Common Information

TASK 72-32-00-430-003 LPC/Intermediate Case Module - Install The No. 3 Bearing, Internal Gearbox And Support Assembly, Assembly-003

General

This TASK gives the procedure to install the No.3 bearing, internal gearbox and support assembly. For other parts of the LP compressor/intermediate case module, refer to TASK 72-32-00-430-000 (72-32-00 ASSEMBLY-00).

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 TASK 70-41-02-400-501.

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

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.

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

The No.1 strut, which is the top position strut of the fan frame assembly, is identified by the five pressure tubes on the strut leading edge.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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

    3. Release the lock pin from the hole in the handle and the hole in the support C of the turnover stand.

    4. Turn the handle to set the fan frame assembly vertical with the front end up.

    5. NOTE

      Make sure that the hole in the support C and one of the eight holes in the handle are aligned. If necessary, turn the handle to align the two holes.

      Reinstall the lock pin into position to lock the handle.

    3. SUBTASK 72-32-00-430-098 Install the Support Assembly (No. 3 Bearing, Internal Gearbox and Support Assembly) into the Fan Frame Assembly

    1. Refer to Figure, Figure, Figure and Figure.

    2. Use CoMat 02-149 DRY ICE to cause the PTO inner seal ring Fan Frame Assembly And Related Parts (72-32-03, 03-050) to be cold, Figure.

    3. Install the PTO seal ring into the PTO guide tube in the No.6 strut of the fan frame assembly.
