engine bearings sizes and color code system

[DaRAVENS2K]

I've looked all over for the engine bearings sizes for the F20C and all I can find is the silly color code that doesn't give the actual specs for each bearing thickness. So does anyone have the specs for each color main journal bearing and rod bearings????????

Found this on another Honda site via a Google search. Best confirm with Honda about the accuracy of this info:

CHART COLOR to BEARING THICKNESS

Blue 2.013-2.010 mm 0.0793”- 0.0791”
Black 2.010-2.007 mm 0.0791”- 0.0790”
Brown 2.007-2.004 mm 0.0790”- 0.0789”
Green 2.004-2.001 mm 0.0789”- 0.0788”
Yellow 2.001-1.998 mm 0.0788”- 0.0787”
Pink 1.998-1.995 mm 0.0787”- 0.0785”
Red 1.995-1.992 mm 0.0785”- 0.0783”

Rod bearing thickness by color
Blue 1.510-1.507 mm 0.0594”- 0.0593”
Black 1.507-1.504 mm 0.0593”- 0.0592”
Brown 1.504-1.501 mm 0.0592”- 0.0591”
Green 1.501-1.498 mm 0.0591”- 0.0590”
Yellow 1.498-1.495 mm 0.0590”- 0.0589”

is that for an f20c or b18

I found that on a site for B series, but I was thinking each manufacturer might use the same color codes for thicknesses. That's why I suggested you confirm this with a Honda shop.

Wouldn't one order by thickness of bearing needed rather than order by color?

But the funny thing is that when honda made the color code system for the f20c it was backward of the b18 meaning the thickness is different as well I wanted to know the specs for the f20c not a b18 or b16

Sorry, can't be of much help to you. I've never rebuilt an engine, let alone this one.
Just to clarify, do you have the service manual? It does state the thickness ranges in the specs. Or is this not what you are after?

I don't have a service manual I really should get one tho. and that is what I'm after

Ahhh, I could have given this to you when you first posted had I known that's what you wanted. Now, I'm at work and my manual is at home. I'll get that info to you this evening if no one else gets to it first.

Here's out of my 00/01 Helm manual:

Main bearing to journal oil clearance ...... 0.017 - 0.041 mm (0.0007 - 0.0016 in.) --- Standard or New.
....... 0.050 mm (0.0020 in.) --- Service Limit.

Rod bearing clearance ....... 0.030 - 0.054 mm (0.0012 - 0.0021 in.) --- Standard or New.
........ 0.060 mm (0.0024 in.) --- Service Limit.
