Claim:
1. A tool for retaining an activator ring of a hanger within a wellhead assembly during a fluid pumping process, the tool comprising: a fluid pumping sub body having a proximal end selectively coupled with a supply of fluids and a distal end selectively coupled with the hanger; an outer ring assembly circumscribing and rotatable relative to the fluid pumping sub body; a retainer ring circumscribing the fluid pumping sub body that selectively abuts the activator ring, wherein the activator ring is axially moveable relative to the hanger; and a plurality of biasing assemblies that are selectively axially compressible between the outer ring assembly and the retainer ring, so that when the fluid pumping sub body is coupled with the hanger, an axial lockdown force is maintained on the activator ring by the biasing assemblies during the fluid pumping process: wherein the activator ring is positioned to engage a lockdown ring such that the lockdown ring moves radially in response to axial movement of the activator ring.
