h22a bearing selection. help!!
alright well i got my h22a back and it is time for assembly. only i cant figure out the bearings. heres the prob. first the rod bearings. according to the 92 honda service manual i am to check for the numbers that are stamped on each rod then look for the stamps on the crank that corespond to that journal. and use this graph to select color of bearing.
rod Code
1 or 1 2 or 11 3 or 111 4 or 1111
Aor 1 red pink yellow green
journal code B or 11 pink yellow green brown
C or 111 yelllow green brown black
D or 1111 green brown black blue
simple right? well i looked at the numbers on the rods and starting from the timing belt side its 2223. and the journals are bbcc. now u would think that u would use 2 yellow and one green and one brown.
only the ones that came out are all brown except #3 whitch is green.
either way. i bought new eagle rods, and was wondering if the rods are all bored the same. and how do i select bearings. as honda service manual only gives colors not actual thickness?? please help. i wanna make sure this thing is built right. any and all suggestions are appreciated. thanx

I'm interested in your question also.
I can help by providing the color/sizes from the H/F specs thread:

h23 power has good stuff, and now you just need to understand that rod and main bearing clearences need to be checked by torquing everything together with your new friend and savior, plastigauge. it's a stuff that comes in several different sizes, or ranges, and it's used to measure clearences where a gauge won't fit. every inch pound torque wrench should come with it, because it would be crazy to install rods without using both items. your rods need to be measured with bearings installed to determine the clearence between the crank and rod. once you get a measurement, use H23Power's chart to figure out whether you need a thicker or thinner plain bearing to achieve the clearence you want. we're gunning for the right gap for oil to flow evenly through here, so take your time and use the specs in the honda service manual. once the plastigauge is smashed to the width that corresponds to your crank to rod bearing oil clearence, make sure you assembly lube the hell out of everything that rubs and torque it all to spec with your inch pound torque wrench. if you can't tell by now, if you replace the rods, you get to figure out on your own what size bearings to use in each position. none of the initial stock bearings will likely work, especially if you had the crank journals mirror polished or if the crank has any wear on it.
