McCauley B-20159, Paper Die Cut Gasket Cover - Tempest PMA
Tempest AGB-20159-PMA
The Tempest AGB-20159 (McCauley OEM B-20159) is an FAA-PMA overhaul paper die cut gasket cover for McCauley applications.
- Helps prevent oil seepage at the cover joint by providing the correct gasket profile and thickness for the intended cover interface.
- Supports stable governing by maintaining proper sealing between internal cavities, reducing the risk of pressure loss or internal bypass caused by a damaged gasket.
- Common replacement during inspection and overhaul because paper gaskets can compress, tear, or take a set after service heat cycles.
This cover gasket is intended for aviation use in McCauley governor maintenance and overhaul workflows where OEM part number matching is critical for fitment accuracy.
Installation notes
Always refer to the approved maintenance and overhaul manual for full installation guidance before starting work.
- Clean and inspect both mating faces for nicks, warping, or old gasket residue before installing the new gasket.
- Use the torque value and tightening pattern specified in the approved maintenance data to avoid cover distortion and uneven gasket compression.
Applications and fitment
