Did search and even have a Helms but this does not make sense to me. I had a full set of acl bearings but messed one up bad for a rod, so I need to get stock bearings for one rod. Its from a d16a6 crx si block and has a 3 stamped into it the side of the big end. The crank is stamped 2 on one side of the journal and B on the other side of the journal. Now I thought that the rods were just numbered 1, 2, 3, 4 to know which journal they went on and not to determine bearing size. So if someone could tell me what size bearing I need that would be wonderful. The clearance needs to be btw. .008"-.0015" with a service limit of .002. All the other acl bearings were reading .0015".

 

the number stamped on the rod corresponds to the diameter of the rod.
If you have a Helms, the rod bearing code you need to look up is 3B. Match 3 up with B on the selection chart, and it will give you the bearing color that you need to order for that journal combination.

What engine?

 

I too have questions about the chart to identify bearings. I have a 2004 Honda Accord V.6 3.0 6 Speed. Only 2 of the mains have any color at all and 4 of the rod bearings have color. If the journals all are with specs, then why are different bearings required. Its would seem any change in the thickness of rods would cause vibration especially if all the rods weight the same ( or within one gram). These rods have no marks on them whatsoever so identification from the chart is no an option. Sooo, now what? The manual states even with the charts and specific colors chosen, plastic gauge is still to be used. Soooo now What? The block has BBBB the crankshaft has BBAABC and 3234. By the way Honda wants $11.36 for each main half $90.89+tx , $4.19 each rod half $50.78+tx and $36.63 for each ring set $219.78 for rings. 386.75 + shipping Sooo over $400.00 just for these parts not to mention the
