Rods face which way?
The small end goes "up".
Bah, ha ha... Sorry, I can't resist being a wise ***. The side of the rod with no chamfer goes against the adjacent rod. The chamfer runs against the counterweight on the crank. I think the cap also has an arrow cast in that points forward, IIRC.
I hope you didn't mix up the rod caps, cuz then you're REALLY screwed!
