Revnaster Thrust Bearing and flange  setup

The Revmaster propeller flange and their unique thrust bearing setup shown above. No "shrink-fit" prop flange to break your crankshaft or to come loose causing your propeller to depart from your aircraft  Since the thrust load is absorbed by the thrust bearing on the propeller shaft next to the propeller, the crankshaft journals are not being pulled or pushed, or otherwise highly stressed, by the hundreds of pounds of thrust produced by the propeller. Other VW-based engine conversions use the main bearing on the flywheel end of the engine as their "thrust bearing",  on the opposite end of the engine where the propeller is mounted !!
