Topic: Dual with your chain drive

[lucky7]

Just wondering if anybody has ran duals and used thier chain drive.Wondering about the set up just got a new tranny and thinking of dualing it with the chain but it's forward shift and i'm kinda confused wich i'm sure someone can explain.

[79coyotefrg]

talk to Blackdog,  hes been running this setup for a year or two

[lucky7 [OP]]

Cool i'm sure he'll post something up 8)

what transmission/transfer case do you have? 

the t-case attached to the R150 5spd found in v6 toyota pickups isn't a forward shift.

The MC10 is designed for this transmission/transfercase combo.  It uses a gear driven crawl box, and then the MC10 mates the crawl box to the chain drive t-case. 

Its a great setup, I really like it, and it has a lower ratio than two stock gear drive t-cases.

Mines an auto, but i have an 3.0 plate with 4-7 case. Just bought anew tranny and thinking dual's to gey stock low but t-case is forward shift an unusual situation thanks

I don't believe you can split the auto from the t-case at this time.  They share the same fluid, its a whole different beast than most of toyota's setups.  Inchworm MAY have a setup for it, but I don't think so.  The MC10 will not work for your appliction, unless the new tranny is a 5spd

Is the chain drive on the 5 speed chains top or forward shift

[BLACKDOG]

Is the chain drive on the 5 speed chains top or forward shift

top shift.  But that isn't the real issue.  Due to the way the auto tranny and transfer case were designed, they can't be run seperated (as far as I know)  they share fluid, and I believe that some of their components also share housings, but I'm not entirely sure.

The Auto tranny on the 3.0 has a automatic transfer case with its own valve body and clutches which cannot be dualed
I just finished a conversion with an inchworm adapter and swapped in a gear drive case with Marlin 4.70 gears

I was looking here to see what it would take to do a crawler in my T100 auto.
It's a foward shift chain drive "righty" with a 23 spline output , but the case is exactlly like a Taco trans.

You just need a 3.0 adapter and your good i run a 4.7 gear case just thinking of duals going to see marlin monday.

[Jomentum]

That's where things got mixed and matched on the T100:

 3.4 v6 with the a340f trans (same as Taco) but ,with 23 spline output...
Chain drive "righty" forward shift (no other vehicle)manual T case

Nice that's what i'm talking about

[BLACKDOG]

You just need a 3.0 adapter and your good i run a 4.7 gear case just thinking of duals going to see marlin monday.

wait, what?  you already have a 4.7 gear drive case in there?  I'm confused now

[lucky7 [OP]]

No thats my current set up ,bought a new tranny with t-case and thinking about dualing it .

[79coyotefrg]

im so confused

[BLACKDOG]

No thats my current set up ,bought a new tranny with t-case and thinking about dualing it .

what do you have right now?  a 5speed with the 4.7s in a gear drive t-case and a 3.0 adapter plate?

why did you get a new tranny?  you're going from a 5speed to an auto? 


We need a little more information from you, you aren't being very clear on what you have, what you bought, and what you want to do. 

IF you already have a 5spd, with a 3.0 adapter plate, and the gear drive t-case, I'd either run the 4.7s in the crawl box, and buy an MC10, and obtain a chain drive tcase.  Or, just buy an MC07, and run 2 gear drive t-cases.

just an FYI, I've never personally wheeled with one, but the autos I've seen people use for crawling have not been up to the tast.  They over heat fairly quickly, and start slipping in a short amount of time.  Just an FYI from my experience.

I'm running an auto with 3.0 adapter and a 4.7 gear case but the new auto i just bought has the chain case thats forward shift. So i'm thinking of combining them with the 4.7 as my front case  but i didn't think i could use the forward shift in the chain

[UKMyers]

The MC10 came out about a month after I bought a ready to run 23 spline dual ultimate.......glad to hear it's working out for people.

[BigMike]

lucky7 already has a T100 auto trans in his 4Runner with a 30-4GT adapter plate to a single gear drive t/case with 4.70:1 gears.

lucky7: You need to check if your new auto & t/case has a 9-bolt divorceable t/case.

In such case, all you need is another donor gear drive t/case for use to assemble a MC07-generation Crawl Box (or a billet MC08-generation).

The MC10 would not be good for you since you already have a 4.70:1 gear drive t/case. The MC10 allows a right-hand chain drive t/case to be mounted behind a gear drive reduction housing. Therefore, only use the MC10 if you plan on also using a stock chain drive t/case.

If you want to go duals with a gear drive 2.28:1 Crawl Box in front of your 4.70:1 gear drive T/case, then you need the MC07- or MC08-type adapter.

I have seemed to confuse everyone mine's a t-100 right side drop already have an 3.0 adapter just want to know if i can put a forward shift chain drive t-case and make my 4.7 case my crawl box

[Jomentum]

I'm thinking the Same thing with the stock T100 transfer.

 1. Its a righty
 2. modify the shift rails to make it a top shift ?
 3. add the doubler ?
 4. or = adapter, doubler ,23 spline ,1 gear tcase with 4.7's, do the second tcase stock

[lucky7 [OP]]

Yep gonna go see marlin tommorow

[lucky7 [OP]]

Marlin hasn't done this so i'm thinking now of a 2.28 forward shift t-case and rotated adapter forgot to ask about that. Not sure if the shifter block is right apreciate some input

[Joey88RUNR]

So did you figure it out? .....i Got my motor running lets go wheelin

[lucky7 [OP]]

Next weekend tranny is in got a couple of bugs should be good tommorow
