Hey guys, I heed a little help here.
I'm about to order new Tilton clutchplates for my MFR tranny.

As the thread title says: what is the axle diameter and spline count?.

Measuring my allignment tool its, 23mm and 22splines. Only problem is that i can't seem to find that size anywhere.

Its a dual 7 1/4" assembly.

Thanks

Nevermind, I actually went and measured the axle on the gearbox, its 24mm with 22 teeths/splines

 

Bump .

Today I recieved an e-mail from Tilton, they claim that Rx-7 shaft size is 1" x 22 splines,

Someone please confirm this!!!

 

Same input shaft size as an FC turbo / FD?
It should be 1" x 23.

^^ K thanks, but I guess that Turbo and FD's has one more spline than 'NA's.
I counted several times, its 22.

 

Non-turbo uses 1" x 22 clutches, Turbo II and FD uses 1" x 23 clutches.

 

You sure about the non-turbo part?
I swear it was 7/8".

Nearly, actually it's 15/16" ( just fitted one this week to my 1st gen).

^^ hmm thats odd, the 1" I bought was a pretty snug fit, could hardly get it on the shaft.
