Dikiy Posted February 26, 2008 Share Posted February 26, 2008 Anybody knows, is it possible to attach 4pin diff from P38A to the Discovery R&P and use with Disco axels? Quote Link to comment Share on other sites More sharing options...
vinny Posted February 26, 2008 Share Posted February 26, 2008 AFAIK The entire diff is not a direct swap the nose on the p38 diff is shorter. I remember reading in the comics that the p38 diff can be machined to fit the disco diff housing and use the disco crown and pinion Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 26, 2008 Share Posted February 26, 2008 Why not just use a 4 pin centre in a standard Discovery diff? Ashcrofts do them. Quote Link to comment Share on other sites More sharing options...
Dikiy Posted February 27, 2008 Author Share Posted February 27, 2008 vinny Comics? What do You mean? Why not just use a 4 pin centre in a standard Discovery diff? Ashcrofts do them. Yes I know about Ashcroft. Also I know about 4 pin diff from D90 rear axel and ARB, KAM, Truetrack and its... I'll go with ARB in front in future, but now I have already ARB in rear and 2 rear assembled diffs from P38A and I want temporary install 4pin diff (must be stronger than stock 2 pin) to the front axel. Still waiting for answer Yes or No otherwise will try to swap in nearest weekends Quote Link to comment Share on other sites More sharing options...

Dikiy Posted March 3, 2008 Author Share Posted March 3, 2008 Here is the results: REM-1&REM-2: More space will need for P38A diff casing. Diff casing will be machined to the same diameters as 2pin diff. REM-3: Difference 3mm between "upper" bearings position REM-4: Difference 6mm between crown wheels position The major problem is to compensate 6mm difference by moving diff assembly to matching crown wheel position will cause changing of bearing positions. The "upper" will move approx 3mm inside bearing case (no problem with thread) and "lower" will move approx 6mm outside of case- this is the problem, because not enough thread for diff lock ring. This problem can't be a solved by simple machining but I hope to find solution how to move bearing closer to diff casing. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 3, 2008 Share Posted March 3, 2008 Dikiy, I take it it works then It looks like a lot of work to do though ! Mo Quote Link to comment Share on other sites More sharing options...
BogMonster Posted March 3, 2008 Share Posted March 3, 2008 Dikiy,I take it it works then It looks like a lot of work to do though ! Mo Exactly - and the P38 diff isn't exactly reknowned for long life either. Before anybody says "it must be squaddie proof because the Wolfs use it" - check how many they break Nice bit of work though Quote Link to comment Share on other sites More sharing options...
