If you do use the gearbox and motor out of a front wheel drive car talk to your friend that rebuilds diffs about welding the diff so that it is posi. You could also have a machine shop make you a solid diff out of a plate of steel and use the spider gear splined sections welded to the steel plate(I have seen this done before). It's usually very strong and since you have the cv's for some play in the shafts you are less likely to explode the setup.

I don't think a locked differential would work... both sides would have always be going the same speed. You could not turn.

[flyinwall]

a locked diff will NOT work as you need to be able to stop one side from turning so that you can steer i have had a CIG locker in a suzuki 4x4 i had and it works well for that situation but will not work in this application

[6X6]

An air locker may work if you set it up to lock when you're not turning, but if you have a failure you loose it most likely, but if it sticks you suddenly can't turn. A limited slip diff won't spin out to one side so easily but will still allow turning (albeit with more force on your brakes) I'd say if the diff works so well with an Argo, they'll work JUST fine in your build.

The system of layout is nearly identical to how the Chinese Argo is layed out, i have some pics around somewhere of how it is layed out if you are interested ill see if i can find them, the best thing about the Chinese 8x8 is it has a PTO that could be used for winch, propeler or hydrolic attachments

i would love to see the pics you have

Interesting idea on the small front wheel drive car engine tranny with brakes for steering. This setup running large truck mud tires would give extra traction, the taller tires would give more ground clearance as well as allow easier climbing over objects. The tires could give the needed flotation, sealed tub would not be needed. water speed should be better due to centerline of tire could be out of water.

I'm new to 6x6's but I know a thing or two about the Suzuki Samurai's...
The Samurai gearbox is a good Idea if you mean the t-case. Its all gear, has high and low with a 1.23:1 reduction in high (stock) and and a huge aftermarket (mine has a 5.13:1 Low range ratio from Calmini.) The best part is that it is divorce mounted (not directly attached to the transmission-it uses a driveshaft) This would give you a lot mounting options and adjustability in regards to ratios. Its also lightweight and bulletproof in a light vehicle. Toyota pickups my be another good source for the diff. You should have a lot of those in "Oz"
my 2 cents.

I agree about the Samurai Transfer case, they are available in your area, are stout, small & serviceable. I've considered the T.C. out of these machines for years
& the compact design lends itself to AATV application. From what I remember the weight is similar to a t20 too.

i dont know why the transfer would be needed but i am considering a zook 1.0 lt motor and 4 speed and i will be using a diff from an indepandent rear suspension vehicle as i dont need all the diff tubes

The Zuk drivetrain is actually pretty long. How big do you want this thing? The main issue I see is Gearing or the lack there of. Everytime you lock one side of the Dif to turn, the other side will double in speed and get half the torque. The Zuk engine is not known for it's power and it might not take the RPM it would be required to in order to compensate for large tires and the differntial issue. Some of the small engines used in these things turn around 10000 RPMS and still only go 25 MPH.
At the risk of being a "devils advocate" how useful would a 4 speed be in any 6x6? Would it be worth the extra size, weight and hassle?
My thinking is this. Will it work? Yes, IF the final gear ratio is correct. Do you have enough opportunity to gear it correctly within the design? I don't know. Argo makes it work so with enough thought I'm sure you can. I'ld find a skid steer transmission and sell a child or two LOL!

i was under the impression that a T20 was a reduction gearbox therefor reducing toe "10000 RPM" down to about 5000 rpm output and the zook motor is about 50hp and im pretty sure that they have a bit more torque than a single or twin cyl motor and since it will be a totaly custom build i can make it all fit but if i can find a 3 cyl front wheel drive i will change my plans (since i havnt started to cut any steel yet i can easily change it)

The t-20 by itself has approx 6.25 : 1 internal drive reduction, but our machines use a cvt belt drive, so the final drive ratio is constantly changing. If you use a direct drive, the only way to make drive ratio changes would be to have a multi speed gearbox.

So assuming the CVT runs as high as 1:1 that would be the same as High gear in a manual-you would need to find a dif of like 3.73 (suzuki samurai) and from the diff you would have to run at about 2:1 between the diff and the chain drive to the axels-Hmmmmm definately doable!
Does anybody know what the range of reductions for the CVT? That would be helpful for any custom build. Exspecially the low range of the CVT (like 1st gear)?
I can't wait to see this thing! Skid steering and "bangin' gears" !!! Now THAT is cool!!
