A high capacity running tool (11) sets and internally tests a casing hanger packoff (45) during the same trip. The running tool (11) has a stem (13) and a body (25). The body (25) is secured by threads (19) to the stem (13) of the running tool (11) so that rotation of the stem (13) relative to the body (25) will cause the stem (13) to move longitudinally. An engagement element (37) connects the tool body (25) to the casing hanger (39) by engaging the inner surface of the casing hanger (39). Longitudinal movement of the stem (13) relative to the body (25) moves the engaging element (37) between inner and outer positions and lines up ports (15, 17, 33, 35) in the stem (13) and in the body (25) for setting and testing functions. |
