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

Installation and Fit Notes

This rocker support is a scale replacement component intended to secure the rocker shaft area on FS-series engine assemblies. The product carries the "GF40" identifier and is intended for incorporation into FS engine parts assemblies rather than being used as an independent engine unit.

Its principal role is to locate the rocker assembly and assist in keeping valve geometry consistent through tuning or rebuild operations. The focus here is on fit and function, not on stepwise installation guidance.

Replace a worn rocker mount or install this support when refining rocker shaft alignment on FS-series RC glow engines; always verify fit and clearance with your specific engine layout before final fitting.
