Four-Speed Gearbox Model

This educational building set lets builders assemble a functional four-speed gearbox using interlocking plastic bricks. The kit includes all necessary pieces and PDF instructions for a complete model. It is designed for ages fourteen and up and appeals to hobbyists interested in mechanical engineering concepts. The set carries the MOC-45647 designation and contains 188 parts.

Suited For Mechanical Learning

Builders who want a hands-on demonstration of gear ratios and transmission mechanics will find this set valuable. It also works well as a display piece for brick-technic collections. Younger children under the recommended age may struggle with the complexity and small components. Collectors seeking licensed Star Wars models should look elsewhere, as this is an original mechanical creation.

100% LEGO Compatibility

Every brick in the box is designed to connect tightly with standard LEGO studs and tubes, allowing the gearbox to be integrated into larger builds. The ABS plastic pieces hold together firmly during operation and disassembly. This compatibility is the single specification that determines whether the set fits into an existing brick ecosystem.

Questions about this item

How does the 4-speed gearbox in the MOC-45647 set behave once it is built?

The completed gearbox lets you shift through four distinct gear ratios by hand, showing how torque and speed change with each selection.

What building system does the set use for its connections?

The bricks follow the standard LEGO-compatible stud-and-tube geometry, so they lock firmly with genuine LEGO pieces and other major brands.

What space does the finished model need for display or play?

The assembled gearbox fits on a typical desk or shelf; its footprint is small enough for a standard baseplate.
