Why you cant rebuild your AE86 T50 with TE72 internals Fri, 07 January 2005 04:32 Go to next message
Now I assume everyone knows the external differences between AE86 T50s and TE72 T50s (input shaft bearing, bellhousings wont swap, output spline number).

Given I have a AE86 box with teeth off second gear and a really good TE72 box lying around I decided to strip them both and rebuild the AE86 box with the good internals.

There are a few minor internal differences, but nothing seemed insurmountable until I found two things:

- The hole in the TE72 5th gear is smaller than the AE86 output shaft and so wont fit on the right spot. Quick solution, use the AE86 5th gear.

- The hole in the centre of the TE72 second gear is about 1mm larger in diamter than the corresponding place on the AE86 output shaft, meaning it'd slap around.

Since my AE86 2nd gear is rooted the project ended there. Everything else seems possible to switch over.

Henn,




You would seem to have an early TE72 Box.


According to my info the TE72 between 8106 - 8305 is exactly the same part Number for the 2nd Gear.



Failing that - you could always donate the AE86 Box to me Laughing Laughing Laughing

That's very interesting, unlucky I had the old box.

And yes, I now have the entirity of both boxes sitting around in very neatly labelled sandwich bags, so if anyone could use bits please PM me.

hmm shame your so far away, ive got two boxes here that ive been planning to do the same test project on but havent pulled finger and stripped them to check if the ratios will interchange. been meaning to go get some syncros and start the rebuild for 12 months Smile

Any chance you could take some pics??

im trying to do mine opposite to you, take the AE86 internals and swap them into the TE as I have a good AE box and a slowly dying TE

Hmmm, I've got a TE71 2TG box that's in good order, and an AE71 box in my KE70 that's gradually not liking my treatment. I'll be interested to know the possibilities!
