Common Information

TASK 72-32-10-440-001-B00 No. 3 Bearing Internal Gearbox, And Support Assembly - Assemble, Assembly-001

General

This TASK gives the procedure to assembly the No. 3 Bearing Internal Gearbox and Support Assembly.

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 70-41-00-400-501 and SPM TASK 70-41-02-400-501.

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

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

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 the SPM TASK 70-64-02-640-501.

For cupwasher installation, refer to the SPM TASK 70-42-04-400-501.

The abbreviation Intf shows an interference or tight fit. This causes REJECT IF MORE THAN to become REJECT IF LESS THAN. The abbreviation Clear shows a clearance fit.

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 Figure for a sectional view of the No. 3 Bearing Internal Gearbox and Support Assembly.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

    NOTE
    The clearance let you freely turn the HP Compressor front shaft by hand when you measure backlash of the bevel gears.
    Move the No. 3 Bearing Seal Assembly rearward to make clearance between the No. 3 Bearing Seal Assembly and the No. 3 Bearing Seal Seat.
    NOTE
    The lifting spacer is installed in TASK 72-32-20-440-001-A00 (ASSEMBLY-001) and TASK 72-32-20-440-001-B00 (ASSEMBLY-001).

3. 1. Turn the HP Compressor front shaft clockwise until it becomes tight. Read the indication of the dial indicator. Identify the indicated value as DA.
  2. Turn the HP Compressor front shaft counterclockwise until it becomes tight. Read the indication of the dial indicator. Identify the indicated value as DB.
  3. Calculate the difference between the values DA and DB. This difference is the backlash of the gears. Identify the calculated value as BLA.
4. 1. Calculate the minimum allowable backlash BL min and the maximum allowable backlash BL max.
    BL min (mm) = (LASH A + LASH B + 0,46) x 1,4.
    BL min (in.) = BL min (mm)/25.4.
    BL max (mm) = (LASH A + LASH B + 0,56) x 1,4.
    BL max (in.) = BL max (mm)/25.4.
    Where:
    LASH A - Refer to SUBTASK 72-32-20-220-051 in TASK 72-32-20-440-001-A00 (ASSEMBLY-001) and TASK 72-32-20-440-001-B00 (ASSEMBLY-001).
    LASH B - Refer to Step.
5. Make sure that the backlash BLA measured in Step is between the minimum allowable backlash BL min. and the maximum allowable backlash BL max.
6. If the backlash BLA is not in the limits, replace the flat adjusting washer and the adjusting washer - PTO until the backlash BLA is in the limits.
7. Remove the backlash fixture from the No. 3 Bearing, the Internal Gearbox and the Support Assembly.
8. Attach the No. 3 Bearing Seal Assembly to the No. 3 Bearing Seal Support with the nine bolts "NO.3 BEARING,ROTOR CENTRE & SUPPORT ASSY (72-32-20,01-140). Torque the bolts to 85 lbfin to 105 lbfin (10.00 Nm to 12.00 Nm).
9. Attach the Gearshaft Bearing Housing to the No. 2 Bearing Support with the four bolts No. 3 Bearing, Internal Gearbox, And Support Assembly (72-32-10,01-110) which are removed in Step. Torque the bolts to 85 lbfin to 105 lbfin (10.00 Nm to 12.00 Nm).
10. Remove the No. 3 Bearing Internal Gearbox and Support Assembly from the work stand.
