Pry the jaw in order to press the cutting edges of the upper jaw against the cutting edges of the lower jaw. Check the clearance between the upper jaw and the lower jaw. Use a feeler gauge or another appropriate measuring tool. Measure the gap on the side of the jaw that is shown in the above illustration. Determine a shim pack for this side of the jaw. The clearance between the cutting edges should not exceed 1 mm (0.0394 inch).
Determine the shim pack for the remaining gap on the other side of the jaw. The clearance between the jaws must not exceed 0.5 mm (0.0197 inch).
Remove the pin bushing and lift the upper jaw in order to install the shims. Install the pin bushing. Recheck the gap between the hinge of the jaw. If the clearance in the jaw is not within the specification, install more shims accordingly.
Recheck the clearance between the cutting edges. If the clearance is not within the specification, an adjustment will need to be made. The shims behind the cutting edges may be altered in order to make this adjustment. If the shims for the cutting edges cannot be adjusted, the shims for the hinge of the jaw will need to be readjusted.

After the adjustments have been made, install the six bolts that secure pin bushing (2) to lower jaw (1) .
