ABSTRACT:
A spacing mechanism is provided for locating at least one rotatable component relative to a stationary component of a mechanical seal. The spacing mechanism is configured to automatically disengage from the rotatable seal component, and/or its associated hardware, upon rotation of the rotatable seal component. The spacing mechanism may be configured to axially and/or radially locate one or more rotatable components relative to one or more stationary components and may be configured to automatically disengage from the rotatable seal component by the rotation of the rotatable seal component.
