Got the wild idea today to put a second T-19 in my Scout II. Anyone here ever run a dual tranny setup or have any info on it? Know of any links or sources of info on this? Thanks for humoring me on this one........(the cold winter months in the garage can really start to get the better of you :rasta: )

dual trannies and dual t-cases

WoW. Stickem both in low and reverse and go forward real slow.

Actually I'm looking into installing a divorced 205 behind my D20.

Anybody know where I can get a coupler/adapter to hook 'em up?

You'd likely have to make that one yourself.

Isn't that called a driveshaft?:flipoff2:


As for the dual tranny idea...I find it strange that you suddenly mention that you thought it up when it was recently mentioned somewhere else on this board:flipoff2:

I don't know if you were making fun of him or me....anyway in my defense I thought he was referring to the mthod with wich to mount the 205 so that it matches up to the D20.

I figured the D-shaft was way to obvious that it meeded to be stated.

my dream is a wide box behind a 727 their has gotta be a way

Mostly I was just being a smartass (or a dumbass-depends how you look at it):D

YeeeeeeHaaaaaw

I never said that I orginated the idea. I just said that I got the wild hair up my ass to look into doing it to my Scout. :flipoff2: back at ya!!!!!

Okay.......here we go...
I've got a 392 in my scout II with a dana 20 transfer case and behind that I have a divorced 205. Now if you are serious...e-mail me. It can be done... I now walk beside the scout as it idles on the trail.:rasta: :smokin: :flipoff2: :p :p :p :p :p :p :p :p :p

OK, serious question:

whats your rear driveshaft like??

and

did you just do a ujoint between the two, or a very short shaft??



got pics??

My Buddy Eric, has had a married Dana 20 into a Devorced NP205 for about 10 years now, They just share a U-joint, Hes got a 115:1 crawl ratio (T-19 wide, dana 20 np205, 4.56's) and he also walks next to the scout on the trail. He has awsome control with that cral ratio. The set up has lasted him well, he did blow a Dana 20 out put with it though, but it might be the 6.9 Diesels torque that did that one, its broke a AA adapter to. To bad hes retiring the truck.

I'am at 135 to 1 whith 465-203-205-513's not low enough.

BITE me dammit :p

Steve and Terra-izer,

Guess I worded it wrong, huh? But I did get one of ya!

I went out and looked at my buddies 67 F**d 250. The driveshaft between his SM420 and 205 looks to be about a foot long. It ain't stock. I'd think ya'd need to get 'em a lot closer togerther in a Scout.

Will they hook up with just a u-joint twingst them?

Looks like my rear d-shaft would end up shorter than the front.

Rotate the rear up and use a CV.

It will definately remedy the severe angle of my front d-shaft.

Probably will not have to twist the knuckles when I go full-width SOA.

Remove the 20s front output and saw and weld up the case.

Damn near makes it a bolt in.

127:1

Yeeeeeeee Haaaaaaaw!!!!!!!

TORC,

My dad made a rear steer log skidder with dual trannies back in the 60s out of an old Studebaker 2 ton. I called him last night to see how he hooked them up. He used a 392 hemi from a 59 Chrysler and whatever auto it had. To hook the Stude's 4 speed he used two slip joints and and welded one onto the input shaft of the standard. Kinda crude but worked well for the app. I doubt he ever had it over 10 mph.

How about dual trannies and dual t-cases? WOW!!!!

Don't think I'd need two t-cases.... with a T-19 wide, T-19 close, D300 and 4.88's I'd get 325:1 low low and a shit load of optioins up to that!!!! Just gotta figure out how to mate them in as short a length as possible...:bounce: :bounce2: :bounce: :bounce2: :bounce:

It's cuz you have them fawken huge tires--High speed wheelin' Yeehaw



Hey Torc...I say do a double tranny...I'd like to see someone actually create something useful on this board instead of the normal bolt-on crap...

Hey Torc...I say do a double tranny...I'd like to see someone actually create something useful on this board instead of the normal bolt-on crap... Next year we go wheelen and tel me if is high speed.And I made my own adapter but for the Dana 300, 500 hp I think not.

I am trying to set up a dual Dana 20 to Dana 20 married set up, but I can't find the one missing piece - except from people who want lots and lots of money for it. The Bull gear - 10 spline with 26 tooth outer. I have had people ask as much as $150 for this gear.:rolleyes:
The best offer was $12,:D but, it turned out to be the 6 spline. I have had several people help by looking, & I thank them, but I am still in need for the gear to make this project happen. Anyone got one for a reasonable price?

Ritch :usa:

I thought about trying to do a D300-D300 married set up at one time. Bolt patterns an such would probably be the same as your D20-D20 set up. Don't know if the same bull gear would work or not. I wonder how easy it would be to adapt your set up to a D20-D300 married set up. How much $$$ you got in it so far? Compared to what a Creeper Box or Klune V cost, $150 bucks sounds pretty cheap to me. Do you already have the adaptor plate worked out to join the two? Did you cut the front output portion of the front case off and weld it up?

As for the dual trannies, I was thinking the easiest way to go would be just some sort of internally splined sleeve to join output shaft to a shortened and reworked input shaft. That would still leave several inches between the two cases.... i would like to figure out a way to butt the cases together with no (or minimal gap bewteen them). Still working on that one though........

Still looking for parts...
The plan is to use the Bull gear between the two transfer cases. By a little drilling we believe we can rotate the forward D20 up about 2 inches and rotate the aft D20 down about 2 inches this should provide about 4 inches of clearance for the front driveline.
The hard part if the output of the D20 is a 10 spline and the input is a 26 tooth.
The part does exist because a buddy has one for his dual Dana 20 set up. I am the expermential project going first. he has bigger fish to fry currently with installing a Ford 5.0 in his Jeep.
We will try anything once if it sounds like it will work.
As for the adaptor - I have an buddy, who is an Engineer and a great fabricator. We should be able to fashion something to work.
Just remember to do the research on what mates to what.
Current investment - Lots of time...

Ritch

shoot Rich, you should just have one EDM'ed, not that much $$ IIRC, and faster.

Take a "normal" bull gear, and see what will fit for the spline count......

I've always been curious about sharing the same
ujoint between the output yoke of one xfercase and
the input yoke of the second divorced type xfercase.
You would have to be accurate within .001" in every direction horizontally/verticaly/left/right/up/down if
you planned to drive it on the highway.
How would you align them together so ACCURATELY?

Please explain in detail.

thanks

thanks Me and a friend mounted a divorced Volvo T-case to a C**y 350TH on a SII a coupple of years ago. We went for doubble ujoints. The adapter became just short of a foot long. Only slip joint on the tranny side. Here is a low rez pic of it:
http://www.ite.mh.se/~patost/ih/ihpics/nakedfronthalf.jpg
For low speed I guess a single ujoint is OK. Maybe you could make an adapter out of a CV if you want to be able to travel faster without vibrations? Good luck anyhow.

Hmmmm,

Hadn't really thought of the problems involved with sharing just a u-joint. Went out and looked at an original F-250 with divorced case. The shaft twingst tranny and t-case is 'bout a foot long - same as my buddies modified truck.

Hmmmm,

Would a CV work for highway speeds?

Someone ought to have tryed it...

There was a guy named Spider running dual 4 speeds in his flat fender. No details. How about having a shaft machined that is equivalent to the output shaft of your trans one end and the input shaft on the other end? Assemble together. This would minimize length, give you 16 forward speeds and 4 reverse. Personally, I think this is a much better way to go than dual transfer cases. Need to get enough people interested to get a group discount on the machine work.
