T18 diff. Which axles?

[maxhag]

fellas,

I have recently pulled out a R31 modified diff (KAAZ 2 -way) in my track 86, as I was having problems with it.

Anyway, I had a T18 (drum) diff, with TRD 2 way (havent checked, but what I was told) sitting around that I bought off a good mate last year. I have just almost finished putting the diff in the car.
The car is a drift car, and a very experienced AE86 drifter friend has told me that I will snap axles. I have never had a T series before, and I dont know the fine details about them. I went straight from S series to R31 in the past...
I want to get some spare axles as I have entered a comp, 10 hrs drive away. Do comp, and drive home again :P I dont want to get stuck..... Gonna even do some fishing on the way :P

So my real question is: What axles can I use for that setup? T18, Can I use other model axles? Do I have to modify anything?

I have read some things about cutting them down or something, but conflicting with other stuff. I figure this is the best place to get a straight answer.

Sorry if this is a repeat question, but I couldn't find a definate answer in a search.

Thanks guys,

JoJo

There is a whole kit you can buy from MCN sport I think with full spool and stronger axles to handle around 300hp, pretty pricey though.

[Delazy]

Yeh pricey and only fits a jdm housing...looking into purchasing direct from weir spence in the US atm...

Hey Jojo. Only the t18 axles fit in the t18 diff, even though it shares the same centre as the ae86 early/zenki disc brake diff.

The difference between them is that the t18 axles use a single row bearing, where as ALL ae86 t-series disc brake diffs use double row bearings.

[jakel]

^ Pretty sure that's the larger axle diffs?

[shortround]

Nah zenki and kouki use the double row bearing. I've got one of each spare in my shed.

[jakel]

Ah, any chance of fitting the other bearings to those axles?

[Jimmee1990]

As far as I know all drum brake t series used the same bearings, and only disc brake diffs have the double row bearings?

[maxhag]

hmmm, once again, conflicting opinions/info.....

Do we have a clear answer?

T18 - yes
Drum 86 - ? Zenki or Kouki?
Disc 86 - ? Zenki or Kouki?

I believe Jimmiee1990 is correct that the AE86 t-series drum brake diff also use the single row bearings, but these are quite rare.

So axles that will fit in a t18 diff:
* T18 axles
* AE86 zenki/early drum brake axles

No kouki/late ae86 axle will fit in a t18 diff! disk or drum.

I read that it might be possible to just mount a single row bearing on a AE86 t-series zenki/early disk brake axle??? but I'd guess it would be cheaper to buy t-18 axles than AE86 ones??

Thought about billet axles if you start breaking them Jojo? My mate got some made in Canberra for about $400 each.

cheers, thanks mate

[jakel]

I thought so!

Sorry to be a pain, but can I use AE86 Zenki Disc axles? Or AE86 zenki drum axles only?

[Jimmee1990]

Only zenki drum axles, the disc axles are completely different and use a double row bearing.
