71 SO-TOOLCT PROCEDURE BELOW, <br /> FOR 7150-TOOL,SEE PAGE 8 7154-TOOLCT <br /> FAIR 7'1513-TOOLC,SEE PAGE 9 <br /> STEP 9C: INSERT 715{�TOOLCT OVER INLET TUBE <br /> To install the 71 SO-TOOLCT(sold separately)over the 774 <br /> inlet tube,first loosen the thumb screws,so the tool can <br /> pass freely over the inlet tube flange. Align the slot on <br /> the tool with the key on the inlet tube and insert the <br /> tool down. See Figure 9C. Tip to stop dimension must <br /> be 1-3116"to 1-114" <br /> Loosen Figure i 1C <br /> thumb land tightens STEP 12C: DRILL HOLES <br /> screws <br /> Tool Slot thumb screws <br /> With the inlet tube and 715D-TOOLCT in place,carefully <br /> r _....... drilla 3116"diameter hole in the upper tube using the <br /> �` - '•t' :�', r: ',.. hole in the 715 <br /> O-TOOLCT as a guide.

If no hole is drilled return to step 91C <br /> and check the stop dimension. If a hole is drilled <br /> - 'f through the inlet tube or into the screw hole the assem- <br /> bly is not salvageable. Drill(2)more holes in the two <br /> Inlet remaining guide holes. <br /> Tube <br /> Key aI<> <br /> Figure 9C Figure]OC <br /> STEP 1 OC: TIGHTEN THE 71 SO-TOOLCT � <br /> Ensure that the tool seats flat against the top of the inlet <br /> tube. To prevent vertical movement of the tool during Rrtilthrough upper tube only <br /> drilling,hand tighten the thumb screws againstthe up- <br /> per drop tube. See Figure 1 QC. <br /> STEP 11C: PREPARE DRILL AND BIT <br /> Confirm that the stop on the 3116"drill bit supplied Figure 12C <br /> with the 71 SO-TOOLCT is in the correct position before <br /> drilling. The stop is factory installed at a distance be- <br /> tween 1-3116"to 1-114"from the tip with the 71 SO- <br /> TOOLCT. If the stop is not at the correct position it must <br /> be fixed before drilling. <br /> CAUTION:if the drill stop is not in the proper loca- <br /> tion failure of a pressure decay leak test may result. <br /> iD <br />
