Tempest AG34-828-15-PMA
The Tempest AG34-828-15 (Garwin OEM 34-828-15) is an FAA-PMA replacement drive gear for Garwin applications.
- Supports reliable drive transmission inside the governor, helping maintain consistent governor response across power changes.
- Helps preserve correct gear mesh and timing when replaced with the proper matching components and clearances.
- Commonly replaced when tooth wear, pitting, or damage is found during inspection, or when geartrain debris indicates abnormal wear.
Gear integrity is critical in aviation constant speed propeller governors because geartrain issues can drive performance symptoms and maintenance downtime.
Installation notes
Always refer to the approved maintenance and overhaul manual for full installation guidance before starting work.
- Inspect mating gears, bearings, and studs for matched wear and replace as required to prevent accelerated wear.
- Verify backlash, end play, and assembly requirements per the approved governor overhaul procedures.
