NONESafety Requirements
NONEProcedure
Refer to Figure.
Put the fuel nozzle and support assembly onto the IAE 1P16167 Holding plate 1 off and connect to the Power arm vise.
Use an Allen wrench.
Remove the fuel strainer element and/or the metering plug.
Increase the temperature of the oven to 500 deg F (260 deg C).

WARNING
FOR PROTECTION FROM HIGH TEMPERATURES, WEAR A FACE SHIELD AND PROTECTIVE CLOTHING.Put the assembly in the oven.
Use an Allen wrench.

WARNING
WEAR PROTECTIVE GLOVES.
CAUTION
THE FUEL METERING PLUG AND SUPPORT ASSEMBLY ARE A MATCHED SET AND MUST BE KEPT TOGETHER.While the assembly is hot, connect it to the power arm vise. Remove the strainer element or the metering plug
If the wrench does not loosen the strainer element or the metering plug do the following:
Remove the fuel nozzle and support assembly from Power arm vise and IAE 1P16167 Holding plate.
Refer to Cleaning-004 TASK 73-13-41-100-204.
Flush the assembly
SUBTASK 73-13-41-350-051 Remove the Fuel Strainer Element and/or the Fuel Metering Plug
Refer to Figure.

CAUTION
THE FUEL METERING PLUG AND THE SUPPORT ASSEMBLY ARE A MATCHED SET AND MUST BE KEPT TOGETHER.NOTE
Metering plugs are sold with an orifice that is smaller than necessary. It will be necessary to ream out the orifice to the appropriate diameter to meet the flow requirements that are specified in the Testing section.However, it is not permitted to try to adjust for fuel passage coking or blockage by changing the orifice diameter because if the blockage was subsequently removed the nozzle flow would be too high, possibly resulting in increased hot section distress. Service-run nozzles that cannot meet minimum flow requirements after cleaning must be returned to the vendor for replacement or repair.Install the assembly on to the holding plate and secure to the Power arm vise.
Refer to Figure.
Torque the plug to 10 to 20 lbfin (1.13 to 2.26 Nm).
Torque the strainer element to 15 to 35 lbfin (1.70 to 3.95 Nm).
Torque the metering plug and the fuel strainer element into the passage through the fuel inlet fitting
Remove the assembly from the Power arm vise and the IAE 1P16167 Holding plate
Refer to Testing-001 TASK 73-13-41-700-201.
Do the fuel flow test
Refer to Figure.
Put the fuel nozzle and support assembly onto the IAE 1P16167 Holding plate 1 off and connect to the Power arm vise.
Use an Allen wrench.
Remove the fuel strainer element and/or the metering plug
Refer to Cleaning-005 TASK 73-13-41-100-205.
Clean the strainer element and/or the metering plug
Use CoMat 04-010 ACTIVATOR/PRIMER primer T.
Apply primer to threads of the fuel strainer element and the metering plug
Apply compound to threads of the strainer element and the metering plug
Refer to Figure.
Torque the metering plug to 10 to 20 lbfin (1.13 to 2.26 Nm).
Torque the strainer element to 15 to 35 lbfin (1.70 to 3.95 Nm).
Torque the metering plug and the fuel strainer element into passage through the fuel inlet fitting
Remove the assembly from the Power arm vise and IAE 1P16167 Holding plate.
Cure at room temperature for a minimum of 24 hours or bake for 15 to 30 minutes at 215 deg F (101.6 deg C).
Refer to Testing-001 TASK 73-13-41-700-201.
Do the fuel flow test
