Phenolic Bearing Drag
I'm restoring a Supertiger .15
I found a pair of new bearings with the phenolic rings on both sides.
After assembling the lower end of the engine there is simply too much resistance to turning.
Can the phenolic rings be pried away to relieve the drag...or are they holding the balls in place...?
If the plastic rings are just dust shields, then I will try removing them with the hope that this will reduce drag.
If I have to, I will convert these bearings to "full complement" style where no retainer for the balls is used...[but that is a PIA to do].
