kwalker705 Posted March 12, 2014 Share Posted March 12, 2014 Did a little diff swap over with another forum member Need this one Identified to ensure I get the correct seals/LSD for it from Mr Whiffin. Ideally an A--- code would be great. So any help identifying it would be splendid guys.

David P Posted March 12, 2014 Share Posted March 12, 2014 (edited) It's a small casing Torsen, (A0?B code) but can't tell the ratio, what was it off? Edited March 12, 2014 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted March 12, 2014 Share Posted March 12, 2014 I'd guess an AO2B small case auto diff. Quote Link to comment Share on other sites More sharing options...

kwalker705 Posted March 12, 2014 Author Share Posted March 12, 2014 I'll grab some more pic later of the teeth and the pinion wheel teeth aswell if that will help. Plus I have another diff to open and if its different I'll need that identified too Quote Link to comment Share on other sites More sharing options...
David P Posted March 12, 2014 Share Posted March 12, 2014 VIN plate or engine/trans info would be simpler. Quote Link to comment Share on other sites More sharing options...
kwalker705 Posted March 12, 2014 Author Share Posted March 12, 2014 Don't have that luxury im afraid. Really wish I had access to the vin plate for the car it was removed from now. Quote Link to comment Share on other sites More sharing options...
David P Posted March 12, 2014 Share Posted March 12, 2014 What engine/trans combo was it? Quote Link to comment Share on other sites More sharing options...
mellonman Posted March 12, 2014 Share Posted March 12, 2014 To be fair dave these cars have had so many changes,a vin plate may not hold the truth,N/A -TT and the like Quote Link to comment Share on other sites More sharing options...
David P Posted March 12, 2014 Share Posted March 12, 2014 Simpler than opening it, you can count how many turns of the prop flange for 1 turn of the drive-shaft flange. 4 = N/A, 3 3/4 = T.T. auto, etc. Quote Link to comment Share on other sites More sharing options...
kwalker705 Posted March 13, 2014 Author Share Posted March 13, 2014 I might be a spaz here... but if I count the amount of teeth on the crown wheel, and divide it by the amount of teeth on the pinion will this give the ratio ?????????? are certain ratio's specific to certain diff codes ??? I initially purchased this for my 6 speed aristo as with the auto aristo diff at 80mph the car was at about 3000+ RPM so was hoping to get a manual diff to match the box. The one I have is supposed to be a manual one. Casings are the same as the one pictured, but I've not opened it yet. Quote Link to comment Share on other sites More sharing options...
