custom axle info and identity help


Recommended Posts

trying to fit a 5 speed into my 86 brat. the 5 speed that i have has 27 splines on the front transaxle. It is also 10 inches shorter than the original 4speed. I know that the tranny came from a turbo car but i am not sure what year. the cv that fits the turbo tranny was to long and the seal ridge? was to big for the brats wheel hub if anyone knows how to id this tranny and the car that it originated from that would be a great help also need to know where to get custom cv made or ordered.

Sounds like the tranny came from an EA82 turbo model. That means its axles are 25spline and it's also longer than your EA81 axle. Life would be much easier for you with a 5MT out of a non-turbo vehicle. Then you'll have the same 23spline all around (so you can reuse your old axles)

 

If you must make it work then it's time for some custom axles. You'll need to take your old EA81 axles and take off the inner DOJs. Then put the DOJs off the EA82t onto your EA81 shaft. However now everytime you need a new axle you'll have to do this.

27 splines counted them several times also the diameter of the turbo axles was thicker so you just cant switch the DOJs. (what does that stand for)

Double Offset Joint; the joint that connects to the tranny.

 

I was always told that EA82t axles were 25spline. Never heard of a 27spline axle. Maybe it's not out of an EA82 then; maybe it's out of an even newer Subaru?

 

Can you contact whoever you got the tranny from? Surely they have some info on what it came out of.

If it was a hi/lo speed turbo car, most likely it was an RX. In which case, morgans first advice applies.

 

There are no 27 spline old school transmissions. If it is an old school (pre legacy) subaru transmission, it will be either 23 spline( non turbo) or 25 spline (turbo)..

 

Referring to manual trasnmissions only

lets say for argument sake that i cant count and it is 25 spline. the turbo axle that i had was a thicker shaft so the inner doj off the turbo would not fit on the old axles. is there a way to change out the outer doj?

Take the DOJs off both axles and sneak a peak. Maybe the end of the axle shaft is machined down on that phat Turbo axle to fit into the DOJ? Suposidly there is a snap ring holding it on. I've always just... beat it off!

 

We'll get something figured out :)

yes, there is some machining involved. a couple of board members have a turbo tranny in a ea81 based vehicle, and have had to have custom axles made...

Ill sell you my custom axles with 0 miles on them but they have been installed. I paid $120 a piece for em i want 100 each for em and you can keep your cores I won't need em. Im going to rebuild my transmission and switch the stubs out so I can run standard axles.

 

These were built by CV Of Ocala.
