to remove the basket takes a 'special' tool, and a LOT of impact torque.
the tool holds the basket by 3 (or more) of the clutch bolt pillars. I forget the actual value of the tightening torque on the nut, but I believe its way over 100 ft/lbs. then they stake the nut to the shaft. to remove the nut will require enough removal torque to get past the staking of the nut, as well as the removal torque (which will be considerably less than what it takes to get past the staking, but still over 100 ft/lbs.)
as far as dry frictions, while mine where not bone dry, they where not dripping with oil either. I think its normal.
while every time I removed the clutch disks and plates and reassembled, coffee grinder was gone, it did return. HOWEVER I was NOT replacing my disks or plates. I did run the steel plates over a nice flat surface with some 800 wet/dry paper and some oil on it to break any glazing that was on them
