Guys I made it!!
Yes, but the other way around. First I removed small bearing
housing from above (position 64), then small bearing (position 72, bearing is 6306), then
lock nut KM7 (position 61) by using
socket wrench and then whole blade carrier and
shaft can be pulled from down under. After that, i removed 6 bolts (position 55) and whole lower bearing housing came down too (position 52. Then i pushed lower bearing (position 45, bearing is 6308) out from its housing and sealing ring too (position 49). It took me 30 minutes and almost no effort for one unit (there are 12 units, i dissasembled 2 today) . All parts are cleaned now, i will buy all lower bearings and sealing rings (12 pieces each) becouse they are in bad condition at Friday and continue to replace them all. Upper bearings (6306) are in good shape so I will not replace them now.
I will make some pictures tomorow, i totaly forgot to do it today becouse i was simply to excited
