T18/T98 adapter

Do they use the same Tcase adapter? If so would one off a T18/D20 work for the T98/D18??

 

I can take a pic of my adapter if that will help.

 

If you could that would be great.

 

Yes.

I have pics of all the adapters ,and the nose cone Ill post them tonite when I get home . maybe it will help finding the right stuff.

 

Hi all,
One thing to watch for between the t18 and t98 adapters is diameter of the pilot register that indexes the adapters to the bore of the transfercases. I have a t98 adapter here made for the small hole Spicer 18 transfer case, I also have had t-18 adapters with a larger pilot for the late spicer 18s and dana 20 transfer cases. Also, even though the adapters may interchange somewhat, keep in mind that the mainshafts are different, since the t-98s use loose rollers under second gear and have a different size pilot diameter where they mate with the input shaft, if I remember correctly. If you are going to switch mainshafts between cases, I am pretty sure that the corresponding gear sets have to be switched as well. Hope this helps!

Good info and you're correct. You can put the T-98 guts in a T-18 case and vice/verse but you must change ALL the gears and shafts. Nickmil.

 

Heh, heh, heh, you've got a T-18 because the cases are the same for early T-18's and T-98's (Jeep applications). I've seen factory T-18's that had factory T-98 tops on them (earlier version with reverse over and towards the dash). Either that or it's a red-headed stepchildR) Nickmil.
