A molten metal pump includes a base member submerged in the molten metal, a support member supported above the level of the molten metal by a post extending from the base member through a clearance bore in the support member and a coupling securing the post to the support member. The coupling is mounted to the support surface and includes gripping members operable to a locked position engaging the upper end of the post and to an unlocked position releasing the post. The coupling is aligned with the clearance bore in the support member to permit the post to be assembled or disassembled by axial movement through the clearance bore when the coupling is in the unlocked position.
