S.S.Bearing- What to Do about it??

[Verne Koester]

Bob,
The general consensus of pilots I talked to at the Nats (many of whom were long time competitors) was that the engine should have less oil, not more. The general idea was that more oil causes the balls to skid instead of roll. However, little or no oil, which was the case with my engine, causes the bearing to deteriorate rapidly. So far, the sealed, EFI bearing has worked just fine.

  Assuming that OS doesn't offer a solution to lubrication of the rear bearing on the 1.40, what other options are available?
      What mods could be made to the crankcase to permit more oil flow back there?
      Would increasing oil content of fuel make any difference?

  If the real core problem is undersizing of the bearing for the load application the motor endures, then a real fix would be a redesign of the crankcase to use a larger and wider bearing.  Pretty unlikely that would happen, I would guess.
      So what's the solution besides keeping the bearing suppliers well-funded??
