Gremlin Posted October 27, 2020 Share Posted October 27, 2020 Hi All Time for me to ask the collective wisdom of this group. Going to install a 4 pin 24 spline center. Now am i right in assuming that if i do not disturb the pinion, all i need to do is re-adjust the backlash? Let me know if i am wrong..........

Snagger Posted October 27, 2020 Share Posted October 27, 2020 Correct to my understanding. I suspect that you could also renew the pinion bearings with the same spec and it’d be within tolerances, but you’d need to check the depth afterward just in case.

Vogler Posted October 27, 2020 Share Posted October 27, 2020 I wouldn't be too sure about that. I recently have rebuilt the front diff and LT230, and have noticed several times that new bearings result in differences. I had to replace the pinion so I couldn't compare the effect of new bearings. However, measurements changed in the LT230 which is quite a comparable situation given the fact it also has tapered bearings. Make sure to properly loctite the crown wheel bolts with loctite 270. I also used allen bolts with Nordlock rings. The Land Rover bolts (FTC5150) tend to 'eat' their way into the steel, resulting in play and eventually breakage. This was the reason for abovementioned rebuild (Td5 100k miles, after a holiday with lots of corrugations). Greetings, Joris Quote Link to comment Share on other sites More sharing options...
Snagger Posted October 28, 2020 Share Posted October 28, 2020 A replacement set of bearings with the same numbers from the same manufacturer should work, but there are different spec bearings that fit the same internal and external diameters which may have different depths, and I wouldn’t be sure that the same bearing numbers from different manufacturers are identical. But as I said, you’d need to check the pinion depth on completion to be sure. Quote Link to comment Share on other sites More sharing options...
Gremlin Posted December 5, 2020 Author Share Posted December 5, 2020 Diff assembled, any opinions on the pattern? Grem Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 5, 2020 Share Posted December 5, 2020 Pinion too far in, but then I am guessing you haven't changed the the pinion set up if you are just changing the centre? Or are you changing the ring gear as well? Quote Link to comment Share on other sites More sharing options...
Gremlin Posted December 5, 2020 Author Share Posted December 5, 2020 No just changed the center. To me it looked ok on one side and so so on the other. Grem Quote Link to comment Share on other sites More sharing options...

Ex Member Posted December 8, 2020 Share Posted December 8, 2020 Never change the pinion height on a used ring and pinion. A used gear set wears into a pattern. If you change the pinon height, it will run in a different spot and not work well. 1 Quote Link to comment Share on other sites More sharing options...
