To remove the CAS drive pin from the camshaft, break off the locating stub from the old CAS pin and drilling a 5mm hole completely threw the pin and tap it with a M6x1 tap.
Thread an M6 bolt into the hole until it contacts the cam behind the CAS pin; continue tightening the bolt until the CAS pin is pulled out of the hole.

This will make the perfect tool for pressing the new CAS drive pin into the camshaft. If not you will need to make a sleeve suitable for pressing the CAS drive pin into place; it must sit snug on the shoulder below the spline section.
