Identify the calliper and diff!

[brett_celicacoupe]

if your still stuck on finding out what diff it is, measure the PCD of the diff centre carrier mounting bolts (those 10 or so bolts in a circle). IIRC correctly, the PCD is bigger on the F series compared to the T series. you might need some tricky vernier callipers with real long jaws to do it accurately though

this might sound really odd... but... the diff or alteast the axle and diff housing isnt the origianl that came with the car... the AE86 written on them screams wreckers.. and given they have that written on it there is a reasnable bet thats what its come from originally... id be looking towards the obvious.. ie: t series diff but possibly other brakes ? or even the t series brakes but the photos are from the wrong angle etc so ppl are misdiagnosing them ?

just a thought.

TooF: Aus AE86s didnt come with LSDs and disc rear ends. It is fairly obvious that a JDM AE86 rear end has been swapped in.

The calipers you have there are stock AE86 JDM calipers, nothing special about them whatsoever. Seems that there may be multiple different calipers for the diff, but these are definately your run of the mill calipers. I have them on my diff, and they are on the other 3 diffs in the workshop.

I can definitively say that what you have is an AE86 JDM diff, with the stock JDM discs and calipers.

EDIT: ill even post pics of my calipers tomorrow if i remember to bring the camera home from the shop.

[TooF]

i know they didnt come hjere with discs or lsd.. but given the writing on them there is a decent chance that the diff originally was from AN ae86. so the odds are that it would be a jdm disc/lsd item from an ae86 originally...


all im saying is that i wouldnt go looking at the possibility of it having been swapped from another type of vehicle when it seems there is a fairly good chance its from a ae86.

[takai]

Yes, i understand what you mean. But that was ascertained towards the top where they were debating the T/F series long bolt prospect.

I also have exactly the same brakes on my disc rear end about to put into my AE86 . It also is LSD.

The handbrake cable part numbers are
from toyota

46430-12200 and 46430-12300, about $86 each i think.

I have a secondhand set if interested pm me.

[slide86]

cheers for all the positive feedback guys.

i think we have finally decided what the rear end is. i am keen to go with the JDM option.

i also noticed the wrecker writing on the housing, this lead me to believe that its a genuine change over.

thanks to all.

Measure the disc. It might be an MA45 t series, they have a larger disc than the 86 (265mm ish?)

I compared it again today, it is definately a stocker JDM T-series.
wraith, consider other things such as the trailing arm setups, it would NOT be a bolt in if i was a MA45, and wouldnt be marked with AE86 if it was.
The discs certainly much larger than 265mm, if anything i would say 270mm max.

[wraith]

I'll be damned. That MA45 diff I drove around with didn't actually fit eh? Must have done 15,000 odd kms on a diff that didn't actually bolt in! I'm still going with my original theory...

cheers

Ash

btw- is the handbrake on a screw lever? ie, in the caliper, not an internal drum.

[takai]

Well, i would say that you are wrong. Because this is a JDM AE86 LSD diff right here:

As seen in the arse end of my race car. Those calipers are definately AE86 as well, as the Endless pads which they came fitted with were marked with the AE86 part number. The handbrake is a screw type as well.

Always remember that your coveted MA45 discs may be fitted to the AE86 diffs as well. But that is certainly an AE86 diff.

[wraith]

I wonder if MA45 calipers are the same as '86 ones? Just running a larger disc? The only reason I was thinking down that line was that your discs seem somewhat larger than stock JDM rotors. Like you say, it's possible its a MA brake setup on an '86 / T-18 / whatever T series.

Ash

[takai]

Well thats all up to the caliper bracket. But i cant see why it would make a difference, the pad diameter doesnt change at all, and the main reason to increase the hat diameter is to incorporate an internal drum handbrake. Which the MA45 doesnt have from what i gather.

The discs there are exactly the same as every single other T-series disc rear end which is in the shop at the moment. Same as about 4 others, as well as one with new discs. So they are no larger.

Ah, that's the crux of the issue then. I was under the impression that the discs were larger than stock JDM AE-86.

[Toy_T-18]

well for starters is say AE86 on the diff in chalk, yeh that may not mean much, it may be a T series diff out of a T-18, with mitsubishi sigma disc's or with R31 skyline rear disc's, and if u want a LSD to go in the T series diff, the Hylux LSD goes in so i have bin told but i could be wrong!
