driesdej Posted May 19, 2017 Share Posted May 19, 2017 (edited) HELP pleeeeese !!! I have a 1991 200Tdi 110 Defender, and while on visit during April I bought a new centre portion for my front diff in South Africa. I live in Madagascar. I sailed back and started the dismantling of the old and to my horror found out that I have the 10 spline side shaft diff and the new one is 24 spline. No way I can hop back quickly and replace . . . so what do I do now? Can I use the 2 old side shaft gears in the new one (there are 2 spider gears and the 2 gears on the side shafts – page 410 No 2 in parts catalogue) OR can I buy 2 new 24 spline side shafts and replace my old 10 spline side shafts with them? OR am I stuck???? Any help will be well appreciated. My nearest LR dealer is 1000km’s away.

miketomcat Posted May 19, 2017 Share Posted May 19, 2017 I've fitted 24 spline internals in a 10 spline rear axle. I'm pretty sure you can do the same at the front but you may need to change the cvs as well. Assuming it's a metric axle. Mike Quote Link to comment Share on other sites More sharing options...
landroversforever Posted May 19, 2017 Share Posted May 19, 2017 Nigel will know if the gears are interchangable. How many splines are there in the inner part of your CVs? If they're 23 splines then you could just get a set of after market shafts from Ashcrofts which will be 23/24 spline. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted May 19, 2017 Share Posted May 19, 2017 I would expect that replacing the driveshafts & flanges would sort it, although which combination I'm not sure. Needs Nige to wade in really. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted May 19, 2017 Share Posted May 19, 2017 AH If only life was that easy ! On centres there are different gear types forged and cut, and also differing center casings and even differing pin sizes all on the standard 2 pins. To be honest messing about with a 2 pin will prob give you grey hairs and may work 1st time or not. Mixing gears is also a bad idea from mixing wear patterns, the 2 pin centre is already weak enough ! If you now have a 24 spline centre best route would be to upgarde to 24 shafts which even standard are stronger, here is a video, although its on front shafts the 10 / 24 argument is 100% valid ! Hope this helps, ask if you want any more info : Nige Quote Link to comment Share on other sites More sharing options...
driesdej Posted May 21, 2017 Author Share Posted May 21, 2017 Thanks Nige Wow, this was most helpful. Now i need to contact dealers in the capitol to hear if they have 23/24 front side-shafts Regards Dries Quote Link to comment Share on other sites More sharing options...
driesdej Posted May 30, 2017 Author Share Posted May 30, 2017 Hi Nigel, Need yourr help again. Before ordering new 24 spline side shafts i had a look at the old and the new centre portions. The old: Crown wheel - 46 teeth, Pinion - 13 teeth, Side shaft gears - 16 teeth and Spider gears - 9 teeth = it has 10 spline side shafts New: Crown wheel - 46 teeth, Pinion - 13 teeth, Shide shaft gears - 14 teeth Spider gears - 9 teeth = it needs 24 spline side shafts Question - it is only the Crown wheel and pinion that realy matters to give you the same ratio OR will i have to hunt for a complete identical centre portion to my old one ???? Help much appreciated Dries - Madagascar Quote Link to comment Share on other sites More sharing options...
landroversforever Posted May 30, 2017 Share Posted May 30, 2017 The crownwheel and pinion ratio is the only one which matters as far as I know. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 30, 2017 Share Posted May 30, 2017 Yup, ignore the internal gears, they only allow the slip between wheels, and do no determine final drive ratio. Quote Link to comment Share on other sites More sharing options...

Hybrid_From_Hell Posted June 1, 2017 Share Posted June 1, 2017 The CWP teeth gives ratios, So 46 on CW and 13 on pinion = 3.538 (3.54) same on Ashcroft HD 28 / 8 = 3.5 these have to be the same each end (ok to use ashcroft 3.5 and std 3.54, I mean you cant have 4.1 one end and 3.54 on the other - and yes I have known itr The gears in the centre - sun or pkanet are a SET, differing SETS have differing numbers (and styles) of gears, but the SETS allows the differewntial movement nothing more, so any centre is fine providing the SET is all matched Hope this helps and makes sense ?
