ABSTRACT:
A method for mounting removably secured actuator arms that include head suspensions to an actuator assembly spindle. Each arm is mounted to an actuator spindle via a spacer with an annular lip with at least one detent formed into its perimeter edge. Each actuator arm includes two resilient fingers, annularly shaped to form an interior radius smaller than the spacer radius with at least one engagement member formed into a finger. Each arm is mounted by expanding the resilient fingers to a stressed state, engaging the fingers with the lip, and positioning the fingers so that each engagement member is aligned and engaged with a detent. The spacer alternatively includes a guide slot in a planar surface from which the lip extends, with the guide slot being engaged by a boss tower on the arm to properly orient the arm when mounting the arm to the spacer.
