Procedure

    1. SUBTASK 73-13-41-350-064 Prerequisites

      1. Remove fuel strainer element and metering plug.

      2. Refer to Repair, VRS3458 (Repair-002) TASK 73-13-41-300-002.

      1. Make sure the cleaning and inspections for this repair have been done before you do this repair.

      2. Clean by Cleaning-000 TASK 73-13-41-100-200 and Examine by Inspection-000 TASK 73-13-41-200-400.

    1. SUBTASK 73-13-41-320-006 Machine to Remove the Fuel Inlet Fitting and Insert

    2. Refer to Figure and Figure.

      1. Machine to remove the fuel inlet fitting and insert.

      2. See dimensions in the figure.

    1. SUBTASK 73-13-41-350-065 Remove Debris from Support Assembly Fuel Passage

      1. Back flush the support assembly to remove debris from the fuel passage

      2. Use Comat 10-069 calibration fluid or water.

    1. SUBTASK 73-13-41-130-053 Clean the Support

      1. Ultrasonic clean the support

      2. Clean by Cleaning-003 TASK 73-13-41-100-203.

    1. SUBTASK 73-13-41-230-063 Do a Fluorescent Penetrant Inspection of the Support

      1. Do a fluorescent penetrant inspection of the machined area of the support

      2. Refer to SPM TASK 70-23-05-230-501.

      3. No cracks permitted.

    1. SUBTASK 73-13-41-110-064 Clean the Support, Replacement Fuel Inlet Fitting and Insert

      1. Clean the support, replacement fuel inlet fitting and insert

      2. Refer to SPM TASK 70-11-03-300-503.

    1. SUBTASK 73-13-41-350-066 Prepare, Install and Braze the Replacement Inlet Fuel Fitting

    2. Prepare, install and braze the replacement fuel inlet fitting

    3. Refer to SPM TASK 70-31-14-310-501.

    4. NOTE

      Track welding the fuel inlet fitting to the support is permitted. Track welding the insert to the fuel is permitted but must be removed at final assembly. Use CoMat 03-286 WELDING WIRE.
    1. SUBTASK 73-13-41-210-001 Do an Inspection of the Braze Joint

      CAUTION

      FUEL NOZZLE SUPPORT ASSEMBLY CONTAINS ADDITIONAL CoMat 03-114 BRAZE FILLER METAL 82Au-18Ni BRAZE JOINTS AT THE INNER HEAT SHIELD, INNER AIR SWIRLER AND CENTER BODY. BRAZE PROCESS CONDUCTED BY SPM TASK 70-31-14-310-501 PROCESS WINDOW MUST ENSURE MINIMAL BRAZE FLOW AT THE EXISTING BRAZE JOINTS. WHEN YOU DO A VISUAL INSPECTION OF THE JOINTS, THE JOINTS MUST SHOW 100 PERCENT LINE OF BRAZE AT THE OUTER END OF THE JOINT.
      1. Do a visual inspection of the braze joint.

      2. A complete line of braze must be visible at the outer end of the joint. Too much braze in the fillet at the external end of the joint is acceptable.

      3. Too much braze on other areas of the support or fitting OD beyond the fillet is acceptable, if it is firmly bonded, smooth in appearance, not located on a mating surface and is not more than 0.015 in. (0.38 mm) high.

      4. Too much braze on the conical seat is not acceptable. Refer to repair, VRS3257 (Repair-004) TASK 73-13-41-300-004 Signs of too much braze removal is acceptable, if parent material is not removed.

    1. SUBTASK 73-13-41-260-001 Do an X-Ray Inspection of the Braze Bond

    2. Refer to Figure, Figure and Figure.

      1. Do an X-ray examination of the braze bond.

      2. Area of braze coverage must not be less than 80 percent of the mating portions of assembly.

      3. A complete braze fillet must be present for 360 degrees at the exposed edge of the braze joint. This braze fillet must be free of any voids.

        NOTE

        Single exposure technique shows tangential braze lines which are criteria for judging braze flow within the joint. Refer to Figure.

        NOTE

        X-ray machine procedures can be obtained from the machine manufacturer. The necessary X-ray machine settings must be developed with the machine manufacturer's parameters and by the X-ray inspection method specifications as stated in Table 1 and Table 2 in Figure and Figure. Refer to SPM TASK 70-26-00-260-501.
    1. SUBTASK 73-13-41-110-065 Back Flush Support Assembly

      1. Back flush the support assembly

      2. Use Comat 10-069 calibration fluid or water.

    1. SUBTASK 73-13-41-350-067 Do a Leak Test

      1. Do a leak test with nitrogen.

      2. Test by Testing-001 TASK 73-13-41-700-201.

      3. No leaks permitted.

    1. SUBTASK 73-13-41-350-068 Postrequisites

      1. Install metering plug and fuel strainer

      2. Repair by VRS3458 (Repair-002) TASK 73-13-41-300-002.
