ATTACHING SWEEP COUPLERS TO SWEEP TUBES
0.25”
• Refer to figure 6.06 during the following steps for an overview of the assembly process.
• Each of the sweep coupler halves (PN 10-1155-01) will have a notch in the mold on one side
marked with silver sharpie. IT IS CRITICAL THAT THESE NOTCHES ARE POINTING TOWARDS THE
SWEEPS OR THEY WILL NOT WORK PROPERLY. See figure 6.07 for the location of the mark. Be
certain that each half of the coupler has the mark facing the sweep tube!
13. Place the coupler halves over the heat shrink on the sweep side of the joint. The flange on the
diverter should still be visible through the heat shrink, as well as the edge of the sweep material. The
non-marked side of the coupler should be placed as close to the edge of the sweep material as possi-
ble, without overhanging, as shown in the cutaway in figure 6.08 where the sweep diverter is high-
lighted in blue.
14. Insert four of the 6-32 x 2” socket head screw (PN 60-0186) with washer (PN 60-0016). Place
the screws so that the threaded portion of the screw is facing downward. BE SURE THAT THE DRAIN
HOLES FOR THE PLASTIC SWEEP TUBE ARE POINTING DOWNWARD BEFORE INSTALLING THE COU-
PLERS.
15. Apply anti-seize to the threads and screw the Nylock nuts on. Tighten using a 5/16” wrench/
socket to turn the nut and the provided 5/64” Allen Key to hold the screw. Tighten enough so that the
clamp is held in place on the sweep/heat shrink. Final tightening will happen once the fiberglass
spreader is installed.
16. Repeat the previous steps on the other side of sweep tube.
