Woodward 180301, Bearing, Idler Gear Bearing - Tempest PMA
Tempest AG180301-PMA
The Tempest AG180301 (Woodward OEM 180301) is an FAA-PMA replacement bearing, idler gear bearing for Woodward applications.
- Supports smooth idler gear rotation to help maintain consistent internal governor operation and reduce wear-related friction.
- Helps restore proper gear support during overhaul when bearing roughness, looseness, or surface distress is found.
- Improves service consistency by matching the OEM-referenced part number used in Woodward governor parts lists.
Idler gear bearings are addressed during governor overhaul because gear train support directly impacts internal motion quality and long-term reliability. PJi® supports aviation maintenance professionals with OEM-cross referenced governor components used in constant speed propeller systems.
Installation notes
Refer to your aircraft and governor maintenance manual for complete installation procedures and torque values.
- Replace the bearing if there is roughness, looseness, scoring, discoloration, or out-of-limit wear per the overhaul manual.
- Inspect the idler gear, shaft, and housing bore for wear patterns that can indicate misalignment or contamination.
- Maintain strict cleanliness during assembly and follow the approved lubrication and functional check procedures.
Applications and fitment
Used in Woodward propeller governor gear train configurations where OEM 180301 is specified. Confirm compatibility by matching the OEM part number and verifying the idler gear bearing callout in the approved parts list for your governor model and serial number.
Tempest AG180301 is the direct replacement for OEM 180301. Confirm applicability by governor model, dash number, and approved parts list before ordering.
