Packing Rod Repair

You may replace the packing rod as individual parts or as an assembly. The assembly is pre-adjusted at the factory.

Before installing the fluid packing rod into the gun barrel, make sure the internal surfaces of the barrel are clean. Remove any residue with a soft brush or cloth. Check the inside of the barrel for marks from high voltage arc- ing. If marks are present, replace the barrel.

To assemble the individual parts:

1.Place the packing nut (26e) and seal (26b**) on the fluid rod (26h). Flats on the packing nut must face the back of the fluid rod. The seal o-ring must face away from the packing nut. See FIG. 12.

2.Fill the inner cavity of the spacer (26g**) with dielec- tric grease (40). Place the spacer on the fluid rod (26h) in the direction shown. Generously apply dielectric grease to the outside of the spacer.

3.Place the fluid packing (26c**), rod packing (26d**), and housing (26f) on the packing rod (26h) .

4.Lightly tighten the packing nut (26e). The packing nut is properly tightened when there is 3 lb (13.3 N) of drag force when sliding the packing housing (26f) assembly along the rod. Tighten or loosen the pack- ing nut as needed.

5.Install the o-ring (26a**) on the outside of housing (26f). Lubricate the o-ring with non-silicone grease, Part No. 111265. Do not over-lubricate.

6.Install the spring (4) against the nut (E) as shown.

7.Install the packing rod assembly (26) into the gun barrel. Using the multi-tool (37), tighten the assem- bly until just snug.

8.Install the trigger (30) and screws (8).

9.Install the electrode, page 26.

10.Install the nozzle and air cap, page 25.

11.Test gun resistance, page 17.
