Common Information

TASK 72-00-32-050-006-B00 LPC/Intermediate Case Module Components - Remove The Fuel Temperature Thermocouple, Removal-010

General

This TASK gives the procedure to remove 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 item number.

Apply the approved CoMat 10-058 PENETRATING OIL before the removal of threaded parts. Let the parts soak before removal.

Discard all rubber seal rings removed in this procedure.

Remove and discard the lockwire before the plug is disconnected.

The thermocouple removed in the procedure must have its maintenance completed, as given in the Toshiba Component Maintenance Manual (73-35-15).

Seal all openings when the plug and components are disconnected to prevent contamination from unwanted material.

NOTE

To identify the consumable materials refer to the PCI.

Procedure

    1. SUBTASK 72-00-32-040-080 Remove the Fuel Drain Plug

    1. Refer to Figure.

    2. WARNING

      DO NOT LET ENGINE FUEL STAY ON YOUR SKIN FOR A LONG TIME. FLUSH THE FUEL FROM YOUR SKIN WITH WATER. THE FUEL IS POISONOUS AND CAN GO THROUGH YOUR SKIN AND IN TO YOUR BODY.

      Remove the lockwire from the fuel drain plug Fuel Cooled Oil Cooler (FCOC) (79-21-43, 01-147).

    3. Remove the fuel drain plug with sealing ring Fuel Cooled Oil Cooler (FCOC) (79-21-43, 01-149) and drain the fuel in to an applicable container.

    4. Discard the sealing ring.

    2. SUBTASK 72-00-32-030-064 Disconnect the Electrical Connector (Pre SBE 73-0071 and Pre SBE 71-0183)

    1. Refer to Figure.

    2. Disconnect the electrical connector of the EEC harness EEC Fan Harness (71-51-41, 01-005) from the FCOC fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100).

    3. SUBTASK 72-00-32-050-089-A00 Remove the Fuel Temperature Thermocouple (Pre SBE 73-0071 and Pre SBE 71-0183)

    1. Refer to Figure.

    2. Remove the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) that attach the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100) to the FCOC.

    3. Remove the thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100) with the packing FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-120).

    4. SUBTASK 72-00-32-050-089-B00 Remove the Fuel Temperature Thermocouple (SBE 73-0071 and SBE 71-0183)

    1. Refer to Figure.

      2. Disconnect the terminal connectors from the FCOC fuel temperature thermocouple. Refer to Figure.

      1. Remove the four nuts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-130 and FUEL TEMPERATURE THERMOCOUPLE 01-140) and disconnect the thermocouple harness from the thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100).

      2. Remove and refit the thermocouple securing bolts one at a time.

      3. Remove the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) that secure the thermocouple and disconnect the harness ground connectors.

    3. Remove the two bolts FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-110) that attach the fuel temperature thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100) to the FCOC.

    4. Remove the thermocouple FUEL TEMPERATURE THERMOCOUPLE (73-35-15, 01-100) with the packing FUEL TEMPERATURE THERMOCOUPLE (73-35-15,01-120).
