PWA85688 Puller – Jackscrew, Variable Stator Vane Actuator Aircraft Engine Maintenance Tool

Brand: Junxun

The PWA85688 Puller – Jackscrew, Variable Stator Vane Actuator is a specialized Pratt & Whitney aircraft engine maintenance tool designed to support the controlled removal of the Variable Stator Vane (VSV) actuator using a jackscrew pulling mechanism. Aviation tooling references consistently identify PWA85688 as “Puller-Jackscrew Variable Stator Vane Actuator” and classify it among engine tooling for the engine fuel and control system.

The dedicated puller provides a controlled mechanical interface for actuator removal, helping technicians perform VSV actuator servicing without relying on general-purpose extraction equipment. It is also listed in the 2026 Airbus tool lease capability documentation.
