I took a picture of a spare (damaged during manufacture) Listeroid connecting rod I had at the airport. I tried to make it contain all the necessary information in one picture.
1) The 2 (two) lube holes on the top bearing shell
2) The "dipper" hole on the bottom that holds the bearings from rotating (where the drill bit is) And why you must be careful not to tighten the dipper against the crankshaft
3) Showing a 13/16th's wrench that fits the nuts
4) The lower bearing shell with just one hole
5) How the "nip" is measured, with a feeler gauge on the left side of this pic (remember the bearings must be installed)
6) I still have not found a torque value for the connecting rod bolts/nuts
And so on. Hope it helps. It's really simple, and the use of just a little care will give great results.
I have hope your crankshaft will be fine with some careful cleanup of old bearing material.
