I have a friends cb750 which was a fresh top/bottom build, had the oil lines crossed and seized before ever seeing any miles.
Upon disassembly, everything looks okay except a single rod bearing is toast. The plan is to clean up the crankshaft surface and install a new rod bearing.
I've checked the FSM and am lost in the spec chart, and am hoping someone can help decipher. I've done a few searches which reference different colored bearings... All I pulled out are silver. I'm totally missing something.
Attached is the seized bearing.
I'll post the rod code later today. I didn't record it before buttoning it back up. All work is done in my dusty backyard, so best chances of keeping things clean are to reassemble the cases and side covers, and valve cover of needed, each time I work on it. Fun, right?
Thanks for the help!
Edit: the shell of the bearing has code D5J-A STD
