The liner hanger assembly seals with casing 8 and supports a liner 98 within a well. The tubular liner hanger 48 and a tubular expander 40 may be position downhole on a running tool at a desired depth along the casing string 8 . An actuator assembly 6 may forcably move the tubular expander 40 into the tubular hanger, expanding the liner hanger to seal and secure the hanger against the casing string 8 . After the running tool has been removed, a seal nipple may be sealed to the sealing sleeve of the tubular expander. A selectively releasable clutch 73 is provided for allowing rotation of the liner to rotate the liner with the running tool, and thereafter to disengage and release the running tool from the set liner hanger.
