The factory used the bushing for years. I suspect the only reason for using the bearing was to save on labor costs of drilling the cranks as well as having specific cranks for 4-gear applications. My vote goes with the non-moving part - the bushing.



They used the bearings for years too......think Dakotas,etc. That's the bearing that's in my BB. With that said ....either will work fine,pick one that fits your app.(crank register,etc)and put it together. Mine's been together for many years with the bearing...no problems.
