The outside diameter of a camshaft bearing journal is 1.125" and the inside diameter of the installed bearing measures 1.1273”.  How much clearance is there?

Solution:

The amount of clearance is one-half the difference between the inside and the outside diameters.
1.1273" – 1.125" = 0.0023"
0.0023"/2 = 0.00115"
