Brian Whatcott Altus OK

How do you install Roller Bearings on connecting rods? All the
Roller Bearings used in engines I have ever seen, were on
single cyl engine cranks that could be pressed on from each end.
I would think that any split shell Roller Bearing, would be less
robust than a regular shell bearing in the same application.

Me just wondering........
