Use the following formulas to determine if you need to replace the bushings or the pins:

• If the inside diameter of the bushing is greater than the original inside diameter of the bushing plus 1 mm (0.04 inch), replace the bushing.

• If the outside diameter of the pin is less than the outside diameter of the new pin minus 2 mm (0.08 inch), replace the pin.
