Measure the total clearance between the boom and the upper frame at the bore for the boom foot pin. The total clearance of Dimension (a) plus Dimension (b) must not be more than 1.0 mm (0.04 inch). If the total clearance is less than 1.0 mm (0.04 inch), the addition of shims between the boom and the upper frame will not be required. If the total clearance is more than 1.0 mm (0.04 inch), add the correct thickness of shims in order to obtain the required clearance.
Use the following table to determine the correct shims (9).
