ta22 gearbox/diff problem

[kolby]

as its a customised tail shaft it wont bolt straight up.
but o man you have hit it on the head!

I dont now why i hadn't thought of it as thats what i actually did to the other every day driver celica (one with buggered gearbox) a few years back.

Thankyou! Needed someone to be thinking in a way i wasn't at the moment!

2. T50 doesn't have a removable bell housing. So no you can't put the t bell on the w. .

T50 have removable bellhousings (Ks dont) but matingsurface and boltpattern is different to the
W-series gearboxes.


Since were on the topic : Do D and T diffs share axel splines so if you want a LSD
in a D series you can get away with just changing diff head to a T-series?

when i was fiddling with my diff problem we chucked a couple of later 74,75 celica diff axles in it and they were fine.

would they be t series?

if so the it must be possible

There are 2 different rear wheel bearings - a smaller and larger. Not sure when the changeover was, I think it was late in the TA22 series after the conversion to T series. I have heard that the axles from D series will fit a T centre, but cannot confirm. You would be best to just chuck in a whole T diff, as they are cheap enough. Possibly an RA23/28 diff?? I don't think there are any mounting differences between them and the TA22 units.

Thanks, reason I asked is narrow celica diffs are becoming rare up here but a carina ta60 head is easy enough to find ..

You can bolt any t series series centre in the t series housing but no a t series centre won't fit in the d housing as the d is smaller.

And the t50 sitting in my scrap pile says a t50 from a ta22 doesn't have a removable bellhousing or should I say swappable with anything else as it is the front seal for the gearbox

[kolby]

that is interesting.. So what where the t series diff's found in? Where they in the later celica's?

When i put the centre out of the 76 ta23 into the d19 d series diff it went in ok but the flange bolt patter was different...

Off the top of my head ta22 ta23 ra23 ra28 ra40 ra60

Yer a d series diff is a smaller size so they are not interchangeable

[o_man_ra23]

The T series centre *may* fit. The D series may have had a larger housing for mass production purposes. If you can fit the T in and the axles fit, then I can't see why you wouldn't be able to use it (remembering you need the tailshaft flange changed out on the back uni). Something which you would need to experiment with, as I have never done it.

Also with a T series diff were the T18 and AE86 from the Corolla fraternity.

We once tried to put a t292 in a d housing in a flatlight 72 model and it didnt work. Not sure of why as it was a long time ago but it may have been the bolting pattern or it just didn't fit through the hole.

[o_man_ra23]

Righto... well then if the T292 centre fits in the housing, one might be able to infer that the housing is a T unit...

[lilcrash]

d series is 6.25 inch and a t series is 6.7 inch. So yer centers are definately not swappable

[o_man_ra23]

Been doing a bit of a look around, looks like the D series only uses 8 bolts to hold the centre into the housing, rather than the 10 bolts that the T series uses. So if you can slot the centre in from an RA23, its definitely a T series...

Belive 6.25 " is a S-series with 8bolt flange and D-series to be 6.62" 10 bolt flange .
