140L Nose-ring Inner Ring Replacement YS Engine YSM0022 for RC Engines  [YSM0022]

140L Nose-ring Inner Ring Details

This YS Engine YSM0022 inner ring is a replacement component sized for 140L nose-ring assemblies. It provides the internal seating surface that aligns and retains the spinner or nose cowl on compatible 140L setups, offering a simple swap when the original ring shows wear.

For installation, ensure correct seating and concentric alignment: remove any burrs, clean the mating surfaces, and press the inner ring home until it sits flush. After fitting, rotate the spinner by hand to confirm there is no binding and that the assembly runs true.

As part of routine maintenance this item is intended as a service spare rather than a performance upgrade, restoring correct geometry and securing the nose cowl after engine work on 140L-configured RC engines.
