(6)Carefully push the 11C4412   LRU fixture aft and away from the AGB.
(7)Lower the 9446M93   jack stand.
(8)Insert a lift eye into the threaded boss on the top of the VFSG. Refer to Figure 512. Attach a lift strap and hoist to the VFSG.
CAUTION:
MAKE SURE THAT THERE IS A SMALL QUANTITY OF TENSION ON THE HOIST BEFORE YOU LOOSEN AND REMOVE THE STARTER GENERATOR CRADLE (ITEM 6).
(9)Loosen and remove the starter generator cradle (item 6) of the 11C4412   LRU fixture from around the VFSG.
WARNING:
ALWAYS USE APPROVED EQUIPMENT AND PROCEDURES TO LIFT PARTS. STAY OUT FROM BELOW LOADS. IF THE PARTS ACCIDENTALLY MOVE OR FALL, THEY CAN CAUSE AN INJURY OR KILL YOU.

D.A.Alternative Procedure. Remove the VFSGs (65-010) (SIN C00A0) from the AGB (01-010 , 72-00-05) (SIN 03800) as follows:
(1)If not assembled, install the starter generator cradle (item 6) of the 11C4412   LRU fixture on the 9471M12   jack stand and attach it to the adjustment screw. Hand-tighten the adjustment screw. Refer to Figure 510.
WARNING:
ALWAYS USE APPROVED EQUIPMENT AND PROCEDURES TO LIFT PARTS. STAY OUT FROM BELOW LOADS. IF THE PARTS ACCIDENTALLY MOVE OR FALL, THEY CAN CAUSE AN INJURY OR KILL YOU.
CAUTION:
DO NOT LET THE WEIGHT OF THE VFSG TO REST ON THE AGB DRIVESHAFT. THE VFSG MUST BE FULLY SUPPORTED WITH THE 11C4412 LRU FIXTURE UNTIL THE TENSION BOLT IS LOOSENED AND THE QAD RING IS DISENGAGED. DAMAGE TO THE AGB DRIVESHAFT CAN OCCUR.
(2)Slowly push the 11C4412   LRU fixture forward below the engine and aft of the AGB, and align it below the center of the VFSG.
(3)Adjust the 9471M12   jack stand as necessary to support the VFSG.
(4)Attach the starter generator cradle (item 6) around the VFSG and push it into the heat exchanger cradle (item 2) or (item 19) of the 11C4412   LRU fixture.
(5)Loosen the tension bolt to turn the QAD ring counterclockwise (CCW) until the VFSG is disengaged. Refer to Figure 511.
CAUTION:
MAKE SURE THAT YOU DO NOT DAMAGE THE SPLINES OF THE VFSG OR THE AGB WITH EXCESSIVE SIDE-TO-SIDE MOTION.
(6)Carefully push the 11C4412   LRU fixture aft and away from the AGB.
(7)Lower the 9471M12   jack stand.
(8)Insert a lift eye into the threaded boss on the top of the VFSG. Refer to Figure 512. Attach a lift strap and hoist to the VFSG.
CAUTION:
MAKE SURE THAT YOU DO NOT MOVE THE VFSG FORWARD AND AFT, WHEN THE VFSG IS IN CONTACT WITH THE ENGINE GEARBOX. EXCESS SIDE-TO-SIDE MOVEMENT CAN CAUSE DAMAGE TO THE INPUT SEAL.
(9)Loosen and remove the starter generator cradle (item 6) of the 11C4412   LRU fixture from around the VFSG.
WARNING:
ALWAYS USE APPROVED EQUIPMENT AND PROCEDURES TO LIFT PARTS. STAY OUT FROM BELOW LOADS. IF THE PARTS ACCIDENTALLY MOVE OR FALL, THEY CAN CAUSE AN INJURY OR KILL YOU.
(10)Operate the hoist and move the VFSG away from the 11C4412   LRU fixture and on a table or another work area.
(11)Remove and discard the performed packing (01-010 , 71-00-02) (SIN C00N0) from the packing groove on the splined shaft at the front of the VFSG.
(12)Do Subtask 72-00-02-030-754 (paragraph 3.D.A.) again to remove the other VFSG from the AGB.

(1)Loosen and remove the 24 bolts that attach the QAD rings (15-010 , 71-00-02) (SIN C00V0) or (15-011 , 71-00-02) (SIN C00V0) to the AGB. Refer to Figure 513.
(2)Remove the QAD rings (15-010 , 71-00-02) (SIN C00V0) or (15-011 , 71-00-02) (SIN C00V0) and QAD gaskets (15-025 , 71-00-02) (SIN C00V7) from the AGB.
NOTE:
Do not remove the QAD gasket from the QAD ring. The QAD gasket is stuck with an adhesive to the forward surface of the QAD ring. If it is damaged (unserviceable) it will need to be replaced before reinstallation of the QAD rings.
