Hey!
i´m thinking on install this 5 speed kitt to my gearbox. My gearbox is complete 100% new and have NOT roll 1m.
But is it hard to install it if a guy like me dont now to screw with the gearbox? Is this set just a "plug and play" and not change anything?
PS: Is there any guide to install it? video?

Anywone?

Going on that picture I'ld say it's not a plug and play. It looks like you have to replace the whole top shaft which you can only do by disassembly. On the plus side it's not a hard box to take apart. I've done one before (4 speed) and it's a doddle

Yes you,ll need to remove the top shaft and replace it with the one in the picture also add the small gear to the end of the bottom shaft.

Okey, but every gear, 1,2,3,4 is on one shaft? But in this kit it only 3,4,5 or is it complete? What small gear?
-
the 5th gear is the big one on the top of the shaft in the photo. when used with the little gear (the small one that is on its own in the photo) so you remove the old top shaft and replace it with the on in the picture which has the extra gear on it. Then remove the end nut on the bottom shaft and fit the little gear to complete the 5 gear set up. So you keep the old lower shaft but replace the top one. The casing is bigger because of the extra two gears

Okey, i understand little more. i did take of my gearbox today and check it and i did take some photos to se what you all mean.
Is it this i gone change with that new shaft on the photo?

But that "little gear" you talking about i need to fit it, or change it? Is this end nut in that "house"

Do you understand what i mean? :)
-
Yes in the top photo you are right, you remove this whole shaft and fit with the new one.
The little gear fits on the end of the bottom shaft. Can you remove the "other house" cover that's on the end of the gearbox and take a photo? Then I can show you :)

Okey, that sounds good :) its look like i understand now :)
I take of that end house later today and show you a photo :)

Putting together a gearbox is a harder than putting together an engine.
Take a look in the Bis workshop manual. If the clearances are not OK,
you can destroy 1000E in a short time ???

But its not a bis gearbox. Its a fiat 650 aircooled gearbox :/ do you think its hard? I have got relly good information of a guy here how to do, i'm gone show him 1 more photo so i now 100% how to do.

It all depends how mechanically minded you are. I've taken a few gearboxes apart in my time and the 126/500 for me is pretty simple :)

Hey!
i think that i am mechanically. I did not get any time to screw down the gearbox, so i dont have any photo but i maybe can do it tomorrow. If i do it i show you the photo tomorrow :)
have a nice saturday! :)

Hi See another 5 speed box on the horizon,
Ok just to clear up some detail, from memory.
when i got my kit that complete shaft your showning is not included, what it is showing i beleive is how the parts mate together. The main and cluster shaft stay in the box and you work from the back of the gearbox and remove the rear casting that has the selector running through it.
Have you got your kit and is the cluster shaft included? if not great makes life easier.
once you remove the rear casting you need to remove the top selector rod and DO NOT drop the ball bearing inside or then you will need a stripdown including the differental "you have been warned" remove all detent balls and interlocking detent balls first to play safe.
you need to remove the second gear cluster on the rear, this will require you locking the gears together just select 3rd and 4th together and this will do it. the speed drive you remove will need to be slimmed down by about 1.5 mm but you will have to check on the instruction to confirm how much as i dont remember but it is hardened and needs to be done in a machine shop. the rest is easy and just check clearances on things as you assemble. once fitted make sure all turns and selector works with out binding as i found this required modifing, and if i remeber right the middle selector fork needed to be modified but you see this when testing the box just a file will do this. once the box is fitted to the car the coupling link needs to be shorteren by 37mm and the gearbox strut will need to be modified to clear the casting or it will rub on the gearbox. I said a day and that is easily done in a day, a pro can do one in 2 hours so is easy job but follow instruction and hay presto all done. ;)

Hey smallcox!
I dont relly now how the kitt looks but i have look in fiat500sport and did find this kitt: http://www.fiat500sport.com/gearbox-and-transmission/kit-5-speed-with-3-4-5-short-speedfor-126-gearbox-0113.html
I dont now if that is the same kit you did buy?
But all that you wrote did i understand a little. I most read it many times to understand more, but if i ask this simple question. Do you think i can handle it if i buy this kit on the link? Can you guy´s help me if i´m not fix it by my self?
I´m pretty mechanicel, i have strip down a fiat 126 now and gone do the paint jobb. but many people have say here in sweden to, that fix a gearbox is harder to tuning a engine :/ But i think that i still can fix that 5 speed kit in the gearbox. I relly want to have a 5 speed. You did say that the engine has 3500 rpm in 70 mph? That is 110 Km/h here in sweden and we can not drive any faster at the highways.
do you think i can fix it if i order that kit on the link?

Follow instructions and you will be fine and take your time, do not slip 1st gear ring/reverse off the lower shaft as this is a problem to get back in place in situ, and watch how you remove 2nd gear assembly as this has many parts to it and will require to be rebuilt how it comes apart. get a manual on your gearbox and all is straight forward.
Once you done one you can do another in half the time.
