71 SO-TOOLCT PROCEDURE BELOW, <br /> FOR 71 SO-TOOL,SEE PAGE 8 71 SO-TOOLCT <br /> FOR 71 SO-TOOLC,SEE PAGE 9 <br /> O <br /> STEP 9C: INSERT 71 SO-TOOLCT OVER INLET TUBE <br /> To install the 71 SO-TOOLCT(sold separately)over the <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 1-3/16"to 1-1/4" <br /> Loosen Figure 11 C <br /> thumb Hand tighten STEP 12C: DRILL HOLES <br /> screws Tool Slot thumb screws <br /> With the inlet tube and 71 SO-TOOLCT in place,carefully <br /> drill a 3/16"diameter hole in the upper tube using the <br /> hole in the 71 SO-TOOLCT as a guide. The drill stop is <br /> X\6 j positioned so it will bottom out against the tool after <br /> o� I the bit has drilled through the upper drop tube. If the <br /> h� I stop is positioned wrong either no hole will be drilled, <br /> or a through hole could potentially be drilled through <br /> the inlet tube. If no hole is drilled return to step 11 C <br /> and check the stop dimension. If a hole is drilled <br /> _�. 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 o <br /> I <br /> Figure 9C Figure 10C <br /> STEP 10C: 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 Drill through upper tube only <br /> drilling,hand tighten the thumb screws against the up- <br /> per drop tube. See Figure 10C. <br /> STEP 11C: PREPARE DRILL AND BIT <br /> Confirm that the stop on the 3/16"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 1-3/16"to 1-1/4"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 /> 10 <br />
