325F Excavator Machine Systems Boom - Install Caterpillar

Installation Procedure

Show/hide table

When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death.

Note: Make sure that the pin bores in the boom and the pin bores in the upper frame are clean and free of dirt and debris prior to installing the boom in the upper frame.

5. 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 to obtain the required clearance.

6. Use the following table to determine the correct shims (20).
