Woodward 1418-820, Thrust Race Bearing - Tempest PMA
Tempest AG1418-820-PMA
The Tempest AG1418-820 (Woodward OEM 1418-820) is an FAA-PMA replacement thrust race bearing for Woodward applications.
- Supports smooth thrust load transfer, helping maintain stable RPM governing performance and predictable control response.
- Provides a serviceable wear surface that can be replaced during overhaul when bearing faces show scoring, spalling, or out-of-limit wear.
- Matches the intended replacement configuration for Woodward governor thrust race applications under the Tempest governor replacement parts program.
Thrust races are often replaced as part of a comprehensive governor refresh to reduce friction, improve repeatability, and support long-term reliability. PJi® supports aviation maintenance professionals with OEM-cross referenced governor components used in overhaul and line replacement.
Installation notes
Refer to the applicable governor and engine maintenance manual for full installation procedures, torque values, and inspection requirements.
- Confirm that AG1418-820 is the correct race for your governor dash number. Multiple thrust race variants exist and are not interchangeable without verifying the bearing stack design.
- Inspect mating bearing elements and replace as needed to prevent uneven contact patterns and early wear.
- Use approved lubrication, cleanliness, and assembly procedures per the governor overhaul manual.
Applications and fitment
For Woodward propeller governors. Confirm compatibility by matching OEM 1418-820 and reviewing the governor illustrated parts catalog and overhaul data for your specific Woodward governor model and dash number.
Tempest AG1418-820 is the direct replacement for OEM 1418-820. Confirm the correct thrust race selection by governor model, dash number, and the bearing stack configuration in approved maintenance data.
