Mounting the fiberglass spreaders
Attach the black fiberglass sweep spreaders (PN 10-1503-21) to the sweep couplers. There is a con-
cave mounting area on each side of the plastic couplers. Position the fiberglass spreader so that the
holes align with the couplers as shown in
figure 12.20
.
When installing the fiberglass spreader, you
will want the spreader to be underneath the plastic coupler as shown in
figure 12.21
.
The loop has
been turned upside down in this picture so you can see the detail. The spreaders will be longer than
the couplers on each side of the loop as shown in
figure 12.22
. This is done on purpose to ensure
plenty of fiberglass material is on each side of the screw.
Insert #10 x 2” pan-head machine screw (PN 60-0156) through each of the coupler halves and the fi-
berglass rod. This screw must be placed so that the Philips head of the machine screw is seated inside
the concave groove on the top coupler as shown in
figure 12.22
and the Nylock nut (PN 60-0014) is
secured against the fiberglass material as shown in
figure 12.21
. The machine screws are longer than
normal by design so that you can get the nut on in the initial stages of the process.
Tighten the Nylock nuts firmly. Be sure to use anti-seize on these screws or they very likely will gall
and have to be replaced. Repeat the above steps for the remaining sweeps.
Figure 12.23
shows the
completed sweep assembly.
