Claim:
1. A method of setting an expandable liner hanger in a subterranean well, the method comprising the steps of: releasably securing a liner hanger setting tool to the liner hanger with an anchoring device that includes a collet releasably engaged in a recess of the liner hanger and the collet being outwardly supported by a support sleeve, the setting tool including at least one piston which displaces an expansion cone through the liner hanger, the expansion cone being positioned between the anchoring device and the at least one piston; and conveying the setting tool and liner hanger into the well on a generally tubular work string by applying sufficient pressure to an internal flow passage of the setting tool to downwardly displace the support sleeve, thereby unsupporting the collet and allowing the collet to disengage from the recess and release the anchoring device, wherein no portion of the liner hanger extends longitudinally between the expansion cone and the work string.
