FS-62V Rocker Arm Replacement - Hardened Steel OS40661100 by O.S. Engine  [OS40661100]

Function and fitting of the rocker arm

This RC-scale rocker arm is specified for the FS-62V engine designation and transfers camshaft motion to the valve train. It is supplied as a replacement component intended to restore correct valve actuation on FS-62V nitro engine assemblies.

Installation notes: remove the cylinder head and rocker shaft assembly following the engine maker's service procedures, examine mating surfaces and the rocker pivot for wear, install the replacement rocker arm on the original shaft, and reassemble with clean parts. Do not change valve clearances without accurate measurement, and confirm smooth, free movement of the rocker and valve before completing reassembly.

Tuning and maintenance: the rocker arm influences valve timing and lift consistency under load. Regular inspection during scheduled engine service helps preserve idle stability and throttle response. Replace the rocker arm if excessive play, surface scoring, or uneven valve seating is observed.
