I don't fully understand your question... . if your asking if there was some shipping pin that had to be removed by the dealer, the answer is no... . nothing is done to modify, or predelivery the clutch from the time it left the factory...
The end of the slave cylinder has a round pin that pushes the fork in the bell housing and the only roll pins that can be used are on the quick connectors that hold the lines to the master cylinder and slave cylinder on some installations... . these are not used except to change those parts if necessary...
At the time the slave cylinder is shipped in a box, it has a plastic strap that keeps the rod pushed into the slave against spring pressure and once the slave is install this strap breaks... . the plastic button on the end of the rod is attached and stays in place... .
Hope this helps.....
