This is a drawing change notice document for engineering modifications to PC 3 (Housing Assembly) on Sheet 3 of drawing 6557926D. The document specifies ten discrete changes to dimensional tolerances, datum references, and geometric control callouts affecting the receptacle assembly.

The modifications include: deletion of a 1.90 reference dimension in Zone F6; updating the 1.25 dimension to 0.756 +/- 0.030 with measurement point relocation in Zone F6; removal of Datum C from True Position callouts for 0.0623/0.0625 holes in Zone F3; deletion of True Position tolerances to multiple datums for receptacle threads in Zone E3; replacement of 2x 1.90 dimensions with 2x 1.406 +/- 0.030 with measurement point adjustment in Zone B5; deletion of 0.020 parallelism tolerance to Datum C in Zone B5; removal of True Position tolerances in Zone A5; deletion of basic dimensions 1.125 in Zone A4 and 1.625 in Zone B4; and deletion of Datum C reference in Zone B3. These changes simplify the geometric control framework and adjust dimensional requirements for the housing assembly component.

All changes are to PC 3 (Housing Assembly) on SH 3 of 6557926D

1. Zone F6: Delete (1.90) Reference dimension

2. Zone F6: Update 1.25 dimension to 0.756 +/- 0.030 and move the bottom measurement point for the dimension upward from the back of receptacle threads to the step in the receptacle body

3. Zone F3: Delete Datum C from True Position callout for the 0.0623/0.0625 holes

4. Zone E3: Delete True Position of 0.030 to Datums A/B/D for the receptacle threads

5. Zone B5: Replace 2x 1.90 dimension with 2x 1.406 +/- 0.030 and move top measurement point for the dimension downward from back of receptacle threads (Datum C) to the step in the receptacle body (located between current Datum C and the weld between the receptacle and the frame).

6. Zone B5: Delete 0.020 parallelism to Datum C

7. Zone A5: Delete True Position of 0.060 to Datum D/C/E and 0.005 to Datum D

8. Zone A4: Delete 1.125 basic dimension

9. Zone B4: Delete 1.625 basic dimension

10. Zone B3: Delete Datum C
