First an exploded view (from J. Platt's catalogue, with apologies to all concerned)
Photo of front end parts - n.b. I'm missing the flange nut at present.
So it goes nut - lock washer - flange - key - bearing retainer - bearing (R&M LJ7/8)
Photo of rear end parts
Nut - lock washer - A/C bearing pair (R&M LJT1, thrust faces together) - bearing retainer - distance piece - bearing (R&M MJ1)
n.b. if you're super observant you'll notice my bearing nut has a RH thread, apparently not many do.
My distance piece is rather worn and I think not original; but consensus is it should be 0.625" long.
Here's a close up of the bearing retainer
The retainer is 0.585" deep, 2.485" OD, 1.935" ID, 0.15" flange thickness, 4 equispaced slots on flange OD each 0.25" wide and approx. 0.05" deep, it has a RH thread about 2.305" OD 2.235" root dia & 16 TPI, with 0.075" undercut up to the flange (all measured quickly with vernier calipers).
Finally a shot of the set-up I will use to measure run-out of the crown wheel / diff cage, not quite there yet as it needs to be bolted up, CW in place etc. I only add this snap because when Jack French - for whom I had the greatest respect - said 'spin it on a half shaft' I think it was an off-hand remark and you need something a bit more robust if you are going to measure 0.004" precisely.
Hope this answers your question Damian and do let me know if you need anything more, I can just as easily add the banjo end parts if you need them.
Thanks Chris - that is absolutely excellent - much appreciated. It would be good if we could switch all these images to the main thread so they don't end up buried in the 'wants' section.. BW Damian.
