To grease or not to grease a bronze oil lite input shaft bushing???

As mentioned, oil and grease.

If there's enough clearance to let the grease slip past the input shaft...you'll have other more pressing issues and will be taking it apart shortly regardless. Besides....
The parts that don't like oil are on the other side of the flywheel....grease and oil are magical things but they can't teleport through an inch of solid metal.
