O.S. Engine OS74004060 Security Ring for OMA-2810/2815 Brushless Motor  [OS74004060]

Security ring for OMA-2810/2815

The O.S. Engine OS74004060 security ring is a dedicated retention part designed for use with OMA-2810 and OMA-2815 brushless motors. As a scale RC accessory it serves to maintain axial position of the motor shaft and to keep attached components seating correctly during operation.

Intended role: this ring is a simple mechanical retention element that helps prevent end-play and unintended axial movement of the motor shaft, which can affect pinion engagement and drivetrain consistency during tuning or maintenance.

Installation notes: fit the ring to the motor shaft groove sized for OMA-2810/2815 motors, confirm axial seating and free rotation, and inspect periodically during routine motor service. The design is meant for model-scale electric setups and for routine workshop procedures such as gear swaps and bearing checks.
