Sequential 4-speeds mini gearbox instructions

After many requests, I put at your disposal instructions for building the Mini's mini sequential gearbox.




I know that some of the connections and solutions looks needlessly complex, but this is fact so to fit it to the little mini's nose, you can adapt it to your own car.







IMPORTANT NOTE!!!

 - The red rubbers connect both 1 stud bush under the selector, like this:


- You must change the yellow plate 1x4 for a rack 1x4(ref. 3743), this part doesn't exist in LDD :(
- You must change the red axle connector Ridged(ref. 6538a/b) inside the Driving Ring, for an axle connector smooth(ref. 6538c), oriented like this picture:



Finally you can download the LDD file(.lxf) and the step by step instructions in the INSTRUCTIONS page, enter and access to the Download folder

I hope this gearbox will be useful for you!!!

    Yes, the MegaUpload link gives an error message that says "The file you are trying to access is temporarily unavailable. Please try again later."

    Are you sure you didn't accidentally make it private or something? I will try it again tomorrow.

    Well, some of the connections and solutions looks needlessly complex to working in garage, but this is fact so to fit it to the little mini 's nose, you can adapt it to your own car.

    I tried to build a fiat 500 (new) with your chassis. Try a linear gearbox. It took less room, allowing me to but in an L motor for more power in the nose. (line the gearbox parallel to driving motor in nose along floor, or else it gives backlash. But otherwise brilliant. Try a 240zg next. =)

    Thanks a lot!
    It's the first remote and functionnal gearbox I ever build (:
    I think it would be easy to make it automatic, what do you think about it?

    does the rubbers tension mater?

    ReplyDelete
  19. Sheepo05 February, 2012 12:05

    Yes, the rubbers must be very tense. You can use other no-lego rubbers but the high tense is very important.

    Hi Sheepo,

    A photo would do, probably.

    Is there any way to change gears without a motor ? Thank you Sheepo

  23. Sheepo26 March, 2012 22:24

    You can change speeds with a motor or manually, but not automatic, if you are asking that...

    Nice Gearbox, its a similar solution to what I got to with my 5+N+R adaption of your veyron gearbox although you have made the selectors even more compact. I might try to merge the ideas on mine with these and see what happens. However, like previous posts - I am interested how do you precisly pulse the motor for each gear change.

  26. Sheepo08 May, 2012 00:24

    This version is very very compact, and it don't have secuential pulse selector, you must stop manualy the motor when each speed is selected

  28. Sheepo30 August, 2012 20:10

    Sorry, but that is your problem, many people had built it without problems. Look the instructions slow and you will can build it.

    Inside the gearbox, search a flat space for it ;)

    What is the point in the arm across the top? I built it without it and a few modifications and works just fine.

  38. Sheepo24 February, 2013 12:24

    It is only to avoid dissasemble problems, it doesn't have mechanical use.

    I only use Lego motors, so I don't know how you can do it with other motoros, but you can try with small RC cars motors...

    For me it doesn't work right.. shifter gets often stuck between 3rd and 4th gear and I can't move with it, I have to take it apart, fix it and put it back together.
