thanks for the info...the bearing holder looks like it is 2 piece? do i rotate like a ratchet (like with a little force)..or simply rotate it and reinstall the bulk head? I took it apart yesterday and it just seems like it wants to lift out of the bearing holder and only fits in there one oblong way...lol sorry i told you i was a newb..
