1/ Dimensions are in inches.
2/ Metric equivalents (to the nearest .01 mm) are given for general information only.
3/ Metric equivalents are in parentheses.
4/ Except the lip thickness is .25 inch (6.35 mm) and tapped holes .138-32UNC-2B.
5/ Except for tapped holes, .164-32UNC-2B in the input (1) flange.
6/ Except for clearance holes of .167/.179 dia in the output (2) flange.
7/ Input flange (1) is M3922/53-003 (8/), and the output and coupled flanges (2 and 3) are M3922/59-008. All
three flanges have threaded holes .164-32UNC-2B.
8/ MIL-DTL-3922/54 and MIL-DTL-3922/55 flange specification sheets are inactive for new design and no
longer used, except for replacement purposes.
