McCauley 192558, Pressure Relief Valve Spring - Tempest PMA
Tempest AG192558-PMA
The Tempest AG192558 (McCauley OEM 192558) is an FAA-PMA replacement pressure relief valve spring for McCauley applications.
- Supports stable governor oil pressure characteristics by providing the intended spring force for relief valve regulation.
- Helps protect internal components by enabling predictable pressure relief behavior when system conditions demand it.
- Improves overhaul repeatability by keeping the relief valve stack built to the correct OEM callout and spring rate intent.
Relief valve spring performance directly impacts how the governor handles oil flow and pressure during transient events. This component is intended for aviation propeller governor maintenance, overhaul, and troubleshooting.
Installation notes
These notes are general guidance only; always refer to the approved maintenance and overhaul manual for complete installation procedures.
- Replace relief valve springs during overhaul when the valve is serviced, and inspect the plunger and seat for scoring or debris damage.
- Perform functional checks per the governor maintenance manual to confirm correct pressure behavior after reassembly.
