FS-62V Compatible Rocker Arm OS40661100 for O.S. Engine  [OS40661100]

Installation guidance and role

This rocker arm is specified for the FS-62V engine designation and transmits camshaft action to the valve train. It is supplied as a direct replacement option for worn rocker components in FS-62V nitro engines.

Installation notes: remove the head and rocker shaft assembly following the engine maker's service instructions, check the mating faces and pivot for signs of wear, mount the new rocker arm onto the existing shaft, and reassemble with clean parts. Measure valve clearances before making any adjustments and ensure the rocker and valve operate freely before completing the job.

Tuning and maintenance: the rocker arm plays a part in valve timing and consistency of lift under load, so include it in routine inspections to maintain reliable idle and throttle response. Replace the rocker arm if you detect looseness, scoring, or uneven valve seating.
