I made up a quick bearing map if anyone wishes to use it while measuring their clearances.

It's pretty straight forward, but you will have to size the image to fit on one sheet of printer paper, and print out 3 copies.

1 copy for crank journals
1 copy for rod/crank housing bores
1 copy for rod/crank housing bores with bearing thickness taken into account.

You can write all of your measurements right on the paper, and circle whichever description you are measuring.

If you want to get really fancy, you can use 3 sheets just for the crank journals to determine if there is any taper.
Left , right, and center.
