Chicken Drumstick Posted December 7, 2012 Share Posted December 7, 2012 We've just changed the transfer box in a 90. Foolishly we didn't check the ratio first as we were told with certainty that it was a 1.6 from a 2.5 mil spec 110. Once fitted the grearing seems really tall. So we checked the serial number and found a list on Ashcrofts website. It's a 14D which means its a 1.003 according this list: http://www.ashcroft-transmissions.co.uk/index.php?act=viewProd&productId=45 Anyone know what a 1.003 was used in stock? Also Ashcroft seems to list a lot of ratios above and beyond the regular 1.2 and 1.4. Out of curiosity what vehicles used all those other ratios? Thanks.

CwazyWabbit Posted December 7, 2012 Share Posted December 7, 2012 Have a look about 3/4 of the way down this page http://www.expeditionlandrover.info/gear_ratio.htm Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 7, 2012 Share Posted December 7, 2012 Early 3-speed auto RRCs used the 1.003 IIRC. Quote Link to comment Share on other sites More sharing options...

JimAttrill Posted December 7, 2012 Share Posted December 7, 2012 Interesting site. I have a cast extension to the Xfer box, quite a rarity as our local foundry put up their prices long ago which killed the demand. I sent one to Silvio in Italy for his TD5 and there were rumours they were going to make them there. An addition well worth having especially in a hot climate. Just a point of interest - the high-revving BMW 2.8 that was made here had the 1.67:1 box. This was long after they had stopped making them. I think it was last used in the 2.5 n/a diesel.

FridgeFreezer Posted December 7, 2012 Share Posted December 7, 2012 Could be interested in the 1.003 box if you're getting rid... Quote Link to comment Share on other sites More sharing options...

rick Posted December 11, 2012 Share Posted December 11, 2012 I think the Isuzu 4BD1 engined 110's made here used that high range too when behind the LT85, or at least it's the high range everyone wants, particularly when turboed. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted December 16, 2012 Share Posted December 16, 2012 Owners of modded motors might want to check their clearance first, I nearly bought one but a quick check revealed it'd be a bit too cosy with my exhaust. Quote Link to comment Share on other sites More sharing options...
