McCauley R5673, Ball and Cage Bearing Assembly - Tempest PMA
Tempest AGR5673-PMA
The Tempest AGR5673 (McCauley OEM R5673) is an FAA-PMA replacement ball and cage bearing assembly for McCauley applications.
- Supports smooth rotational movement by maintaining a retained ball and cage bearing element in the intended assembly location.
- Helps reduce roughness and wear progression when an older bearing shows contamination, corrosion, or uneven running surfaces.
- Common overhaul replacement because bearing condition directly affects repeatability and wear debris generation inside high-time governor assemblies.
This bearing assembly supports aviation maintenance and overhaul workflows where Tempest and OEM part numbers are used to cross-reference Garwin governor replacement components. Public NSN style listings for R5673 describe it as a bearing retainer and balls type part with an outside diameter value commonly shown as 0.7370 inches, which can help with identification, but final eligibility must be confirmed with approved governor data.
Installation notes
Always refer to the applicable aircraft and governor maintenance manual for complete installation procedures.
- Keep bearing components clean and protected until installation to avoid contamination-related wear.
- Inspect mating races and supporting hardware for matched wear and replace components as required by approved overhaul data.
Applications and fitment
Used on Garwin governors where OEM R5673 is specified. Confirm compatibility by matching the OEM part number and verifying governor model and serial number applicability in the approved maintenance data.
Tempest AGR5673 is the direct replacement for OEM R5673. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
