duncmc Posted March 5, 2011 Share Posted March 5, 2011 I have discovered that the LT230 transfer box on my 90 has been replaced with a genuine service exchange unit at some point in its past. Is there any way from the model no ST08692E and serial no TB00677 to find out when it was reconditioned or its ratios? Thanks Quote Link to comment Share on other sites More sharing options...
western Posted March 5, 2011 Share Posted March 5, 2011 As it's a genuine LR exchange, most likely a 1.410:1 correct for a Defender. the serial number is a 7 not T at the front, so it should read as 7B00677 Not TB00677 Quote Link to comment Share on other sites More sharing options...
duncmc Posted March 5, 2011 Author Share Posted March 5, 2011 Thanks Western, its definately a "T", I have the full res version and there is an obvious difference between the "T" and the "7". Thanks. Quote Link to comment Share on other sites More sharing options...
western Posted March 5, 2011 Share Posted March 5, 2011 bit clearer now, defo a T so it'll mean TB = Transfer Box 00677 part number looks like STC8682 found this one Britcar website http://www.brit-car.co.uk/product.php?xProd=94016 comes out as STC8682E found STC8682E in my microcat parts info, it states transfer box prefix 22D for 4 cylinder TD/5speed manual or prefix 25D for V8/5 speed manual both for 110 vehicles. 1.410:1 ratio hth Quote Link to comment Share on other sites More sharing options...
duncmc Posted March 6, 2011 Author Share Posted March 6, 2011 Thanks Western. That makes sense now. STC of course being a part number, I can see it now. E for exchange. Cheers. Quote Link to comment Share on other sites More sharing options...
