Hornby Schools Class R2742X 21 Tooth Replacement Gear – Single

Looking for a replacement gear for your model railway locomotive? This independently designed, resin 3D printed replacement gear is intended for a compatible mechanism.

What's included:
One replacement gear (21 Tooth).

Before ordering:
Please check the original gear's tooth count, outside diameter, bore, thickness, hub dimensions and tooth profile. A matching tooth count or locomotive name alone does not guarantee compatibility. Contact us with your model reference and measurements if unsure.

These are independently produced resin 3D printed parts, not original manufacturer spares. Some fitting or minor finishing may be required. Exact compatibility is subject to verification.
