FS-62V Head Gasket Replacement OS40614000 - O.S. Engine  [OS40614000]

FS-62V Head Gasket Overview

This O.S. Engine head gasket is an RC replacement part carrying model number OS40614000 and intended for FS-62V engines. It seals the combustion chamber between the cylinder head and crankcase, so correct surface contact and a proper fit are essential for steady compression and reliable running.

Compatibility is limited to the FS-62V family as indicated by the product designation. Do not fit this gasket to other engine families without verifying compatibility using official parts documentation or an authorized dealer.

Installation notes: clean mating surfaces thoroughly before fitting, remove all old gasket residue, and make sure the head and crankcase faces are flat. Replace the gasket whenever the head is removed and follow the engine maker's recommended head nut tightening pattern and torque values rather than generic settings.

Tuning role: a correctly installed head gasket preserves the combustion seal so the engine holds consistent compression during tuning actions such as carburetor adjustments or head shimming. A poor seal can mimic fuel or timing faults, so inspect the gasket when diagnosing irregular idle, low power, or inconsistent running.
