New clutch arrives late & ‘ruppelt’ when starting up

At the last big-rep, the clutch was also made new with back bearing and lift cylinder kplt.. So far so good and can be much easier to kick. But…. – Comes very (!) late – When mounting it unmistakably – soft coupling from the stand is not. – In ‘warmÄ condition it gets better – domes between the corridors is no problem Watt iss that now again ??? Workshop says that there is no need to change it. Is there anything to adjust because hydraulic. OK visible. – Is it due to the new clutch/coacher ? (from Kamilli as newly acquired – was not Delphi&Borg, but a Sachs) – Can you do something wrong with the installation ? Tips please ……
