Common Information

TASK 72-00-50-420-005-A00 LPT Module - Install The LPT Module Components, External Harnesses, And Tubes, Installation-007

General

For lockwire data and procedures refer to the SPM TASK 70-42-05-400-501.

Transportation covers/blanks must be removed immediately before the installation of components and tubes.

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.

For standard torque data and procedures refer to the SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

Special torque data is identified with the symbol * after the torque value.

Special assembly tolerances are included in this procedure.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-129 ANTI-SEIZE PASTE A anti-seize paste, pure Ni-special, unless other lubricants are referred to in the procedure.

To identify, lubricate and install seal rings refer to the SPM TASK 70-44-01-400-501.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL air drying enamel to any damaged surface protection, joint flanges and attach parts. Use the correct color of air drying enamel. Refer to the SPM TASK 70-38-21-380-501.

The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.

Refer to the V2500 Illustrated Tool and Equipment Manual (ITEM), Pub.ref.ITE-V2500-1IA, for the illustrations of the special tools given in this procedure.

Do not remove the special plastic caps from the electrical connectors until immediately before they are installed. This will give protection from unwanted fluids and materials.

NOTE

Special tools are identified in the procedure by the tool primary number.

      1. Measure the clearance between all the different harnesses and the engine parts:

      1. The general clearance must be a minimum of 0.250 in. (6.35 mm).

      2. A minimum clearance of 0.100 in. (2.54 mm) is necessary between the Exhaust Gas Thermocouple harness/Junction Box, and the tubes, in an area between clip points 5526 and 5547. Refer to Figure.

      3. To check the clearance, push the harness with a light pressure of the thumb then release. The harness must spring back and give the minimum clearance. The harness must not move through the adjacent clips (refer to Step or Step).

      4. The harness can touch the smooth parts of brackets if the harness is clipped to them. The harness must be held so there is no movement between the harness and the bracket.

      5. Adjust the harnesses (if necessary) to get the minimum clearance and torque the clip position nut or bolt to 36 to 45 lbfin (4 to 5 Nm).

    26. SUBTASK 72-00-50-210-072 Visually Inspect the Electrical Backshells and Cable Clamps

    1. Refer to Figure.

    2. Make sure that all the applicable connectors, backshells and cable clamps are secure.

    3. Make sure that all the applicable backshells and cable clamps are safetied with CoMat 02-126 LOCKWIRE. Refer to the SPM TASK 70-42-05-400-501.
