ejparrott Posted November 27, 2015 Share Posted November 27, 2015 Not guaranteed though, I've got a 28D but it has a 1.192 label which appears to be correct Quote Link to comment Share on other sites More sharing options...

western Posted November 27, 2015 Share Posted November 27, 2015 Not guaranteed though, I've got a 28D but it has a 1.192 label which appears to be correct IIRC that's a Range rover transfer box. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted November 29, 2015 Share Posted November 29, 2015 I believe so, but it's not supposed to be stamped 28D according to Ashcrofts! Quote Link to comment Share on other sites More sharing options...
western Posted November 29, 2015 Share Posted November 29, 2015 I believe so, but it's not supposed to be stamped 28D according to Ashcrofts! 29D is a 1.192 as well according to the list above, maybe a missread 29. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted November 29, 2015 Share Posted November 29, 2015 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 Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted November 29, 2015 Share Posted November 29, 2015 The only real way to get the ratio for certain is to count the teeth..... The difference between a 1.192 and a 1.211 isn't much per rotation. .... Quote Link to comment Share on other sites More sharing options...
ashtrans Posted November 30, 2015 Share Posted November 30, 2015 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, Dave Dave Quote Link to comment Share on other sites More sharing options...

Rasmus Posted May 10, 2021 Share Posted May 10, 2021 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 Quote Link to comment Share on other sites More sharing options...
