McCauley A-3150-8 / A-3150-18, Tite Split Taper Spirol Roll Pin - Tempest PMA
Tempest AGA-3150-18-PMA
The Tempest AGA-3150-18 (McCauley OEM A-3150-8 / A-3150-18) is an FAA-PMA replacement tite split taper spirol roll pin for McCauley applications.
- Provides high-retention pinning with a taper roll pin design that helps maintain tight fit in the intended assembly location.
- Supports consistent mechanism alignment by preventing joint migration that can occur when a worn or incorrect pin is installed.
- Often replaced during overhaul because taper roll pins can deform, lose retention, or show wear marks that indicate shifting.
High-retention pins are widely used in aviation governor mechanisms where small changes in linkage play can impact response and repeatability.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Use the approved installation tools and methods to prevent pin damage and bore distortion.
- Replace the pin if removed. Reuse can reduce retention and lead to joint movement.
