Excuse me,
I think you mean the pilot bearing or bushing.
Throwout bearings don't even touch the input shaft at all (ever)
They ride on a sleeve surrounding the input shaft and press against the clutch release fingers/spring levers whatever.
Only a dragging clutch disc or pilot bearing can cause drag on the input shaft.
It would still have to come out though, for either one if it's not the adjustment on the clutch lever.
BTW new clutches need adjusting really soon after a new one is put in, then they last awhile before needing another adjustment.
