6x6 via backwards 205

[David Witcher]

Hey how are you guys, Im a nwebie here with a Question. I want to build a 6x6 using a divorced 205 behind my 241 turned backwards. 1 input and 2 output to a pair of 14bolts using twin driveshafts.
The rear axle will be pointed up with a double CV drive shaft supported by a carrier over the fornt rearend via a crossmember. The million dollar question is could the 205 live in 4 high at freeway speed in reverse direction.

Well why can't you run int in 2wd on th asphalt?? no need for it to be turning all four rears when theres lots of traction.When you get to a bad spot, just put it in 4 hi. But to answer your question, it should last a while bu i think all the unloading loading of the gears due to drivetrsin bind would be hard on it.

try a AWD 203 it has a sort of differntial in it and wouldnt bind up like a 205 would

I think it's time to swap in some rockwells if you want a 6x6. All you would need would be a short driveshaft between the axles.

sounds way too complex and weak. Too many shafts and weak parts for my liking. Relying on a 241 to spin 6 wheels and that much weight sounds like a mistake to me. 3 Rockwells would be your best bet for 6x6. Its the way the military does it. How will you run the driveshafts? I mean what if the farthest back axle wants to droop down and the middle one wants to go up? 14 bolts are big, I doubt you'd get it to work without driveshaft issues.

I forget which one specifically, but one of the old New Process transfer cases (NP200, NP201, NP202) has a provision for a 2nd rear output. I think its the 202 that came in the Dodge M37's and the Jeep M715's, but I'm not sure. Anyway, you could run this case divorced behind a 2wd tranny and get your 6x6. Only problem I could see is that the PTO boxes might be a little hard to find if you wanted one, because I don't think they have the regular 6 bolt SAE pto cover, but instead a larger 10 bolt cover.

It works...just run it in 2wd on the road. I've seen severial rigs do it and am planning on doing it myself.

The problem with using rockwells is the gearing...sure they are great for 44's but I am using mine as a tow rig and will have around a 31" tire.

6x6 via 205 backwards

As far as the 241 its a DLD model behind a NV4500 with a Cummins in front of that so I think It should be strong enough. Using a 203 could be tuff trying to mount divorce style.
Rockwells are waayyy out of the question.
This thing has to be a tow rig.
And running the thing in 2 high, Im going to check the T-case, that maybe possiable (duh) Thanks.
