Typical example
Slide the stick cylinder to one side until the stick cylinder makes contact with the boom and the stick. Measure the total clearance between the stick cylinder and the boom at the pin bore. Measure the total clearance between the stick cylinder and the stick at the pin bore. The total clearance of measurement (a) plus measurement (b) must not be more than 1.0 mm (.04 inch) at each pin bore. If the total clearance is less than 1.0 mm (.04 inch), the addition of shims between the stick cylinder and boom or between the stick cylinder and stick will not be required. If the total clearance is more than 1.0 mm (.04 inch), the addition of shims between the stick cylinder and boom or between the stick cylinder and stick will be required.
Remove pin assemblies (2) and (5) , if shims are required. Refer to Disassembly and Assembly, "Stick Cylinder - Remove" in this manual. Install the shims between the stick cylinder and the boom or between the stick cylinder and the stick on the side opposite the retaining bolt for the pin assembly. Install the spacers and pin assemblies (2) and (5) . Install retaining bolts (1) and (6) that hold the pin assemblies in position. Tighten bolts (1) and (6) to a torque of 325 40 N m (240 30 lb ft) .
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine.
