Common Information
TASK 72-32-00-430-002-B00 LPC/Intermediate Case Module - Install The Dowel Pins, Bush, Oil Feed Adapter, Main Oil Distributor, Oil Feed Tube, And Rear Seal Drain Tube, Assembly-002
General
This TASK gives the procedure to install the dowel pins, the bush, the oil feed adapter, the main oil distributor, the oil feed tube and the rear seal drain tube.
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.
To identify, lubricate and install seal rings, refer to the SPM TASK 70-64-02-640-501.
Special torque data and assembly tolerances are included in the 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.
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.
The No. 1 Strut, which is the top position Strut of the Fan Frame Assembly, is identified by the five pressure tubes on the No. 1 Strut leading edge.
