Fit and function overview

The OS74004060 security ring by O.S. Engine is made for use with OMA-2810 and OMA-2815 brushless motors as a shaft retention component. It secures axial placement so attachments remain properly seated through operation.

Functional role: this ring prevents end-play and unintended axial drift that can upset pinion engagement and cause inconsistent drivetrain behavior during tuning or use.

Workshop notes: install the ring into the shaft groove specified for OMA-2810/2815, verify smooth rotation and correct axial position, and include it in routine servicing tasks such as gear or bearing swaps.

How strong is the retention provided by this ring?

It offers a mechanical stop to limit axial movement; strength depends on correct seating in the shaft groove and should be checked after fitting.

When is the best time to replace the ring?

Replace the ring if you detect deformation, excessive wear, or if it no longer seats securely during routine motor inspection.

Will fitting this part change my gear mesh setup?

The ring itself does not change gear spacing, but by holding the shaft position it helps keep previously set pinion mesh consistent.
