Lego Ferrari 488 GTE Manual 8 Speed Gearbox
This video shows the design and construction of an 8 speed manual gearbox inspired by the Lego Technic Ferrari 488 GTE model that has come out in 2021. The lego technic set is called set #42125 Ferrari 488 GTE "AF Corse #51".
The gearbox gearing ratios closely approximate the gearing ratios of the real Ferrari 488 GTE gearbox except that it implements a lego technic manual 8 speed gearbox instead of an automatic 8 speed gearbox.
This lego gearbox design implements the gearing ratios of 7 forward gears and one reverse gear matching the gearing ratios of the Ferrari 488 gearbox.
The design process to create the correct gearing ratio approximation is shown from paper design to actual implementation. The final model is demonstrated by driving an 8 cylinder lego technic engine using a large PF (Power Functions) motor and switching between all of the 8 possible gears.
This gearbox does not fit into the Lego Technic Ferrari 488 GTE model #42125.
