Did Tera's ever have Dana 300's transfer cases? If so when?



thank you

1980 is the only year for the D300. Although you may have a swapped in unit. What side does the spedo enter the t-case? Drivers side it's a 20, pass it's a 300.

It's Terra, and 1980 was the only year and not all 80's came with them from the factory, i have owned 4 80's and only 2 had 300's from the factory. Just look at where in speedo comes in at if its on the DS=20 PS=300 and if it has alum imput and out puts its a 300.

I have read that there were a couple four cyl. three speed mans, that had a 300 attached.
I have not personally seen this, but have heard others.


I have both the 300 and 20's/ The Dana 300 has a lower gear combo, but is weaker over all. The Dana 20 is everywhere if you need a spare. But I have never broke a 20, not saying it cant be done, if you break a 20, the 300 was broke a long time ago....

Go atlas........



Later...

Other than the 4 mounting bolts or alum output housings, why is the 300 weaker..?

Out put shaft is smaller...

There is an after market replacement system that you can get that has a larger output shaft, and new bearing.

I believe you also need a new gear as well.
Would seem silly to make a step in the shaft. But there again, I have now seen it either...

Late,...

Are you saying the stock output shaft on the 300 is smaller in diameter than the 20?

Yes, the output shaft is smaller on the 300, and it has a aluminum cover... Some aftermarket companies offer a larger shaft diameter of 1-3/8" over the original 1-1/8" offers a 50% increase in strength
Later.....

What's the diameter of the 20 shaft?

I'v seen both broken. Dont be scared run um till they brake. All 1980 came with 300, even a few late 1979 came with a 300. If it had a 20 and was in a 1980 somebody swaped it out.

Both have upgrade outputs available.

Dude...Listen.

Everyone here knows about the rear output shaft upgrades, I have one I'm installing right now, this is old news. Jb has one for the front and Novak is working on one for the front output too.

My original question was something like this:

You insinuated that the 300 shaft is weaker than the 20.
If so, what is the diameter of the D20 output shaft and why is the D300 output shaft weaker than the D20?. Remember, I am not comparing Tera or AA to Spicer, just Spicer to Spicer.

So ya got it, ya bastard

The one time I didn't get the shaft, I wanted it....:eek:

Maybe I should use a single speed TC, they're real strong :flipoff2:

I have ignored this long enough..

It is true, the Dana 20 and 300 may have the same Diameter shafts. This is why the Dana 20 is stronger than the 300.

With the increased gearing of the 300, (torque) the Dana 300 would require larger diameter shaft to maintain equal strength to the Dana 20.
Dana 20 has a 2.03 to 1, and the Dana 300 has a 2.62 to 1 and aluminum tail cover.

How much larger diameter would the shaft need to be with the Dana 300 to equal the Dana 20?

It is true, you can and will break an out put shaft on a ten spline 20 or the fine-splined Dana 20 (26 splines in either case)Wich is stronger than the ten spline. So you could imagine, if you put an upgrade shaft in the 20, you would still be stronger than the 300 if the shafts were the same diameter.

So if you put an upgrade output shaft in a Dana 20 case, then you got some strength.

Neps and Joe V, you should do the math before you making your self’s look foolish.

I feel the NP 205 is even stronger, the one on the floor is only 1.96 to 1 ….

No matter how strong and bullet proof we make our rigs, we will always find a weak part…. Hmmm just to add, we run 460s in front of Dana 20s, this go around we found the transmission to be the weaker link. Ordering an adapter Monday, going C-6 this time.


Save you money and go ATLAS.

Later all

Remember, we said Weaker.......

Okay...I get it now.

What are you talking about ? I wasn't even replying to your dumb ass post :flipoff2:

Oh we're in trouble now Joe. He's been on the BB again doing some figgering. And we not bees smarte enough to be nowing them stuff likes he :flipoff2:

Would seem silly to make a step in the shaft. But there again, I have now seen it either
Please come back and play when you have somthing to tell us we don't already know. Maybe when you have actually (now?) seen one.



Yes, the output shaft is smaller on the 300 It is true, the Dana 20 and 300 may have the same Diameter shafts
Now who looks foolish ????
:flipoff:

Hmmm seems Nebs cant direct his answers to any one before he uploads.

What are you talking about ? I wasn't even replying to your dumb ass post

When he does direct them they are kind of Rude.. In fact they are rude even when not directed.

Wonder if he can actually say something knowledgeable?

Wonder if Nebs could measure an output shaft for us, since he may have the broken one...


I never stocked one back home, but then again, we was just country folk.. I truly do not remember stocking one at my Granddads IH dealership.

Besides, why would you buy a new shaft, when there are so many complete transfer cases available? Just don’t put another ten spline back in if you had one..

If you upgrade a Dana, you would have a good part of your ATLAS paid for.


Get an ATLAS....


Sorry I bored you....


I realy do not have time for childish games like this..

hmmm, looks like a post from Neps to Joe, they seem to know each other, Nebs is jealous Joe got the up grade kit and is installing it.

As for the single speed..... Neps, I'll be GLAD to trade you STRAIT ACROSS a D300 for this single speed I got here.... I know, I'm getting the short end of the stick here... but it seems to me that you can get much more satisfactory use out of it that I.... I'll even pay shipping (now how can you turn THAT down!!!!)


:flipoff2:






IH, get your panties down out of your ass and learn that sharing knowledge is very welcome here, coming off as a know it all isn't. I too was confused as hell about your "the D300 is weaker" until you mentioned the torque/multiplication issue. Now it makes sense.


Loosely translated, MATERIALISTICALLY the two are the same, however, because of the added multiplication of the D300, the output is effectively weaker....


Don't see what the aluminum output housing has to do with any of that... and you keep mentioning it. Never heard of a housing failure.


As for an Atlas, when I start busting D20's and D300 every trip... then I will THINK about one..... but since I have never hurt one of either...... I know guys with MUCH more built rigs than I, 40" tired, competition Rock Crawlers... and they run Dana's.... and don't break them *that* often....







O look, you've made me go off on a rant.... and I don't like doing that.....


so here's a Pirate salute to you :flipoff2:

may everyone have a nice day :)

IH Scout II -
Glad to see you selling all your IH stuff, could also you change your name and stay the fauk off this forum :flipoff2:

Was I rude? I'm so sorry I hurt you little feelings, maybe you can talk about it tonight at the :rainbow: support group. Group Hugs...

For a guy that's signature is "Get an Atlas" Why are you running D20 behind 460 Fords? Seems strange.

OH yea it's Neps, dumbass :flipoff2:

RustoleumWhite -

Actually I was not serious about the single speed (hence the flipoff). I've read several posts (elsewhere) about the strength of the single speed transfercase and they had about as much supporting data as IH first posted about his opinion of the D300. I figured that unsupported claims were the norm in this thread?
I guess the mud runners like them for the boggs down south, but not me...

Have a wonderful week :D

I think I'll go blow some shit up, I love my job....:nuke:

I knew you weren't serious, hence my :flipoff2:



but how can you pass up a deal like this!!! :D

Hey Nubs,, can you add?
If one does have the ability to break a Dana 20 T-case, they should get an atlas. Now as far as me saying to get an atlas, I feel if you can break a 20 once, you are going to break it twice. It makes you feel real bad when you spend allot of money worthlessly.

The way I see it, you need to grow the F>>> up...

I personally have never broken a Dana 20. or a Dana 300.

As far as selling my IH stuff, that has nothing to do with my abilities, it has only to do with the fact I am tired of paying storage on all my spare scout parts that I may need one day, and it makes no business sense to not sell your product. I have to admit, scout people are reluctant to buy things. For some reason current scout owners feel they can find it cheaper, or make it better than any one else. Go figure……

I also do not care what YOUR personal preferences are. Just to let you know, I am happily married and I hope I did not lead you on in any way.

My opinions again, if you are going to spend money, spend it wisely.

So Nubs, have you actually tried to help with some knowledgeable information, or are you here to just argue?

Oh by the way Nubs, I just got off the phone with Advanced Adapters, real nice people, (Thanks Rob) His books show the shafts to be the same diameter. 1.125.
With the increased torque, this still makes the 300 weaker. Just as long as we compare apples to apples.
No ten spline shafts in my box.

The replacements out put shafts are the same diameter as the NP 205 gearbox, and the same diameter as the OH<<<< ATLAS….

And if I wanted a bulletproof t-case, I would seriously look at the ATLAS.


Later….

You guys belong on Jerry Springer.:crybaby2:

All 1980 Scouts did NOT have Dana 300's. The early 1980's still had the Dana 20. No 79 Scouts had Dana 300's.
Also the aluminum tailshaft housing is the weak link in the 300's design. There are companies making stronger alloy housing that will not break as easily as the factory. The Dana 20 is all cast iron, which everybody knows is stronger than aluminum.
You can get low gears for the 20 and the 300, so why blow 2K because it says ATLAS. Tera-low makes a 3.15 gearset for the 20 which I guarantee ain't nowhere close to the price of the Atlas
