Summary:A setting tool allows setting a hydraulic liner hanger in a deviated wellbor e. Subsequent to setting the liner hanger through pressure developed within the setting tool, the setting tool is reconfigured to allow full-bore passage therethrough. In the preferred embodiment, the flow communication to the liner hanger is inter-rupted after it is set so that the setting tool can have a full-bore clearance for passage of cement wipers or other devices and that pressure can then be applied in the setting tool to complete the cementing operations for the liner, as well as to actuate any casing or isolation packers.
