O.S. Engine OS74004004 OMA-38 Motor Security Ring  [OS74004004]

OMA-38 Motor Security Ring Overview

This is an RC-scale security ring engineered to mate with the OMA-38 motor family. It serves as a retention part that helps keep the motor assembly stable inside the motor mount or housing during routine assembly and during track-side adjustments.

The ring is intended for use only with OMA-38 motors and related assemblies where a matched security ring is specified. When planning installation or setup, confirm that the OMA-38 designation matches your motor model to ensure correct fit and function.

Installation notes: the ring is fitted onto the motor assembly as part of final mounting and is used to reduce axial movement of the rotating assembly. Fitment should be checked after first runs and after any disassembly, as part of routine maintenance and tuning of your RC powertrain.
