The new bronze bearing will be interesting but had I done it I would have pressed it into the connecting rod and kept the slip fit on the crankshaft journal.
My reason for this is twofold.
First, the oil supply is thru the crankshaft journal which directly feeds the bearing surface. This eliminates the need for the multiple holes that feed the outer area of the bearing. Of course, the annular groove in the inside of the bearing is still needed to distribute the oil completely around the sliding surfaces.
Second, the journal velocity in the bore is lower than it will be with the moving surface at the outside of the bearing.
Velocity speed is a definite limit on sleeve bearings and keeping it as low as possible would be a goal in my design.
For what it's worth, the original design of the rod bearing is a "floating" design.
With both the inner and outer surfaces of the bearing moving with a oil film between them and their mating parts, it serves as a cushion to lessen shock that can be imposed on the crank journal and the connecting rod.
This isn't very important for the large steel crankshaft journal but it could be for the rather flimsy aluminum connecting rod.
Anyway, good luck with your projects.
