Inspired by Eaton Fuller FS-6406B. More lego gearbox ideas: www.lugnet.com/~3813/ (ad blocker recommended).

On your transfer case, version 3, what is the gear on the output shaft and how many teeth does it have?

It's old 24 teeth crown gear. It's mainly for bevel gear pairs but here it's to make sliding gear shifting easier than in normal spur gear pair. Can be replaced with normal 24 teeth gear but shifting to low can be more difficult. 🙂
