Exploring the Tamiya 89916 4-Speed Crank Axle Gearbox (Clear)

The Tamiya 89916 4-Speed Crank Axle Gearbox presents a clear view of gear trains for anyone learning about mechanical systems. Its transparent housing makes it straightforward to follow power flow and gear engagement during operation.

Exposed Gear Arrangement

The green and grey gears are visible through the clear case, helping you observe tooth contact, direction changes and the effect of each speed setting. The four-speed layout offers a practical range for testing performance under different loads.

Educational Use and Kit Fitment

Well suited to classroom demonstrations, hobby experiments and integration with Tamiya construction sets, this gearbox provides a hands-on way to explore gear ratios and mechanical design principles.

Is the gearbox easy to mount in a model?

Yes, it is designed for straightforward mounting with common Tamiya parts and basic fasteners. Check alignment and secure mounting points to ensure smooth operation.

What load limits should I expect?

This gearbox is built for light to medium hobby loads and educational use. Avoid subjecting it to heavy continuous torque as this can accelerate wear or damage gears.

Are spare gears or parts available?

Replacement parts are often available through parts suppliers that stock Tamiya components. Keep the original part numbers to find matching spares for gears and fixings.

Any tips for classroom demos?

Run the gearbox at low speed while pointing out tooth engagement and direction changes. Use simple loads and show differences between the four speed settings to illustrate mechanical advantage.
