Dave,

If these are "sealed" bearings you can leave the seals on. These are lubricated
for life. If they are only "shielded" you can pop out the shields facing the rear,
when mounted in the engine, on both bearings.

  Yup! I leveraged the gear puller with a wrench, heated the hub slightly with a torch and tapped the end with a mallet and it popped off.

  Thanks! It's in the oven!

  Now, do I leave the seals in the new bearing or not?

    Dave,

    Try a little heat with a torch while you have the tension from the puller
    on the drive washer. The aluminum drive washer will expand more with a 
    little heat then the steel shaft will. If that doesn't work, use the hammer 
    and the heat.  :-)

      I hope you're joking! I just emailed a friend about this and he said, "take your time and think things through before you resort to a hammer." (!)

      Also: I'm using the Boca sealed SS bearing. What was the concensus regarding leaving/removing the seal(s)?

        When it's good and tight, hit the end of the puller screw a good belt with a hammer! The abrupt shock will bust it free.

          I'm replacing the bearing in a Webra 1.45. All of the "difficult" disassembly is done: the circlip, wrist pin etc., but I'm having trouble removing the prop drive hub. I'm assuming this is a press fit and am using a gear puller, but even tightening the tool as much as I can, the hub stays put. Is there a trick to removing it? Thanks, Dave
