A.Refer to Figure 901, Figure 902, and Figure 904 for specified dimensions and locations.
NOTE:
The dimensional data identified within this procedure was designed using inches as the base unit of measurement for dimensional values. The conversion to millimeters is rounded to one less decimal digit than inches. For minimum dimensions, converted values are rounded up. For maximum dimensions, converted values are rounded down. To avoid conversion errors, do not reconvert from millimeters to inches.
4 . Setup Information.
None.
5 . Procedure.
