Common Information

TASK 72-00-32-450-006-B00 LPC/Intermediate Case Module Components - Install The Fuel Temperature Thermocouple, Installation-010

General

This TASK gives the procedure to install the fuel temperature thermocouple.

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha-variants refer to the IPC.

For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-039 ENGINE OIL, unless other lubricants are referred to in the procedure.

For the torque tightening procedures, refer to the SPM and SPM TASK 70-41-01-400-501.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to the SPM .

NOTE

To identify the consumable materials refer to the PCI.

Procedure

    1. SUBTASK 72-00-32-450-099-A00 Install the Fuel Temperature Thermocouple to the Fuel Cooled Oil Cooler (FCOC) (Pre SBE 73-0071 and Pre SBE 71-0183)

    1. Refer to Figure.

    2. Lubricate the FUEL TEMPERATURE THERMOCOUPLE (73-35-15,01-120) packing 1 off with clean CoMat 10-039 ENGINE OIL.

    3. Install the packing to the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100).

    4. Install the fuel temperature thermocouple with packing, to the FCOC.

    5. Install the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110).

    6. Torque the bolts to between 65 and 85 lbf.in (0.73 and 0.96 mdaN).

    7. Connect the 4017KS-A electrical connector to the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100) and torque the connector to 18 * lbf.in (2.0 Nm).

    2. SUBTASK 72-00-32-450-099-B00 Install the Fuel Temperature Thermocouple to the Fuel Cooled Oil Cooler (FCOC) (Post SBE 73-0071 and SBE 71-0183)

      SBE 71-0183: Power Plant - Electrical harnesses - Introduction of production standard EEC harness to suit FCOC fuel temperature thermocouple with stud type thermocouple

      SBE 73-0071: Fuel and Control - Replacement of fuel temperature thermocouple with stud and nut terminations

    1. Refer to Figure, Figure and Figure.

    2. Lubricate the FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-120) packing 1 off with clean CoMat 10-039 ENGINE OIL.

    3. Install the packing to the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100). Refer to Figure.

    4. Install the fuel temperature thermocouple with packing, to the FCOC.

    5. NOTE

      Make sure that the larger studs are at the top of the unit before you tighten the bolts.

      NOTE

      Make sure that the material window is at the bottom of the unit before you tighten the bolts.

      Install the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) and tighten the bolts.

      6. Connect the terminal connectors to the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100).

      1. If the thermocouple is not to be removed, remove and install the thermocouple securing bolts one at a time. Refer to Figure and Figure.

      2. Remove the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) that secure the thermocouple to the FCOC Fuel Cooled Oil Cooler (FCOC) (79-21-43, 01-100).

      3. WARNING

        WHEN YOU USE CoMat 01-002 SOLVENT, DELETED. YOU MUST USE THE NECESSARY PROTECTIVE CLOTHING. DO NOT GET THE SOLVENT ON YOUR SKIN OR IN YOUR EYES. YOU MUST NOT SMOKE WHEN YOU USE THE SOLVENT AS THE VAPOR CHANGES AND BECOMES TOXIC.

        Remove the grease, the fingerprints and the unwanted material from the mating surfaces of the ground terminals and thermocouple earth positions with CoMat 01-002 SOLVENT, DELETED.. Use a clean lint free cloth moistened with the solvent.

      4. Install the harness ground terminal connectors to the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110). Install the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) to secure the thermocouple to the FCOC and torque the bolts to between 85 and 105 lbf.in (10 to 12 Nm). Refer to Figure, view D.

      5. CAUTION

        YOU MUST NOT EXCEED THE RECOMMENED TORQUE VALUES. OVER TORQUING CAN RESULT IN FRACTURE OF THE THERMOCOUPLE STUDS.
