Woodward 182738, 1 3/16" ID X 3/32" Cross Section Coil O-ring - Tempest PMA
Tempest AG182738-PMA
The Tempest AG182738 (Woodward OEM 182738) is an FAA-PMA overhaul 1 3/16" id x 3/32" cross section coil o-ring for Woodward applications.
- Helps prevent oil seepage at a coil-related sealing interface by restoring correct O-ring size and compression.
- Supports dependable governor performance by maintaining intended sealing integrity in oil control passages.
- Improves maintenance repeatability by matching an OEM-referenced seal size used in Woodward governor parts lists.
This seal is commonly replaced during governor reseal work and overhaul when multiple internal and external sealing points are refreshed to improve reliability. PJi® supports aviation maintenance professionals with OEM-cross referenced governor seals used in constant speed propeller systems.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect the groove and mating surfaces for scratches, corrosion, or debris that can compromise sealing.
- Use an approved lubricant if specified by the manual and avoid twisting the O-ring during assembly.
- After assembly, verify leak-free operation per the governor maintenance manual requirements.
Applications and fitment
Used in Woodward governor configurations where OEM 182738 is specified for a coil-related sealing interface. Confirm compatibility by matching the OEM part number and verifying the seal callout for your governor model and dash number in approved documentation.
Tempest AG182738 is the direct replacement for OEM 182738. Confirm the coil seal location and size by governor model and approved maintenance data before ordering.
