Hi feelyx,
I may one day see a IMS shaft and fully understand the detail of the bearing mounting but from what I have seen from photos etc makes me wonder.
a) placing 2 x 6204 bearings side by side is a no no. The deflection due to loads will cause the shaft to bend place a moment on the inner and outer bearing which they were never designed for. The only way to overcome is to use a self aligning bearing, maybe a sinle row spherical roller but then you have problems with sealing.One would have thougth if P engineers asked for a special arrangement it would have been signed off by the bearing supplier? This a very interesting topic, but my peace of mind... unscrew your oil filter evey 3000 klm or less and look at the filter, ALL OIL that goes through the engine must PASS through the filter first. How cheap is that?
