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

Inner Ring for 140L Nose Assemblies

The YS Engine YSM0022 inner ring is a replacement part crafted to fit 140L nose-ring assemblies on RC engines. It forms the internal seating that locates and retains the spinner or nose cowl, allowing worn assemblies to be returned to correct running geometry.

Proper installation requires attention to the housing and the ring face: clean both surfaces, remove any imperfections, and press the ring evenly until it is seated flush. Rotate the spinner by hand after fitting to ensure there is no binding and that the assembly runs concentrically.

This piece is intended as a maintenance item rather than an upgrade; it restores the correct fit and holds the nose cowl securely following routine engine maintenance on 140L-configured units.
