Garwin 2-111, 7/16 ID X 3/32 Control Shaft O-ring - Tempest PMA
Tempest AG34-2111-PMA
The Tempest AG34-2111 (Garwin OEM 2-111) is an FAA-PMA overhaul 7/16 id x 3/32 control shaft o-ring for Garwin applications.
- Seals around the control shaft to help prevent seepage and maintain internal oil pressure integrity that supports consistent RPM control.
- Common overhaul replacement when the governor is disassembled, especially if leakage, hardening, or compression set is observed.
- Helps reduce maintenance rework by restoring proper sealing at a frequent leak point when installed using the approved procedure.
This O-ring is intended for aircraft constant speed propeller governor service and is commonly used in legacy Garwin governor installations where cross referencing by OEM number is the fastest way to ensure correct replacement.
Installation notes
Refer to the applicable governor and engine maintenance manual for full installation procedures, torque values, and inspection requirements.
- Replace any O-ring that shows cuts, flattening, hardening, or chemical swelling.
- Use approved lubricant and installation technique to avoid twisting or nicking the seal during assembly.
Applications and fitment
Used on Garwin governors where OEM 2-111 is specified. Confirm compatibility by matching the OEM part number and reviewing the applicable governor and aircraft maintenance data.
Tempest AG34-2111 is the direct replacement for OEM 2-111. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
