    Default Difference between the 10s & the standard 10 differential

    Hi guys,

    I am looking for information that would explain the difference between the 10s Differential and standard 10 Diff.

    Can the standard 10 diff assy be put in to the 10 s box.

    As far as I know there isn't a difference in the diff itself and can be interchanged. I'm not sure of the very old R8 diffs in the earlier '60s but when the 10s came out all that was the same. On the R8 Gordini is a difference in that it has 4 spider gears instead of the 2 in the standard R8/R10 boxes.

    If you are going to change that you'll have to make sure that you study the manual in detail to get the pre-load correct on the carrier bearings.

    I'd have to check my parts books, but I thought there were stronger sun and planet gears in the 10S or even later R10 transaxles. CW&P and ratios were unchanged and bearings etc the same AFAIK.

    When I got my 10S box, it was recommended (mid-1980s) as the best of the R8/R10 boxes, and I thought it was those diff internals but I could be quite wrong.

    John from memory of the ones I have taken apart the earlier ones had larger 10mm detent balls in the shift rods and heavier splined planetary gears !

    Thanks Manic.... I didn't know about the detent ball size! But I though there was something in the planetary gear system.

    They are all Type 330 units, and I think mine is a Version 33 or some high number. It was given new energizer springs in the synchro units and a minor reshimming of the crownwheel carrier bearings back in 1985 or thereabouts. Maybe it was 1977. I can't remember but it is still perfect.

    Oops, didn't think the 10S was that special. However it will fit.

    Pretty much identical externally. For Oz, the 10S was a production run of probably 1200 (that's how many sets of Australian-made VDO gauges they bought). I've no idea whether they deliberately used a slightly upgraded gearbox - I suspect not and that the later R10s just had that gearbox as it was the then-current version that came from France. Whether anyone actually knows nearly 40 years later...…..

    Thanks for the Info everyone. The 10s box I have is in a Motorkana special and the splines coming out of the diff, which the uni's slide onto, are moving up and down and side to side, so when it is altogether the wheels wobble. The scrutineers don't like it.

    I have a standard 10 box and was considering just putting the diff assy in as a quick fix. I only use 1st and reverse, 2nd has been blocked some how.

    I would just fit the complete 10 box that you have as I expect your 10S box to be very tired from all the fiddle brake use. You really shouldn’t just put only the main hemisphere from the 10 into your 10S box as the pinion is not matched to it. The 10S was the latest version that we saw of the 330 type box, but I too didn’t think it was that special.
