Most of what you have said is correct. I only changed the bearings in there as I changed over to the RAM swing-arm and the magnesium eccentric.
The factory seem reluctant to allow us to go in there for some reason, but if you have done this type of work, and have access to a press, it is quite straightforward. Just make sure the eccentric housing is warm before you start, and it all goes easily.
There is a roller bearing on the LHS, which could use a lube after - say - 30,000 miles. This bearing is readily available for not too much; its SKF number is RNA 4910.2RS.
The other is a bit harder.. It is a double-row bearing, with one outer case and two inners. It appears to be a 'special', made to spec for Ducati. It cost me a lot - I forget exactly, but I seem to remember over $150.
The tough part is that SKF will only supply them in batches of 25.. Its SKF part number is BAH-0175.
Fortunately my bearing supplier was able to source me one through someone in the UK (who had obviously bought the 25) and could supply me one.
Unfortunately I don't have a name for this character, but I can give you the name of the (Australian) business who sourced mine if you want. Shoot me a PM if you want to pursue this.
