Woodward 1418-812, Thrust Race Bearing - Tempest PMA
Tempest AG1418-812-PMA
The Tempest AG1418-812 (Woodward OEM 1418-812) is an FAA-PMA replacement thrust race bearing for Woodward applications.
- Supports smooth thrust bearing operation to help maintain consistent governor response and stable propeller RPM control.
- Provides a replaceable wear surface that helps protect adjacent components when bearing contact surfaces show wear or scoring.
- Matches the intended Tempest FAA-PMA replacement configuration for Woodward governor applications.
This thrust race is commonly replaced during overhaul and repair when bearing surfaces show distress, or when a full bearing stack refresh is performed as part of reliability-focused maintenance. PJi® supports aviation maintenance professionals with governor parts that map to the OEM identifiers used in manuals and work orders.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Always confirm the correct thrust race variant by parts list and bearing stack configuration before installation.
- Inspect mating bearing elements for brinelling or spalling. Replacing only one surface in a damaged bearing stack can shorten service life.
- Maintain strict cleanliness during assembly to prevent premature bearing wear.
Applications and fitment
For Woodward propeller governors, including installations where Woodward model A210800 reciprocating engine speed governors are installed.
Confirm compatibility by matching OEM 1418-812 and validating the thrust bearing stack in the governor illustrated parts catalog for your specific Woodward governor dash number.
Tempest AG1418-812 is the direct replacement for OEM 1418-812. Verify the correct race selection by governor model, dash number, and approved maintenance data.
