Abstract

See full text

A method for adjusting the axial position of a first member relative to a second member, the first member being threadedly connected to the second member such that rotation of the first member relative to the second member results in axial movement of the first member relative to the second member. The method includes the steps of providing a piston assembly having an annularly extending cylinder and an annularly extending piston which is slidably received in the cylinder, the piston assembly being operable to extend and retract the piston relative to the cylinder; positioning the piston assembly coaxially relative to the first and second members such that the cylinder is engageable with one of the first and second members and the piston is engageable with the other of the first and second members such that, upon activation of the piston assembly, the piston assembly rotates the first member relative to the second member; and activating the piston assembly to thereby rotate the first member relative to the second member and thereby move the first member axially relative to the second member.
