Beschreibung
Zusammenfassung:	A retention device for maintaining a first rotary machine component (10) axially loaded onto a second rotary machine component (12) in a fixed axial position includes a lock block sized and configured to move between first and second aligned recesses (60,62) in the first and second rotary machine components (10,12). The aligned recesses (60,62) are shaped to prevent rotation of the lock block, and the lock block has a threaded bore (72) extending therethrough. An actuator (74) is threadably mounted in the bore (72), such that rotation of the actuator (74) will, in use, move the lock block from the first aligned recess (60) at least partially into the second aligned recess (62).
