The Tempest AG34-828-26 (Garwin OEM 34-828-26) is an FAA-PMA replacement retaining ring for Garwin applications.
- Maintains correct component retention and axial location to help prevent internal movement that can create wear, debris, or control instability.
- Helps support consistent governor operation by keeping the retained component seated in its designed groove.
- Common overhaul replacement if the ring shows loss of spring tension, distortion, corrosion, or installation damage.
Retaining rings are small parts with big consequences in constant speed governor reliability.
