I bought a used MP10 a couple of months ago that ended up needing new bearings. Did some investigating and found this link:
I bought two 6x15x5mm bearings (P/N SMR696C-YZZ #5 NB2 from Boca Bearings) and set to work. The link above is pretty self explanatory but the guy used a bearing press to get the bearings off since the bearings on these are press fit on the rotor assembly so getting them off is not easy.
In talking to a friend in bearing manufacturing, he said to put the rotor assembly in the freezer for a few hours and the bearings should come of much easier since the tolerance should be only about 0.001 on such a small part. That did the trick! So now my MP10 is much much quieter than when I got it and cost me about $25, which is better than having to buy a new dry side from Ecotech.
Hope this helps someone needing to do the same thing.
PS: the bearings I listed above are hybrids (with ceramic balls) and are doing very well.
