O.S. Engine OS44961400 rocker support for FS engine parts stabilizes rocker alignment to improve repeatability during tuning sessions.
Installation notes: confirm fit with the FS series mounting points and follow the engine's service access procedure, use correct torque on fasteners and ensure alignment before final tightening. This part is useful when testing small adjustments and comparing results across runs.
Tuning role: with a fixed reference for rocker geometry, the support lets you make incremental linkage changes and assess their effect on engine response reliably.
