T-18 info

[ksouthw80]

Hello All

Someone is selling a T-18 with a Dana 20 Tcase in my area,
it needs a rebuild, which I can handle. Says its Jeep fs-j 4.02:1 first gear. Says will fit a J10. I'm not familiar with the J10. Is this the model I need for a CJ7 AMC304? I'm stuck at work, can't research, barely had time to type this out. Any info is greatly appreciated.

currently model 30/ 20 axles. Plan to change anyway if this helps

According to Novak, the Ford version is a much better and more straightforward option...Jeep models present a multitude of issues:

Okay thanks. I read the article. Not the one.

Good find, but a J (truck) series T-18 has a long input shaft - you will need to change it.

Everything is the same (Dana 20 .) It's a bolt in.

As for the ford T-18 , they require an adapter plate but do work with a CJ.

Either way you will need new or modified drive shafts.

It's advertised with adapter plates?????? ( I know there are many different set ups). This guy also has a CJ5 for sale. He probably realized the T-18 wasnt the desired one after purchasing it. I dont know. But I feel I should wait and hopefully find the 6.32 gearing.. You agree?

$100 dollars for the set up

If you plan on doing any serious off roading, wait until you find a 6.32. You will be much happier with the granny low. I had a J truck T-18 in a CJ7 . It used a 5" adapter to allow for the long input shaft. Also had a really short rear driveshaft! I have since replaced it with a CJ T-18 . Picked one up with the 6.32 and a Dana 20 Transfer Case , both in great condition for $500.

I *think* you can use the main shaft and adapter on a Ford T-18 . For $100, It'd be a cheap adapter. But you'll need to do some research to be sure.

Thank you for the replies.

For $100, you would be getting two parts necessary for converting a Ford T-18 to work with the Dana 20 . Those would be the main shaft and the output gear. You will need to purchase an adapter plate, but that should be way less than the cost of a complete kit.

When I did my Ford T-18 conversion, I gutted my CJ5 's T-18 (4.03 1st) for the main shaft and the output gear. The 'Texas Pattern' adapter plate (cast iron) on the Jeep T-18 would not bolt directly to the Ford T-18 . It's been a while, so I don't recall what or how it didn't match up. I purchased the adapter from Parts Mike. It was the version made by Advance Adapter in aluminum.

The Ford T-18 has the 'butterfly' bellhousing bolt pattern. This will work on a Jeep CJ bellhousing for a T-176 . Not certain about working on the T-150 , as I'm not familiar with that one. Since my resto-mod CJ5 has a Ford 5.0L, I used the stock Ford bellhousing. Adapting to an AMC engine will require a special pilot bearing, IIRC.

I've had a few minutes to look into this conversion. You make a good point. I'm leaning towards purchasing this even if it sits in the mean time. To help fund the conversion I could sale my rebuilt T-150 . Clean up and twin stick the Dana 20 with teralow gears and sale that one. The one I have now is already done that way. After doing it once I could rebuild the Dana 20 in short time. Bead blasting and cleaning/prepping is the worst part.

Thanks for the input.
