Head design for GT22 engines

The O.S. Engine OS28204000 Cylinder Head GT22 serves as an RC-scale replacement for GT22-series nitro model engines. This text highlights fit considerations, stepwise installation points, and how the head can influence cooling distribution and combustion tuning without making performance claims.

Use this component as an RC engine accessory only. Prepare a suitable hex driver, keep work surfaces clean, and follow the engine manufacturer's recommended service intervals when removing the original head. No material specifications or torque numbers are provided here.

On assembly, verify the head seats evenly on the crankcase and that mating faces are free from old gasket residue. Replace seals or gaskets as recommended and check glow plug engagement before completing reassembly.

This item functions as a direct replacement head for GT22-series RC engines and should be treated as a precision part during fitting and maintenance.
