3 . Procedure.
Subtask 72-00-01-040-050
A.Remove the fan stator module from the 11C4490   separation dolly and put it, forward end down, on a clean work surface. Refer to Figure 502 and do as follows:
(1)Attach a clevis and an overhead hoist to the left/right hanger of the 11C4486   fan case ring at the 11:00 o'clock and 1:00 o'clock positions.
(2)Attach an overhead hoist to the 11C3199   lift/turn fixture.
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.
(3)Apply a lift pressure to the fan stator module assembly.
CAUTION:
MAKE SURE THAT THE WHEEL CASTER LOCKS REMAIN LOCKED AT ALL TIMES UNLESS YOU MOVE THE DOLLY. THE WHEEL CASTER LOCKS PREVENT MOVEMENT OF THE DOLLY TO PERMIT SAFE WORKING CONDITIONS.
(4)Disconnect the 11C4490   separation dolly from the fan stator module. Make sure that the wheel casters on the dolly are in the locked position.
(5)Lift the fan stator module off the 11C4490   separation dolly, and move the dolly away from the fan stator module.
(6)Use the two lifts to safely rotate the fan stator module from the horizontal position to the vertical position with the forward end down.
(7)Lower the fan stator module assembly onto a clean work area or six wooden blocks equally spaced with the forward end down.
(8)Remove the overhead hoists from the 11C4486   fan case ring and the 11C3199   lift/turn fixture.
