Re: measuring engine bearings
 
ive built quite a few engines and that is defiantly a good read! Thats what i was going to suggest for the bearings, since you have a caliper, you can probably get your hands on a mic as well. This is the most accurate way to ensure your buying the correct sized bearings. I've always used ACLs, but i will use stock color coded bearings next time.

I've had that in my bookmarks since forever ago. Great article but still doesn't explain where to measure and which part of the claw to use.

In that picture, the measurement was taken with the tip and the caliper shows a measurement of .0803 inches.

According to this list,


Main Bearing thickness by color
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”
Pink 1.495-1.492 mm 0.0589”- 0.0587”
Red 1.492-1.489 mm 0.0587”- 0.0586”
none of those bearings = .0803 inches. This is what confuses me.

why dont you just use a plastic gauge from autozone or advanced or napa?

Because it's not accurate.

It gives me the wonderful options of measure from .002 or .015.

I want .017.

Yes, I'm a nit-picky bastard.
