Woodward 6851-207-2, Adapter Disc (Cover Holes) - Tempest PMA
Tempest AG6851-207-2-PMA
The Tempest AG6851-207-2 (Woodward OEM 6851-207-2) is an FAA-PMA replacement adapter disc (cover holes) for Woodward applications.
- Helps ensure correct seating between the governor cover and the coil adapter assembly so clamp load is distributed evenly.
- The cover holes configuration matches Woodward assemblies designed around drilled or vented cover geometry in this adapter family.
- Commonly replaced during overhaul to restore fit, reduce looseness, and support reliable assembly alignment.
In aviation governor maintenance, small discs and adapters like this are often renewed because they directly affect how the stack fits and holds alignment under vibration.
Installation notes
These notes are general guidance only; always refer to the approved maintenance and overhaul manual for complete installation procedures.
- Keep mating surfaces clean and burr free to avoid stack distortion that could affect alignment and clamp load.
- Confirm this is the correct cover holes disc for your governor configuration and that any roll pins or retainers are serviceable.
Applications and fitment
Used where OEM 6851-207-2 is specified for Woodward governor adapter disc applications. Listings commonly separate cover holes and cover no holes variants in this family, so confirm configuration by governor model and illustrated parts breakdown.
While adapter discs are common in many control systems, aircraft governor parts must be installed and verified per approved data and airworthiness requirements.
Tempest AG6851-207-2 is the direct replacement for OEM 6851-207-2. Confirm cover holes configuration and applicability by governor model and serial number in approved maintenance data.
