Subtask 72-64-11-350-001
A.Set-up the verticallink to machine the swaged lip of the spherical bearing as follows:
NOTE:
The spherical bearing has swaged lips on the two sides.It is necessary to weaken one of the swaged lips by machining to removethe spherical bearing. It is not important which swaged lip is machined.
(1)Put the base assembly and the verticallink on the machine table. Refer to Figure 901 and do as follows:
(a)Make sure that the vertical link surfaceadjacent to the spherical bearing is perpendicular to the machinespindle to 0.0011 inch (0.03 mm) or less.
(b)Align the machine spindle with theinner diameter (ID) of the spherical bearing to 0.0011 inch (0.03mm) or less.
