McCauley A-1633-36, 2-202 Body To Base Body to Base O-ring - Tempest PMA
Tempest AGA-1633-36-PMA
The Tempest AGA-1633-36 (McCauley OEM A-1633-36) is an FAA-PMA overhaul 2-202 body to base body to base o-ring for McCauley applications.
- Seals the governor housing joint where body and base components mate, supporting pressure integrity and clean operation.
- Helps reduce repeat leak events after overhaul by restoring proper gasketless sealing at a high-impact joint.
- Commonly replaced any time the base is separated from the body due to compression set and handling damage risk.
This O-ring supports aviation governor overhaul and line maintenance where correct part number cross references keep builds consistent.
Installation notes
Always refer to the approved maintenance and overhaul manual for full installation guidance before starting work.
- Inspect mating faces for nicks or corrosion and confirm correct groove condition before installing a new seal.
- Use the torque sequence and values in the approved maintenance data to avoid housing distortion and uneven seal compression.
