S and T series diff info

[slide86]

to prevent people asking same questions all the time. if you know more stuff add it up. definate stuff too, i know some celica diffs will fit but there are differences that i don't know of for sure so i haven't put them in.

S Series = ADM = no LSD available
T Series = JDM or T18 + others = plenty of LSD's available (KAAZ, Cusco, TRD etc)

S Series 8 bolts carrier to axle housing
T Series 10 bolts carrier to axle housing

S series = ADM AE86
T series = JDM AE86, T18

when fitting a T series diff you need a shorter rear tail shaft either out of a JDM 86 or a T18. the rear shaft for a t series is 20mm shorter than that of an s series


ADM AE86 760mm, T18 740mm

Ke70's have a borgwarner diff different to S and T series. both S and T series will bolt in but an s or t series tailshaft must be used.

tailshaft and diff combo's (assuming you have fitted 4AC or 4AGE and using T50 box)

AE86 + T series = ADM or JDM front half + T18 or JDM rear half
KE70 + S series = ADM 86 or JDM 86 front half + ADM 86 rear half
KE70 + T series = same as AE86 with T series
AE71 + S series = same as KE70 with S series
AE71 + T sereis = same as AE86 with T series

LSD Fitment

Borg-Warner: No LSD's Available

S-Series: No LSD's Available (although extremely rare factory ones are rumored)

T-Series (all versions): LSD's Available from the factory, Commonly Available aftermarket (KAAZ, Cusco, TRD etc)

F and G series: LSD's Available from the factory, some aftermarket LSD's available

E-Series have no LSD's available.

Different versions of the 'T-Series'


JDM 'Kouki' (late model) T-Series:

Slightly thicker axles compared to Zenki / ADM t-series (1~1.5mm)

Larger bearings compared to Zenki / ADM t-series

Disc Brake only (reference required)

1410mm Width

Mounts will line up to any xE7x / AE86

JDM 'Zenki'(early model) T-Series

Slightly skinnier axles compared to Kouki T-series

Smaller bearings compared to Kouki T-series

Disc OR Drum brake (Disc and drum brake have slightly different housings)

1410mm Width

Mounts will line up to any xE7x / AE86

ADM TE72 T-Series

Axles / bearings / Housing same thickness as JDM zenki drum

Drum brake only

1410mm width

Mounts will line up to any xE7x / AE86

ADM TA22 (post 73), RA23, RA28

Axle thickness same as TE72 / JDM Zenki (however they are shorter)

Drum brake only

1365mm width

Mounts will not line up properly with xE7x / AE86 mounts

ADM RA40, RA60

Axles thickness / length (splines unconfirmed) as TE72 / JDM Zenki

Drum brake only

1410mm width

there is a minor difference in the measurements of the mounting points for the trailing arms and also the spring seats are slightly smaller also but factory xE7x, AE86 springs and trailing arms still bolt directly into this diff


Suitable Toyota Differentials to transplant into your AE71 / AE86


Moderate power:

Assuming you are running a T-40 / T-50 gearbox.

T series Differential from a JDM AE86 or ADM TE72, using the following tailshaft combo:

AE86 Front

TE72 Rear OR JDM AE86 Rear

This is because the 'nose' of the carrier on a T-series is 20mm longer than that of an S-series

Large power:

E / F / G series, using a custom tailshaft + mounts


Understanding Toyota Diff Codes / List of Toyota Differentials

Toyota diff codes are broken down into several parts. As an example we'll use this one:

T292

This is then broken down into several parts, like this

T/29/2

The 1st digit denote the size of the Crownwheel

The 2nd two digits denote the ratio of the differential

The final digit denotes the number of pinion gears and if the differential is a factory Limited Slip Differential (LSD)

The 'translator' for diff codes is as follows:

First digit:

[pen15]

a quick question for u gurus can i put in an ra40 center into my t series i think its a small axle version because all the sway bar mounts are welded on if any1 has some good info ill be appreciating it alot cheers mat

[af300e]

E / F / G series: LSD's Available from the factory, some aftermarket LSD's available


E series LSD? You sure? Were 4X4 liteaces e series with LSD?

[Paoabarai]

Hilux diff. belong to which series? E, F or G?

[slide86]

hilux is G series

[Javal]

a quick question for u gurus can i put in an ra40 center into my t series i think its a small axle version because all the sway bar mounts are welded on if any1 has some good info ill be appreciating it alot cheers mat

Yes.

Use punctuation next time.

[slydar]

no e series lsd available.

actually there is some really shit old holden "cone type" lsd you can make fit. but its crap.

rear hilux diff is g (or A in later models with higher output, turbo diesel/4L ect) front is F.

also ALL t series are small axle/zenki, except later model ae86 ('85.5-87)

[YAZE]

Just quickly. The KE70 wagon and sedan, both having the borg warner, are they the same bolt pattern? So an AE71 tailshaft will bolt up in my KE70 wagon?

Cheers

Yes.

[Paoabarai]

Is there any performance lsd for the G series?

[slydar]

yes. 80 supra and other some other 1/j/2j powered cars use g series. so basically every brand does a g series lsd. but its absolute over kill really. and also a costly conversion, as you will need to change the pcd on axles. or change to 5x114.3 at the front of the car to suit. the donor diffs are also rare/expensive.

[Paoabarai]

The car i bought come with this conversion(Hilux diff) already and now looking out for G series lsd.

No, Javal is wrong (rare).

It will bolt up to your diff center yes, but the shaft from the gearbox is different. AE uses the T series gearbox and your KE wagon has a K series box.

Japanese Domestic Market (herein referred to as 'JDM') AE86 Sprinter (Kouki): T-Series (Kouki)

Japanese Domestic Market (herein referred to as 'JDM') AE86 Sprinter (Zenki): T-Series (Zenki)


Different versions of the 'T-Series'

JDM 'Kouki' (late model) T-Series:

1410mm Width

if kouki axles are 1 - 1.5mm bigger than zenki, what is the thickness of zenki axles???

or what are other ways of finding out if i have kouki or zenki

(previous owner changed diffs and cant figure what i got in my 86)

[s14seriesII]

zenki has same spline axels as s series and t 18 ra23, ra40 etc

kouki i understand is bigger, but also a quick question..

zenki disc rear end does it have double row axel/wheel bearings ?? none of the local t series do..

[slydar]

yes. all jdm ae86 disc brake diffs run that wheel bearing.

[slydar]

E / F / G series: LSD's Available from the factory, some aftermarket LSD's available

can that please be edited. its possible people will read this and buy an e series under the impression you can get an lsd for them. which is not the case.

[Cerby86]

is the diff code anywhere on the diff itself?? Or only on the firewall?

[s14seriesII]

only on the firewall... but you can tell by size and how many bolts and the lenght of the studs holding the centre in.. otherwise pull the centre out and measure the crownwheel diameter and number of teeth (sometimes stamped on the crownwheel eg: 39/10 ) and by the diametere you can tell what the code is

[hachi_dk]

yes. 80 supra and other some other 1/j/2j powered cars use g series. so basically every brand does a g series lsd. but its absolute over kill really. and also a costly conversion, as you will need to change the pcd on axles. or change to 5x114.3 at the front of the car to suit. the donor diffs are also rare/expensive.

what cars come with the diff your talking about?
80's supras?
because i need to find one thats 5 stud as your saying; as my ae's 5stud.

[s14seriesII]

the lsd hemisphere makes no difference to how many wheels studs you have it doesnt even make any difference to the diff ratio your using, but im pretty sure all vehicles fitted with a g series are either 5 or 6 stud and all the models mentioned are also irs, which again makes no difference to your car

[ke70dave]

jsut thought id let you guys know


KE70 + S series = ADM 86 or JDM 86 front half + ADM 86 rear half
KE70 + T series = same as AE86 with T series

this doesnt work with K motors. (or specifically K gearboxes, k40 or k50)

you cannot join a front K gearbox tail shaft to a rear ae86 tailshaft (S or T). and the front 86 tailshaft wont fit into a K gearbox.

86 tailshafts can be spit via a flange, but ke70 ones cant be. they can be split but its via the uni joint. so its different.

believe me i tried it. luckily i tried the tail shaft before putting the diff in!

[hachi_dk]

im just asking what diffs are 5 stud. never said anything bout the hemisphere or diff ratio

[Cerby86]

jsut thought id let you guys know


KE70 + S series = ADM 86 or JDM 86 front half + ADM 86 rear half
KE70 + T series = same as AE86 with T series

believe me i tried it. luckily i tried the tail shaft before putting the diff in!

what about ae71 tailshafts??
Are they the same as adm ae86?

[hachi_dk]

do kouki lsd's have 23/24 splines while zenki 22?

[ae86]

zenki and kouki axles/lsds have same amount of splines, its just the diamatre's are different

[ke70dave]

what about ae71 tailshafts??
Are they the same as adm ae86?

hmm im not really sure, i cant remember if it had a flange like a 86 one has.

if i remember ill have a look under my car tomorrow.

[squish_m8]

can anyone tell me what ratio s-series diff came stock in adm ae86's?

[hao.]

^ 3.9 I'm sure.

[squish_m8]

awesome. which makes it identical to the ae71 panelvan s-series... well the center anyways

[pogi]

hey guys i got a JDM zenki T series was wondering if axles are the same as an ra60 or t18 ? just want a straight in and play kinda thing

[s14seriesII]

hey guys i got a JDM zenki T series was wondering if axles are the same as an ra60 or t18 ? just want a straight in and play kinda thing

aparently all jdm diffs have double row wheel bearings.. so short answer is no they are different

[blair]

So, acording to javal theres no T series disc thats ADM?

what is it from then if it is disc, but the mounts dont line up to Sprinters?

:S

[s14seriesII]

could be a t series from, te71 sr5 ? (2tgeu) , ra23 gt , ta23 gt , ta22 gt all these are japan models with t series and disc brake

theres probably more

[nichy]

ok now i have read this.... and just confused my-self .. lol

trying to work out what tailshaft combo i need...

ke-70 sedan with a 5spd ke box (k50?) and i am puting a series 1 t-18 diff in.

do i need t-18 rear half? or what lol

any help would be great

[matt99]

Yeah pretty much.

Or a KE 70 panno tailshaft, which I just h appen to have.

$15 for it if you pick up, im in Melbourne.

[nichy]

im in hobart mate... cheers anyways...

so if i can get a t-18/ke70 pano rear part of the tail shaft i should be right ?

[nichy]

or ???

[Golberg]

ok now i have read this.... and just confused my-self .. lol

trying to work out what tailshaft combo i need...

ke-70 sedan with a 5spd ke box (k50?) and i am puting a series 1 t-18 diff in.

do i need t-18 rear half? or what lol

any help would be great

You need a complete series 1 t-18 tailshaft. Or a complete KE70 panel van shaft should do you too.

You need the whole thing, not half of either, your existing KE70 shaft is useless to you.

[nichy]

i didn't think that a t-18 shaft would go into a 4k box.... dont t-18's run t50's ?

or will it just fit lol

[Golberg]

The series 1 is important in the tailshaft, series 1 T-18s run an earlier style T50 with less splines, same as KE70 I have been repeatedly told.

Series 2 T18 on the other hand has the same T50 as an AE71 or AE86.

[nichy]

ah well thanks for clearing that up :P

cheers guys

[ae86]

anyone knows part number for T series axle seals?

[nichy]

t-18's series one run a 20 spine tail shaft same as a ke70

just for the info lol

[blair]

ADM RA40, RA60

Axles thickness / length (splines unconfirmed) as TE72 / JDM Zenki

Drum brake only

1410mm width

there is a minor difference in the measurements of the mounting points for the trailing arms and also the spring seats are slightly smaller also but factory xE7x, AE86 springs and trailing arms still bolt directly into this diff



I'd like to queery this... i have what i beleive to be an RA60 Diff, and yes the trailing arms are off by a bit, and the spring seats are smaller. However they are MUCH smaller, to the point i do not see it safe to use AE86 Springs. Mine is also 1430mm, about 10mm Wider each side than AE86! Do i have a different differential than thought??

:(

:(

well i know for a fact that ra40 uses the same t series centre and axel splines but its 1430~1440 mm wide and spring seats are very close to ae86 (close enoguh not to worry about) so if you are sure its a t series it could well be the ra60 diff...

[Jacobxxx]

anyone know specs on ra60 diffs?

[blair]

Yep refer to your other thread...

[CoR*]

Ok so im getting hold of a t series from a TA22 to put in my adm 86...
Ive read that the axles are shorter in TA22's??? Think if i got zenki ae86 axles... and transplanted my mounts / trailing arms from my s series would that work?

[Hachi_Tom]

what defines "high power", as in how much can a t series handle....

also, what brakes, the axles? surely cant strip the teeth of the crown wheel and pinion..?

[blair]

T series can handle exactly 121.333086772 kw's... PSYCH...

Just look at how small the diff is, and compare it to a diff that the motor your putting in would typically match up with, and if there isn't one because your engine is heavily modified then just put the biggest one you can find in.

[sld sho]

ok so ive got a 4ac, t50, dnt no what tail shaft, and just got a t18 drum to drum diff, what tail shaft will i need?

[Javal]

ok so ive got a 4ac, t50, dnt no what tail shaft, and just got a t18 drum to drum diff, what tail shaft will i need?

AE86 Front half TE72 rear half

or full JDM AE86 tailshaft.

[44GTE]

AE86 Front half TE72 rear half

or full JDM AE86 tailshaft.

Correct
'
And i have full JDM AE86 front & rear if you need

cheers

[mikare]

Can anyone post the pictures of the carriers of the S, T, and F series differentials.

[sld sho]

hey guys i put the t series diff in to my ke70, the diff has ra60 brakes, and the handbrake cabel isnt long enuff? any ideas?

[blair]

use the hand brake cable for the car, not the diff. the cable length for the most part is determined by where the cable runs. Thats what worked for me anyway lolz

[raceAE86]

Very informative fella's, good job.

Not E7 or 86 related but for all of you who have a cressida they have a G series diff, FTW.

My 2 cents.

[JAM533]

if kouki is larger then zenki by 1-1.5mm than what is the actual diameter of each?
trying to figure out what iv got haha pulling it out tomorrow to measure it so i can hook up an lsd centre

[JAM533]

ok measured my axle's today, diameter of 23.8mm, so from what i know this is zenki. if someone can confirm this it'd be a huge help =)

[Turkish-86]

what defines "high power", as in how much can a t series handle....

also, what brakes, the axles? surely cant strip the teeth of the crown wheel and pinion..?

im running a 4agte and it blew the crown wheel and pinion(no teeth left on the pinion) but it lasted a fair while. there strong but not bullet proof.

[Craved]

Going by the list on page 1, an S315 diff as per my VIN plate would be a LSD?

[Patric]

A Majority of the diff info you want can be found here. http://web.archive.org/web/20090122152137/http://ourworld.compuserve.com/homepages/stepho/newcodes.htm Thanks wayback machine.

[-ollie-]

I have been looking all morning, but I cant find what ratio my ke70 is. Its an 1982 manual wagon, k-50 (5 speed). Some people say that its different to the ae71 borgie's, and it differs between 4 and 5 speed ke70 boxes.
Can anyone shed any light?

[Patric]

Have a look at the code on plate on your firewall. http://web.archive.org/web/20090130090221/http://ourworld.compuserve.com/homepages/stepho/diff.htm
Check cose at above link. It will tell you ratio.

[s14seriesII]

Code should be 282... For a 4.3, 2pinion open centre, small chance it could have a 4.1, but I doubt it

[odessy]

Would like to confirm that a t series from an ra60 is a straight bolt in swap? Think I have found one I can pull the diff out of, do I need the handbrake cable or anything else from it?

[johl]

yes i pulled one out at the wreckers and used it. there are rumours being spread that the trailing arms dont line up or some shit but that is entirely false as i have done it. as for handbrake cables i cant remember which ones i used but better grab them just incase

[Jacobxxx]

They line up but aren't ra60 a wider diff opposed to a t18 item?

[johl]

I'm not sure. I have used both and didn't notice a difference. So they must be either the same or pretty close for me not to notice

[odessy]

So an LSD for a t18 will fit in the ra60 rear end?

[Jacobxxx]

Ah okay, friend had an ra60 t series in his ke70 and couldn't even fit 13x7 +-0 on standard guards.

[s14seriesII]

yeh the ra40/60 diff is about 30mm in total wider.. so 15mm a side..

and the upper trailing arm bolt holes are not in the correct location.. it still bolts in fine but you will find that the pinion angle/flange is pointing up at a fair rate,
for lowered ae's ke's this means the tailshaft rear uni joint and flange will rub the floor far more often

[ke_70]

also i think the diff sits abit further towards the rear. i have many clearence issues with my ra60 diff. if you want big wheels just go for a normal corolla t series.

also the spring perches are different, trailing arm are drilled 14mm, and they're ugly ratios too. 3.9 man 4.1 auto

[s14seriesII]

lol yes all true..

and ugly ratios.. lol

ive got a 3.9 in my restored ae86 street car and a 3.7 to go into my daily :) but i do like fuel economy !

[odessy]

What about the USDM te72?

[ke_70]

what about them?

[odessy]

lol, they come with a t series aswell? Did any come with a factory LSD?

[odessy]

Anyone know what diff the USDM te72 came with?

Also what is the go with swaybar mounts when changing to a t series?

[shift_rook]

is the ra40 back part of the tailshaft the same as 86? cheers guys

[Jimmee1990]

I'm possibly buying a kouki sprinter on the weekend with a disc brake open centre t series, is there any difference in axle length or splines between open and lsd diffs? Or can I just buy an lsd centre and bolt it straight up?

[johl]

just make sure you buy a kouki lsd. i believe zenki is 24mm and kouki is 25mm axel diameter

[FAST EDDIE]

I fitted a st162 diff to my ke70todat bolted straight up spring bases were smaller and panhardctod was in a different posi and taulshaft needed a bit of modding to fit but all quite simple easy upgrade and cheap

[s14seriesII]

could this be the worlds first front wheel drive ke70 ?

[Golberg]

could this be the worlds first front wheel drive ke70 ?

Had a chuckle at that myself

http://www.roblincolne.com/pix/girlfriend.jpg

:yeah:

[Jimmee1990]

I've been told by a few people that to fit an lsd to my kouki t series, that i'll need to grind roughly 5mm off the end of the axles because open centre axels are longer than lsd axles. Anyone have any knowledge on this and can tell me 100% what's up?

[Golberg]

What kind of LSD?

[Hen may possibly be a nut]

Jimmeeeeee, I'm just repeating internet wisdom here, but I think axle length is only an issue for factory Toyota LSDs. All aftermarket LSD centres can cope with the standard (open centre) length axles.

However it is incredibly easy to check. If your axles bottom our before they should then you'll need to trim them. 10 minutes with an angle grinder and file and an axle is shortened.

[FAST EDDIE]

[anastasios]

hey guys, what is the rear sway bar diameter of ADM ae86?

[Ktas]

anyone have info about AE85 S-series?

[s14seriesII]

Ae85 S series in theory is exact same as our adm S series

[Ktas]

have heard rumours of them having the same size drums as t-series...either that, or do t-series drums bolt on to s-series?

[s14seriesII]

I'm pretty damn sure I've put t18 drums onto S series brakes.. So yes.. That was a round about way of asking it though ?

[Ktas]

little bit...im just pissed at myself for being lemon'd...wasnt even thinking when i got it

[Ktas]

so...ra40 t-series...just want to clarify...

it bolts in no worries, without pinion angle change?

spring seats are fine to use with ae86 springs?

does the panhard rod need to be a special length, or will a normal adjustable ae86 item do the job?

and obviously an ae86 lsd will fit into the ra40 center?

thanks for bearing the painful questions

[Still Steppin]

any answers for the above questions?

[Golberg]

I personally haven't tried it, but my understanding of the RA40 diff into an E7 or 86 is that the trailing arm mounts are a little different in their location, but they can be squeezed in. You'll just flog out trailing arm bushes quicker.

I think the spring perches may be smaller too.

They aren't a bolt in drive away afair. Nothing is, unless it came from an AE86 to begin with.

Even E7 diffs are different in their hand brake cables, so aren't a perfect fit.

A Zenki AE86 LSD will fit an RA40 centre.

[billett86]

anyone know of anywhere to get the anti vibration clips that come out of a jdm t series and that go between pad and caliper?

[Golberg]

Unfortunately most of them are discontinued, so generally speaking, second hand is the only way.

They aren't necessary per se, but they do help to make your brakes quieter.

[Still Steppin]

ok...did a bit more diggin and found the following...

************************************************** ************************************************** ************

I have compared a JDM AE86 Kouki housing to an RA40 one just yesterday. The results are as follows:

Upper trailing arm spacing Lower trailing arm spacing Spring hat spacing.
RA40 519mm 977mm 950mm
ae86 494mm 980mm 930mm

Note: the springs and upper trailing arms are not in ideal positions. Springs are quite elastic and should bridge and flex. The upper arms are very short and sit on a bit of a dodgy angle when flexed 13mm sideways. Id suggest an upper arm cut and weld mod to get it right.


As for the springs:

RA40 springs have a tight wound tapered end whereas ae86 ones have two fat ends. You will need RA40 springs for the diff end as that is the end where the spring tapers. Note coronas etc were very similar and springs will interchange.

As for the trailing arms:

The RA40 trailing arms are identical length units to AE86. Different bushes though. I have taken rough measurements and the cup diameter looks much the same.


As for the forwards or backwards offset of the mounts and how they compare to one another:

The RA has mounts 10mm further forward on the housing for all the suspension arms including the panhard rod. Their relative positions to each other are all much the same, but the RA diff will sit further back using the AE86 floorpan mounts and suspension arms.

As for the panhard rod issue:

Yes the ra40 panhard rod is a different length to an ae86. The pin to mount the rod is in a different position on the RA40 diff, making the rod about 50mm shorter than the AE86 one. Im not sure how the mount on the floorpan will compare from the RA to AE86. I have not checked. Use an adjustable rod.

As for the tailshaft:

Im not sure at this stage about whether you can use the RA40 rear section or not. I measured the length from face to face on the ra40 one, it is 760mm. In my opinion if it is about 10mm longer than a t18 rear section then the RA40 rear tailshaft section will be fine, and will effectively lengthen your wheelbase by 10mm, when used in an AE86. This could be why you have to force it together when using a t18 rear section, since the trailing arms are all the same length from RA40 to AE86, but the RA40 diff is sitting further back due to its mounts being further forwards on the housing.

SOMEONE WITH A T18/JDM TAILSHAFT SITTING AROUND PLEASE MEASURE THE REAR SECTION. My guess is 750mm.


As for the bushes:

The centre bolt is larger on the ra40 bushes/diff. The outer bush cup size is the same on both cars, according to my measurements. Note, I have not actually fitted it yet, but my assumption is I would use an RA40 bush one end, and aa AE86 one the other. Look to the info above for real practical advice.


As for the Swaybar:

The RA40 diff I looked at had no mounts on it. The JDM one does. You will need a welder.


As for the Brakes.

Most RA40 diffs have drums on them. Not sure of their size but I suspect they are slightly larger drums than AE86. Only RA40GTs came out with factory lsd and disc brakes. That diff pictured is very rare and expensive. Don't get your hopes up of finding better than a drum braked, open centre 4.1 ratio.

The width from one mounting face to another is 1410mm on the RA40 diff. Not sure if a JDM diff is the same as I was comparing a housing to a complete diff. Hope this settles a few bets.

[LittleRedSpirit]

You can jump onto us ebay and search for ae86 brake pad fitting kit and you should pull up the set of clips for the rear caliper.

[dogan]

I had a RA40 T series diff in my old AE86.

I used the standard ae86 trailing arms, the ra40 handbrake cables, t18 rear half of the tailshaft and a whiteline adjustable panhard rod.

The whole diff pretty much bolted right up, I didn't have much trouble with the arms being on any strong angles or anything. Although you could see how the trailing arm brackets on the diff are in slightly different locations than they are on a T18 T series. Thats also the reason why the pinion will be slightly pointing up compared to standard.

The spring seats are definitely smaller but it's not so small that your springs would fall through or anything. If you're worried about the chance of the springs falling through then forget the idea of putting a cheap RA40 T series diff into your car and fork out whatever you need to for a T18 T series or an AE86 item.
Oh and all T series centres are interchangeable between each other, it doesnt matter if one is out of an ra40 or a t18 or an ae86. I had a T18 centre with a TRD 2 way in my ra40 t-series.
FYI when putting a TRD 2 way lsd into a ra40 t series you need to shave roughly 5mm off the edge of the axle to get it all to fit.

Wrong.

The carrier and crown wheel & pinion are usually interchangeable, but there are 2 different diameter axles depending on the year of manufacture. Later AE86's had larger axles, October 1985 they switched to a larger size. All centres before that were interchangeable.

[anastasios]

will kouki JDM handbrake cables disc brake work with my AE71?

[Still Steppin]

with the use of spacers or a jdm ae86 front half cable you will be fine

[anastasios]

what do you mean front half? the bit which the separate cables hook into?

Sent from my GT-I9100T using Motorculture mobile app

[Golberg]

I ended up using the disc brake liners but replacing the inner wire. The cable clamps on the body are in different locations to an AE86, so when the cables are installed they're too short.

I don't know about the AE86 front cable section, but I its plausible.

[Still Steppin]

yes, the cable that attaches to the handbrake lever itself...it is shorter in the jdm 86, and t18...

[Golberg]

Its shorter?

That'll make the problem worse then.

The AE86 cables wont reach the E7 front section.

[Still Steppin]

really? odd

i know thats the case with t series into 86...have done it into 71 and it was the same deal

[greeneyes]

I fitted a Celica RA60 banjo in my KE70. All the differences are here-

http://www.rollaclub.com/board/topic/65709-how-to-fit-a-celica-diff-to-a-ke70/

[dove grey 64]

Will a front 4wd tarago cr+p fit a t18 diff? Its from a auto, any idea on ratio

[Jacobxxx]

Will fit if its T series
Think from memory 4:5?

[KurtHS]

The gear set from the lite ace (4.5) will fit any T series centre.

[Golberg]

I'll just add a note there, a liteace gear set will fit. But only from the front diff of a 4WD one.

I don't believe any tarago's had as small a diff in the rear as a t series.

[dove grey 64]

We should sticky seal part numbers like pinion and axle seals. I've been doing my balls on finding them. Bursons are hopeless and already got me the wrong parts.
Hopefully bearing wholesalers gets it right

[s13 james]

Had a search that gave no answer, i have a drum t series with a 2way in my 86, im unsure what the t series came from,problem is i want to order some new drums, shoes, do all t series have same brakes so i just ask for t18 gear or are the brakes same as a s series?

Depends what the width is, if its 1410mm wms to wms then its probably t18, if its 1380mm its ra23/28, or 1440mm then ra40, from memory the ae86 s series drums are different but still interchangeable I believe, the wheel cylinders are the same and I'm pretty sure the shoes are the same

[s13 james]

Thanks mark il give it a measure, is there anyone out there that can confirm ae86 s series shoes will fit and work in a t series? Thanks

Hey. Just to let you know, none of those links even work.

[timmynz83]

Having a look at genuine toyota part numbers and the aus spec t18/te72 and the aus spec ae86 rear shoe kit share the same part number so I guess they are the same.

Toyota part number

Yea works in ebay iPhone app. Just not in safari on iPhone.
Thanks.

[s13 james]

Ok so for people in the future you can order brake shoes for adm ae86 and they are identical to shoes in a t series as i bought and installed today,i have a part number for shoes and front pads ill post tomorrow ,shoes were in stock too but front pads are special order

[PRP120]

Just like to add in that don,t forget about RT104 corona for t series stuff. From 75 to 78 all run t series ( and later but do change amongst models and variations like wagon, luxury ,etc) with many different ratio,s( 3.9, 4.1, 4.4 are ones I have come across) zenki size axles with drum brake. For an easy disc upgrade ST141 girlock bolt straight on incl handbrake ( not t series) so hope this may help sourcing cheap parts. Pretty sure from memory 1410 mm but don,t quote me but can double check if anyone requires. Hope this helps someone out.

[dove grey 64]

Pretty sure from everything I have read online st141 rear disk assembly's require a spacer ring to fit the rear end.
4.4 ratio t series diff center sounds good. Will start looking for one of them.
Anyone know if the speedo calibration goea out when changing from 4.1 to 4.3 or 4.4?

[Still Steppin]

yes the speedo calibration will go out...much the same as going with different sized wheel tyre combos affect it

and yes, you do need to run a spacer inbetween the bearing retainer plate and bearing for the disc upgrade

[Jimmee1990]

Yeah speedo will be off. Golberg sells the different speedo gear combinations to fix it though.

[PRP120]

Yeah sorry. AE will require spacer ring, straight forward for me as same size through out coronas(60mm). My bad....was in corona mode. Yeah ratio does change speedo. I've swapped speedo drive pinions/gears each time to suit. Corona 4 speed n celica 5 speeds(steel case) are exactly same so all good. From memory the 4.4 was from a 76 RT 104 manual wagon CS. Pretty hard to find.... Most are 3.9 and who knows if they hadn't tinkered with before I got my paws onto it.

[Golberg]

4.4 seems an unlikely ratio, never heard of it before. You can definitely get 4.1 4.3 4.5 4.7 4.9 5.1 5.3.

Anything above 4.7 is not a Toyota OEM part, TRD ones exist as do other brands.

Speedo is definitely effected by a diff ratio change, I sell the parts to correct your speedo in the event of a diff or tyre change: http://www.ae86drivingclub.com.au/forums/showthread.php/78082-T50-amp-W5-Odometer-Gears-Correct-your-speedo!

EDIT: Didn't see all the replies already, thanks guys!

[anastasios]

Hey guys,

when installing axles do you grease/oil any of the bearings/seals?

[Golberg]

The bearings on the axles are usually sealed so you can't actually oil them.

I'd put a wipe of oil around the seals.

[anastasios]

Does anyone know the part number for AE86 sway bar bush 14mm bar, Ive got a pair of super pro bushes and pedders bushes and they both dont fit. They are too big for the u bracket

[Brooklandsbob]

This might help someone out - T series outer oils seals (axle end) are kelpro 97079, 52x65x9. I just bought a couple so I know they are right

[Golberg]

Just as an aside, I'd strongly recommend staying away from after market oil seals.

I've installed plenty and wont every do it again. They often weep (due to a lack of oil direction fins) and usually fail much quicker than genuine items.

[Brooklandsbob]

bugger, thats good to know - can you get a couple of genuine ones for me???

[Golberg]

I'll PM you Bob.

[phreak97]

Hi,
I've got a KM20 Liteace and I'm looking for another diff, will only an E series centre fit in? or is there another one with the same bolt spacing, axle splines and input shaft?

regards,
James

[af300e]

If you like, I have a 4.75 e series centre I'd sell for a reasonable figure.

In fact, I have the whole diff from an ms40 I'd anyone is interested.

[phreak97]

I've already gone from a ~5.2 down to a 4.3, I'm thinking I want to go even lower to get better freeway economy, thanks for the offer though.
Just trying to work out what vehicle I can get one from. what's the lowest E series diff which is commonly available?
also do any cars use E series? or just commercial vehicles?

OR, is there a 5 speed column shift gearbox which will go onto a 4k?

or anything else I haven't thought of?

so many questions!

cheers!

[markiitourerv]

Think you'd find that a MX32 E series would be a 3.9

[phreak97]

I'll look into that, cheers!

[Futo_gt86]

ohk xt131 it was a hatchback

OK, So I don't see it listed in first post, but is XT131 a T Series rear end?
And if so what type, is it Zenki or Kouki?
Are there cheap / easy disc conversion available?

Help me out with some info Plz.

[Golberg]

I cant confirm.. but the XT131's were Australian built which usually means it'll come with some garbage borg warner diff.

[Futo_gt86]

So no LSD or spool available?

[Golberg]

TBH, no idea.

I personally think you're wasting your time and money with anything that isn't a banjo type diff.

Its generally quite expensive to have somebody transfer the mounts diff to diff (Usually $500+ for anybody has the proper equipement to check the straightness of the diff after all the welding).

So if you want a disc brake diff as strong as a T-series you're better off buying a JDM AE86 diff. Which will set you back $1000-1500 usually. Its only economically viable to do something else if you need a stronger diff.

[Hen may possibly be a nut]

So if you want a disc brake diff as strong as a T-series...
In this situation I'd recommend a T18 diff housing (or another T series that can be made to fit, RA40??) and Corona discs. Cheaper, more available, better handbrake, maybe even slightly larger discs (can't remember off the top of my head).

[Futo_gt86]

I ended up buying a drum brake series 1 T18 T series that came with the shaft and hand brake cables.
Is there a thread on the Corona Disc conversion?
Like what model Corona, how to step by step.

[Hen may possibly be a nut]

Have a look at - http://www.toymods.org.au/forums/engine-driveline-conversions/32132-%5Bguide%5D-how-fit-rt142-rear-discs-most-4-studs.html

The guy who starts the thread is a bit hardline about what you must do. But there are several options for a lot of things. Basically it's close to bolt up. You need to move your lower shock mount, have some form of bearing spacer ring and shorten the handbrake cables and there are multiple ways to do each. I think I even used the stock bolts to hold the backing plate on.

With the stuff in front of you it'll be easy to work out what's best for you.

I m trying to work out which liteace had t series diff ?

From what i read its the front diff of 4wd liteace,which would be a 4.77 ratio?

Never seen or heard of one,could any one confirm .Year and model would be great.

Rob

[Golberg]

Any 4wd liteace will have a T-series front diff. I've pulled out 2 of them. One was out of an 89 model, the other a 93. Both diesel 4.55 out of one 4.77 out of the other.

These vans are very rare in Australia as they are grey imports.

I don't rate your chances in finding one though. Mind you I did find 2 over the past 5 years.

Oh, and they are an absolute menace to get out.

[Futo_gt86]

Sedan sorted, thinking about the Van now.
Quick question,
Is there a leaf spring version of T series?

[corollaart]

Thanks Goldberg I went to my local toyta dealer looking for a 4.77 c&p which are still listed but retail over 1000 ,and trade 800 sum thing.

F##k that !!

I emailed wier but as normal no reply.

Looks like im heading for G series,not going to pay bs prices like that.

Thanks for info Rob

[dogan]

What tail shaft would I use for a S series diff in a Ke70 with a K50 gearbox??

[ae86 drifter]

ok so I've read some of the pages but just wondering if the t series disc 86 diff is offset to one side of both axles the same length?
Cheers

[Slimer86]

Axles same length I am led to believe. No identification on the individual axles to be be left or right side.
