Removing bearing shields

[Nat Penton]

Tom , I am using the sealed bearings from Boca, no afterrun oil and do not run dry. 600+ flts and am running "heavy" props, APC 14.5 x 11, 4 blade.

  Nat, Are you using the sealed bearing on the 91FX from Boca? If so do you use any after run or do you just run it dry?
  thanks

    Ed you will get longer service life if you do not remove the shields. I'm assumming this is the same bearing, rubber seals, that I am using on the 91FX. You need to provide adequate crankcase coling.            Nat Penton

      Take a small punch (or your smallest jeweler's screwdriver.)  and pop a tiny hole in the shield (between balls of course). The metal shield will start to deform  from that - then lever the shield out of the bearing either using the hole or an edge exposed from the hole- making. 



      No damage to the bearing this way.

      I have a set of stainless steel shielded bearings for my OS 1.60 and need to remove the shields.  I haven't figured out a way to do it yet without damaging the bearing.  Any ideas?  Special tools?  Help!



      Thanks
