Beschreibung
Zusammenfassung:	A liner hanger setting mechanism (75) comprises a tubular pump down plug receptacle (80) having a plug seat (86) defined therein, a cylindrical pump down setting plug (170) having a central flow passage and a rupturable member (184) disposed therein to prevent flow therethrough is dropped into a work string (40) and the tubular plug receptacle (80). The pump down setting plug will engage the plug seat and pressure can be increased to the setting pressure required to set a hydraulically actuated liner hanger. The pressure can then be further increased to the rupture pressure of the rupturable member (184) to provide for full bore flow through the pump down setting plug.
