Nose-ring inner ring for 140L

This YS Engine YSM0022 nose-ring inner ring is an RC-scale replacement component intended to fit 140L nose-ring assemblies. It functions as the internal seating element that aligns and retains the spinner or nose cowl on compatible 140L-sized assemblies, providing a straightforward replacement when the original inner ring shows wear.

Installation focus should be on correct seating and alignment: inspect the housing for burrs, clean mating surfaces, and press the inner ring into position until it sits flush. After installation, rotate the spinner by hand to confirm there is no binding and that the ring maintains concentric alignment with the nose assembly. Regular inspection during routine engine maintenance helps detect wear before it affects spinner balance.

In a tuning or maintenance workflow this part is a maintenance spare rather than a performance upgrade, used to restore correct geometry and secure the nose cowl after service on RC engines employing a 140L nose-ring configuration.
