt very smooth too.
Couldnt tell if the pins were rolling though. But felt OK.

Didnt check this.Couldnt see felt. Looked like I was looking direct
at marked face of pilot-bearing.

No, unfortunately not, I didnt think enough of checking those. AURGH
- had I only read the Haynes step by step when working my way throu
the clutch-job. But it was one of those days where I wanted to
believe that I had the "magic touch" to be able to repair my car,
without being traumatized by the descriptions in the Haynes. SIGH!!!!!!!!!!!!

Yes, ball socket intact and cup intact - and a smear of nice new copper-grease.
I will look at the slave-cylinder, see if there is enough throw on
the pistion, or if I have to change it.
I will look at freeplay at the mastercylinder/pedal linkage.
Best regards
Jens Jakob
