To determine the correct number and thickness of the shims needed, the inside of the outer arm and the outside of the inner arm will need to be measured.
Measure and record the inside dimension of the outer arm as shown [Figure 40-161-36].
Measure and record the outside dimension of the inner arm as shown [Figure 40-161-37].
Subtract the smaller number from the larger number and record the difference.
Measure and record the inside dimension of the outer arm as shown [Figure 40-161-38].
Measure and record the outside dimension of the inner arm as shown [Figure 40-161-39].
Take the measurement in three different locations (Item 1) [Figure 40-161-39] along the length of the arm. Find the average dimension.
Subtract the average (smaller) dimension from the larger dimension and record the difference.
Install the correct number and thickness of shims under the wear pads to center the inner arm inside of the outer arm and obtain 0,0 – 0,5 mm (0.0 – 0.02 in) clearance between the wear pads and inner / outer arm assemblies.
