The gap to inspect is shown in Figure 1-14 next to the serial number.
Figure 1-14 Gantry Bearing
On most systems, a change in the bearing gap does not cause the gantry to make unusual sounds,
unless the gap is severe. If the gantry is badly damaged and the gap is severe, it can cause
operation issues. Some systems are shipped with shock indicators that must be returned to
Milwaukee.
A severe failure may be seen during installation as a problem rotating the gantry.
