Information:
Close the gauge protector valve ( 0 to 40,000 kPa (0 to 5,800 psi) gauge).
Visually inspect the pattern of the fuel nozzle for a uniform spray.Note: For this test, each full stroke of the pump should be performed in less than one second.
Rapidly increase the pressure on the fuel nozzle until fluid sprays from the tip of the fuel nozzle.
Test fluid should spray from the tip of the nozzle in a pattern that is uniform. Refer to Illustration 2.
Check the individual spray orifices for partial plugging.
Use a moderate pump stroke to open the valve of the fuel nozzle.
During the pump stroke, view the individual spray orifices for partial plugging.The test fluid should spray uniformly from all the orifices.If an orifice is plugged or the pattern is distorted, clean the fuel nozzle orifices and repeat this test. Refer to Special Instruction, SEHS8627, "Use of 8S-2245 Nozzle Cleaning Tool Group" for instructions on tool usage and cleaning procedures.Test the Fuel Nozzle for Seal Leakage
Note: Testing for seal leakage is not a requirement for the 104-9450 Fuel Nozzle, 104-9452 Fuel Nozzle, 104-9453 Fuel Nozzle, or the 104-9454 Fuel Nozzle. Do not perform this test on these fuel nozzles.
Illustration 3 g00453789
Typical example of a 7000 Series fuel nozzle
Remove the cloth from the top of the nozzle.
Prior to performing this test, install a new seal washer on purging screw (A) and reinstall the purging screw into the fuel nozzle.
Illustration 4 g00453809
Tighten purging screw (D) or purging screw (E) to a torque of 2.2 0.8 N m (20 7 lb in). Note: Use a 6V-4980 Torque Screwdriver Tool Group to torque the purging screw.
Apply a test pressure of 13,800 kPa (2,000 psi) to the fuel nozzle.Note: Due to the large amount of test fluid that is delivered to the fuel nozzle, hydraulic lock may prevent the nozzle from opening during this test. If a hydraulic lock occurs, slowly loosen the adapter fitting to relieve the pressure on the fuel nozzle valve assembly.If there is leakage at the purging screw, install a new 8C-3234 Screw and a 114-3364 Washer as replacement parts. Retest the fuel nozzle for leaks.Do not use the nozzle if there is leakage that cannot be repaired at purging screw (A), upper seal joint (B), or lower seal joint (C).Returning Fuel Nozzles to Service
Illustration 5 g00453817Prior to returning fuel nozzles to service, install a new seal washer (3) and install a new carbon dam (4) on the fuel nozzle (1).Use 6V-4979 Carbon Seal Installation Tool (2) to install a new carbon dam (4).Table 5 contains part numbers for the replacement of the fuel nozzle seal washers.
