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

Replacement gasket for FS-62V engines

The O.S. Engine head gasket labeled OS40614000 is intended as a service replacement for FS-62V RC nitro engines. It provides the combustion chamber seal between head and crankcase, so correct seating and surface condition are important for consistent compression and smooth running.

This gasket is designated specifically for the FS-62V family. Do not assume fitment on other engine types without checking the official parts list or consulting an authorized parts supplier.

Before installation, ensure all mating faces are clean and free of old gasket material, and that head and crankcase faces are flat. Replace the gasket whenever the head is removed, and use the manufacturer's recommended tightening sequence and torque values to avoid distortion.

Role in tuning: a properly fitted gasket keeps compression stable during tuning steps such as needle changes or head shimming. Compression loss caused by a faulty gasket can be mistaken for other tuning faults, so include gasket checks when troubleshooting.
