Common Information

TASK 72-40-00-430-006-A00 HP System Module - Install The HPT Assembly (Vertical) - Method 2, Assembly-006

General

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 SPM TASK 70-41-00-400-501, SPM TASK 70-41-00-400-501 and SPM TASK 70-41-01-400-501.

Special torque data and assembly tolerances are included in this procedure.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred to in the procedure.

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

The number for each radial location must be identified in a clockwise direction. Use CoMat 06-153 FELT TIP MARKER, RAPID DRYING or CoMat 06-158 MARKER, EXTRA FINE POINT(BLACK). These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure. Refer to SPM TASK 70-09-00-400-501.

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

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

  2. Install the fixture to the rear flange of the HP Turbine case and the digital indicator rod on the stage 2 turbine hub lug end.
  3. Measure the distance to the lugs on the stage 2 turbine hub at three equally spaced positions.
    At each measurement, add or substract the digital indicator reading to the 1.261 in. (32.0 mm) dimension.
    Average the three measurements.
    The running distance must be 1.251 in. to 1.271 in. (31.78 mm to 32.28 mm).
  4. Remove the checking fixture.
3. 1. Put equal hand pressure on the outer edge of the cover to hold the cover in position.
1. Refer to Figure.
2. 1. Before the gage is used, move the digital indicator to the machine area on the gage and set the digital indicator to zero. The dimension of the indicator rod when the digital indicator is zero is 1.194in. (30.328 mm).
  2. Install the gage to the rear flange of the HP Turbine case and the digital indicator rod on the stage 2 turbine hub lug end.
  3. Measure the distance to the lugs on the stage 2 turbine hub at three equally spaced positions.
    At each measurement, add or substract the digital indicator reading to the 1.194 in. (30.328 mm) dimension.
    Average the three measurements.
    The running distance must be 1.194 in. to 1.214 in. (30.33 mm to 30.84 mm).
  4. Remove the gage.
3. 1. Put equal hand pressure on the outer edge of the cover to hold the cover in position.
