2. Loosen and remove the six (6\ 1/4-20 x 1 inch socket head cap screws [16]
from the flanged end of the load housing.
Note:
Use a 3/16 inch Allen wrench.
Note:
As shown in Figure 2, the outer conductor assembly may
now be easily removed.
3. Remove the input center conductor assembly [11] or [13] by pulling it out
of the load housing (Figure 3 on page 13).
4. Carefully remove any remaining pieces of the resistor.
Note:
Normally, at this stage of the disassembly, the outer flow
tube will remain with the load housing. Restore it to this position after
inspection and cleaning if it should come out.
5. Inspect the inside of the load housing for any apparent damage. See
“Inspecting the Unit” on page 13.
6. Pull out the inner flow tube.
7. Inspect the inner flow tube carefully for broken pieces.
8. Grasp the projecting hub of the resistor cap assembly [10] firmly.
9. Pull the projecting hub straight off with a strong even force.
10. Wash all the inside portions of the three assemblies thoroughly under
clear running water (i.e., input section, load housing, and water chamber).
11. Replace the resistor Models 8745/8746 Termaline Load Resistor cap
assembly in the water chamber.
12. Push the resistor firmly to the bottom.
Installing a Replacement Resistor
1. Insert replacement resistor [1] into the resistor fitting of the input center
conductor assembly to test its tightness.
Note:
The resistor should not have to be forced into the fitting,
but it should be quite snug. If the resistor is loose in the fitting, press
the slotted finger contacts of the fitting together slightly and try the
resistor again.
2. Continue closing the ends of the resistor fitting until a snug fit is obtained.
3. Bottom the resistor in the fitting.
4. Insert the resistor and the input center conductor assembly into the load hous-
ing with the resistor still in place in the resistor fitting. (Figure 2 on page 12).
5. Replace the outer conductor assembly and the six 1/4-20 x 1 inch socket
head cap screws.
6. Stand the load on end with the RF input connector down.
7. Place the inner flow tube inside the resistor.
8. Lower the inner flow tube until it reaches the resistor fitting.
9. Gently move and twist the inner flow tube until it seats in the bottom of
the resistor fitting.
10. Continue the same procedure as given in "Replacing the Resistor" on
