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

Security ring for OMA-38 motor

This is an RC-scale security ring designed specifically to interface with the OMA-38 motor family. It functions as a retention component that helps keep the motor assembly stable inside the motor mount or housing during routine assembly and 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 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.
