I am collecting pieces and preparing to swap a t-18 4 speed into my jeep. My jeep isnt exactly stock but I built my engine adapter to mimic an l-134 and it has a t-90 in it now so the procedure would be the basically same for a stock 2a. Ive been chatting with a few people that have done this.... I'm trying to keep it as simple and reliable/durable as possible. I know the t98 would be easier but I have the t-18 and t-98's are getting hard to find. Im sure some of you will think im crazy.....and you're probably right! haha! I have had this t-18 sitting in a corner of my dads garage since I was about 17.....it was waiting patiently for me all these years. Now is the time! This was a 2wd version from a 78 ford T-tag truck. I paid $125 for it back then. I bough it to steal the short ford input shaft so I could put that in my cj5. So I stuck the long Cherokee shaft back in it and havent touched it since. This is the 6.34 first gear model. I pulled the top off and it looks pretty good! So I still need the correct input shaft to work with the jeep. So I found a good used original Borg Warner ford input shaft on ebay for $45. They wrapped it up really well! It looks good. So the first challenge here will be the shaft diameter. The willys has a 15/16 10-spline..... the ford is 1-1/16 10-spline. Willys is 7" stick out the ford is roughly 6.5" I have a few different ideas. I can turn the ford shaft down to 15/16" and cut the splines a little deeper. Or, I can leave the shaft the way it is and run a clutch disc from an 81 ford 2.3L. They are 8.5" diameter and have a 1-1/16 10 spline hub. Then comes the issue of the bearing retainer. I'm still working on that. Ive seen people make a spacer that allows use of the t-90 retainer and throw out setup. Or I may end up making one from scratch. The other thing I needed was a mainshaft and a transfer case adapter. The jeep Gods smiled upon me .....I picked this up today on craigslist for $150! I was thrilled. This is a 4:1 ratio T-18 so I wont use it for anything other than parts.. and it came with a good dana20. So, i have my main shaft and transfer case adapter. This one also looked decent inside and had a strange coating in the case. Transfer case appears to had had the seals replaced not long ago. I haven't gotten too far with this yet.... Ive been busy working on the roll cage. Im just collecting parts and doing research as I clean up the parts i have and order things little by little. The plan is to have this setup completely ready to drop in before I tear my jeep apart. I dont want it to be off the road and more than necessary. Updates to come.
