Overview: Cylinder Head for GT22

This O.S. Engine OS28204000 Cylinder Head GT22 is an RC-scale replacement intended for GT22-series nitro model engines. The text emphasises compatibility checks, routine maintenance steps, and the influence this head can have on cooling and combustion, without asserting any specific performance benefits.

Use the item only as an RC model engine accessory. Have the correct hex driver available, maintain a clean workspace, and follow the engine manufacturer's recommended service intervals when removing the original head. No material specifications or torque figures are supplied here.

At fitment, ensure the head seats evenly against the crankcase and that the mating surface is cleared of old gasket residue. Replace seals and gaskets as advised and inspect glow plug threads and seating before final assembly.

As a direct replacement part for GT22-series engines, this cylinder head should be handled as a precision component during both installation and ongoing service.
