McCauley A-1635-87, Motor Clamp Screw- McCauley - Tempest PMA
Tempest AGA-1635-87-PMA
The Tempest AGA-1635-87 (McCauley OEM A-1635-87) is an FAA-PMA replacement motor clamp screw for McCauley applications.
- Provides OEM specified fastener fit to maintain proper clamp load and retention under vibration.
- Supports consistent assembly alignment by preventing clamp movement that can lead to wear, fretting, or intermittent issues.
- A smart replacement during governor service when hardware condition is unknown or when the assembly has been disturbed.
Fastener integrity matters in propeller governor systems because small changes in clamp load can create bigger reliability issues over time. This motor clamp screw is supplied for aviation maintenance and overhaul where technicians and buyers cross reference the OEM part number to ensure correct replacement.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Use the torque value and any locking compound or locking device specified in the governor maintenance manual.
- Inspect the clamp and mating surfaces for deformation or wear that could reduce clamp effectiveness even with a new screw installed.
