Series 2a/3 Rear Diff Centers

[keeffe88]

Gday All,

Picked up a rear Diff (Thanks Wazza) a few weeks ago, only got round to pulling them out and swapping them over today. I was in need of replacing Diff centers as bits of metal fell out if the old one when i drained it.

A few quick questions however:
1. In the acquired 2/2a diff there is a bar in the very center of the diff. This at the moment appears to be missing two pins on either side that stop it from sliding from side to side. What sort of pins are these? Are they necessary? The ratio is the same as the one that came out, slight differences in set up though. The 2/2a seems to have a recessed groove for the pins, whilst the series 3 one had clips on either end. Any help/suggestions appreciated on this...

And the plot also thickened a little.... When i pulled the diff off the car, there seemed to be no gears that were missing teeth??? Perhaps it was a remnant from an earlier broken diff? Im thinking i will still use the 2/2a diff center as it is in better condition than the series 3 one. series 3 one had a lot of surface rust in the diff center.

Cheers,
Josh

Series 3 diffs use circlips to retain the cross shaft/pin, Series I/II/IIA use split pins instead.

The split pin method is better! Series 3 and coiller diffs have failed because the cross shaft can rotate, wearing away the circlip, and once it falls off, BANG!.

Thanks Guys,

Ill be putting in the series 2A diff center with the split pins, this diff center is in better condition then the series 3 one that came out.

Cheers, Josh
