Woodward 182798, 9/16" ID X .103" Cross Section Control Shaft O-ring - Tempest PMA
Tempest AG182798-PMA
The Tempest AG182798 (Woodward OEM 182798) is an FAA-PMA overhaul 9/16" id x.103" cross section control shaft o-ring for Woodward applications.
- Helps prevent oil leakage around the control shaft by restoring correct O-ring size and compression at a high-motion sealing point.
- Supports stable RPM control by maintaining intended sealing integrity where the governor control linkage interfaces with the housing.
- Improves maintenance outcomes by matching an OEM-referenced seal size used in Woodward governor parts lists.
Control shaft seals are commonly replaced during reseal and overhaul because shaft motion and long-term heat and oil exposure can degrade elastomer performance over time. PJi® supports aviation maintenance professionals with OEM-cross referenced governor seals used in constant speed propeller systems.
Installation notes
Refer to your aircraft and governor maintenance manual for complete installation procedures and torque values.
- Inspect the shaft surface for scoring, corrosion, or wear that could cause leakage even with a new seal.
- Use an approved lubricant if specified and avoid rolling or twisting the O-ring during installation.
- After assembly, perform the required operational check and verify there is no seepage around the control shaft.
Applications and fitment
Used in Woodward governor configurations where OEM 182798 is specified for control shaft sealing. Confirm compatibility by matching the OEM part number and verifying the seal callout and shaft configuration for your specific governor model and dash number in approved documentation.
Tempest AG182798 is the direct replacement for OEM 182798. Confirm the control shaft seal location and size by governor model and approved maintenance data before ordering.
