    Anybody know how to get the shaft out of the adapter? I've removed the snap rings on both sides. Do I just press the shaft out to replace the bearings?

    No idea. Do you need access to a press?

    Just bought one last night. I've lived long enough without one, tired of borrowing Bob's.

    File this under "now you know"

    If you lightly press this end of the shaft, the shaft comes out of the adapter easily (just don't drop it out the bottom)

    Then you can take out this big aluminum bearing holder and press the bearing out of the holder and replace it.

    Underneath my bearing holder was an unacceptable amount of funk and debauchery.

    I replaced the bearing inside the bearing holder and it's all back together now. Pretty easy really.

    Do the SM420 and Dana 18 share oil through the adapter?
