It's till possible. I've looked and looked and looked at it and I'm sure it's 28, the label appears correct on it though, 1.192

Hi,

the web list is a simplified version :

28D, sx B = 1.192

28D sx C to 308626E = 1.222

28D309143E to 551442F = 1.208

the above was then superceeded by the 36D in the disco 1's which were 1.211 (Q gears)

differences were tooth pressure angles and tooth count and tooth width, all changes were to reduce noise, the 1.211 (also used in the D2's and TDCi defenders) are the quietest but also have the weakest teeth as the teeth are smaller as there are so many more of them than the earlier ratios,

Hi,

I just got my hands on a LT230. It has the following serial number: 36D667628G.

 I suspect is a 1.211 ratio and it is a Q box (T design with more silent gears).

 

Can any help on when it was produced?

What vehicle it was fitted to?

Any things to be aware of on this transfer case?

Any other relevant info.?

 

Thanks Rasmus
