Re: Rod Bearing Selection is this normal??
Don't go by the letter stamped on the rod. The letter on the rod is it's weight code. So if you had to replace a rod, when you ordered it from Honda you would need to get a "C" weighted one to match the old one.
For rod bearings replacements, cross reference your stamp on the crankshaft, which is crankpin OD (LAABB) for example. Check your rod ID "number" stamp, which is rod ID, "2" for example, and go to the chart.
In my scenario for cylinder number 1, an A crank stamp and a rod number of 2 would require a Green bearing. And that's the process for each other rod.
When you then go to order your hearing you'll notice on a site like Partzilla they designate them by the "letter", which is the clearance range. They stamp the color on them for easier identification upon removal. The letter associated with the color in the chart means nothing as far as you determining which size to get, Honda sells them by the letter, but you seem to be using a non Honda OE manual, as your chart is different than mine. In the OE Honda manual the color is in parentheses on the chart, because you order them by the "letter".
Now, to answer you other question. "Can you just replace with the same color bearing and feel ok about it without plastigauging?? Yes, BUT, I have always plastigauged. In one instance even though the crank was clean with no marring, I had plans to just replace by the colors. But because I just couldn't live with myself if I didn't I plastigauged and the measurement wasn't spot on , so I had to go to the next color (dimension range).
I guess after all that is just take the extra time and gauge them. I hope that helps you out.
