Does anyone know of the interchangeability of the Scout dana 20 from the T-18 i think, to the Jeep T-150. My friend has a scout dana 20, they are the same side diff drop, but what about the bolt pattern and the input shaft size??

They are exactly the same. I like the Scout 20 better because the shift tower on it make it easier to twin stick than the Jeep version.

The scout has a texas style pattern that differs from the jeep.

Ok, one person says they are exactly the same, and another says different bolt pattern...

CSP is wrong. The bolt patterns are different, as are the shifters.


It's just like the Scout 727 vs the Jeep 727. Internals are swappable, but they don't bolt up the same.

The jeep also has a texas style pattern. I didnt look too close at the scout 20/18 and the jeep 20/18 right next to eachother. But all the bolts appear to be in the same spots.

Agree with Mike if you are swapping Heep and IH 20's then the pattern is the same. 18's have large and small bore's. IH 300's use Texas pattern, heep 300 round pattern

If they weren' the same how do Jeep guys steal our D300s??????

Good point Bob.

Actually, the Jeep 20, like the waggy 44, is a more modern transfercase than it's scout sibiling.

NQs

That's just because the jeep 20 is more aerodynamic cause it wasnt designed for farm equipment

Can't forget the molecular decay is slower for the heep stuff

Bullshit if I am wrong! The Jeep Dana 20 and Scout Dana 20 (and 300) both use the Texas pattern. Now a Jeep Dana 300 does have a different pattern and won't bolt up. We're not talking Jeep 300's though are we? The guy asked about using a Scout 20 behind a Jeep T150. The Jeep T150 was only used with the Dana 20 tcase behind it, so that eliminates comparing a Scout 20 to a Jeep 300.

I already mentioned that the shifter towers are different. That has nothing to do with the two being interchangable with each other. I have a Scout Dana 20 bolted to the back of my T18a where a Jeep Dana 20 was. No mods required!

BTW, a Jeep 20 will bolt to a Scout 727 with a different bull gear used in the tcase.

Yea what CSP said is correct....

I've got one of each right here :D

So the consensus is that i can buy my friends Scout dana 20 because it WILL fit the Jeep T-150 that my Jeep dana 20 is behind right now??

I will add I have a Scout 20 bolted to a Jeep TH400 factory model 20 adapter laying in my iron pile now...so they must be the same huh?

NoRM

And I have a jeep 20 bolted up to a th-400 using the factory adapter. So I would say they are swapable.

I even have a scout 20 bolted to my Ford T-18 using a Jeep Dana 20 adapter, hows that for cross reference.

OK, now i got a new question, i want to use the TF 727 behind my 85 wagoneer in the jeep. I want to mount a dana 20 to the 727. What dana 20 do i need (scout or jeep) and what would i need to make the conversion work?(or can it work) i read that the jeep 727 has a 23 spline output and the t-150 has a 6 spline output. will any dana 20 work??

What you need is the tail housing, output shaft, and bull gear from a Scout 727. I'll sell you the one I have or swap the parts. I have one pulled and ready to go. BTW, I'd recommend keeping the parts for future swaps, but I'll gladly trade you.

As far as the case goes as long as the t-case is from a Scout II, or from a 70's jeep you'll be ok. Dana used two pitches on the gears in the 20's 17 and 20 degrees. The newer t-cases tend to use the 17 degree pitch. You can pull the numbers from the cluster gear to determine if the two are compatible.

Fawk the D20! A jeep D300 will bolt right up. Plus it's a better case!

well i want to change engine/tranny in jeep but iw ant to keep the 20 cuz i got it, and the driveshafts are right, etc.

Dude to get the D20 on the end of your 727 your going to need to change out the tailshaft/housing of your trans. That requires a complete re-build and the the length on the trans will change because of the new tailhousing. Your much better off dumping the d20 turd and getting a d300. There is little difference between the size of the D20 and the D300, I would bet your shafts will work.

I took photos of my T-18, T-150, and Ford FMX auto trans to Dana 20 transfer cases. They look identical to me as far as mounting is concerned.

Sweet. It only took you 6 years to solve his problem.

With all you extra free time you can finally get started on that national debt problem.:shaking::shaking:

:lmao::lmao::lmao:

I knew it was old because old scout was actively posting!
