ABSTRACT:
A pre-load mechanism has a self-mounting coil spring that resiliently forces a pre-loading member against a pre-loaded member. The spring has an active helical-coiled portion that is resiliently expandable and contractible in axial length to set the pre-load force and a mounting coil portion that has an interference fit with the mounting member for allowing the pre-load force to be set by forced positioning of the mounting coil portion on the mounting member to a calibrated position, and once the pre-load has been so set, for maintaining the mounting coil portion in the calibrated position as the active coil portion expands and contracts in axial length. The mounting coil portion has non-circular helical convolutions with protruding lobes that bear against the mounting member.
