Things wear with use. The 0.002 is if you measure and come up over this number, time for new bushings reamed to size. Might need new wrist pins too.

If you measure .002 on a repair, its time to replace them. If you can feel play between the pin and the rod, they need replacing. Less than two thousandths takes 6 Million Dollar Man hands to feel.
