Removing bearing shields

[rickwallace45]

As I understand it there's a major difference between SEALED - as in rubber
coated steel seals - -and shielded - as in steel shields that don't provide
any real barrier to liquids etc passing thru. 

I wouldn't remove the seals from sealed bearings, routinely pull at least
one shield from shielded ones before installing them.

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
