FS Engine Parts Rocker Support GF40 for FS Engine Parts - OS49464000 by O.S. Engine  [OS49464000]

GF40 Rocker Support Overview

This rocker support is an RC-scale replacement designed to stabilise the rocker shaft area on FS-series engine assemblies. The designation includes "GF40" as the part identifier, and the unit is intended to be used inside FS engine parts layouts rather than as a standalone engine.

In service the support locates the rocker assembly to help retain consistent valve geometry during fine tuning or rebuilds. The description emphasises correct fit, the role in setup, and practical installation considerations rather than step-by-step instructions.

Fit this rocker support when replacing a worn mount or when refining rocker shaft alignment on RC glow engine FS-series assemblies; always verify physical fit against your engine layout before completing installation.
