Abstract: Tool for extracting annular carbon face seal from bore of equipment which seal is installed. Tool has extraction-tube for insertion into bore at entrance so, when extraction-tube is fully inserted into bore, multi-legged collet formed at distal-end of extraction-tube located within seal and proximal-end of extraction-tube accessible at entrance of bore. Tool has elongate-member extending along central passage of extraction-tube. Wedge element provided at distal-end of elongate-member located at mouth of collet. Proximal-end of elongate-member accessible at proximal-end of extraction-tube. Tool has support for reacting axial extraction force applied to extraction-tube to equipment. Tool has first-actuator at proximal-end of elongate-member. Tool configured so first-actuator causes wedge element to be pulled into collet, thereby expanding collet and causing to grip inner surface of seal.

Abstract: A steering column assembly shroud includes a first member having an end portion which is received within a second member having at least one slit through its wall extending partially along its length. A guide bush is located between the first member and the second member and fixed relative to one of the members. The guide bush provides a surface over which the other member can slide to alter the overall length of the shroud. A clamp mechanism squeezes the second member onto the guide bush which is, in turn, squeezed onto the first member. The cross section of the guide bush varies along its length to vary the resistance it provides to crushing by the action of the clamp mechanism when the shroud is at its greatest length and the resistance it provides when the shroud is clamped at its shortest length.
