(2) Install the 3 guide pins, equally spaced, on the forward flange of the fan disk. Install one of the pins in the offset hole.
B. Install the spinner rear cone as follows:
(1) Apply a thin layer of graphite grease (Material No.CP2101) to the threads of the bolts (30).
(2) Safety precautions.
(3) Install the spinner rear cone.
(5) Let the assembly return to the ambient temperature.Then remove the guide pins.
(6) Replace the guide pins (856A3409G01) with the bolts (30) and the washers (10).
(7) TORQUE the bolts (30) to between 115 and 97 lbf.in (1.30 and 1.10 m.daN ).
(8) Do a check of the clearance (gap F34) between the rear edge of the spinner rear cone and the fan blades with a GAGE - SET, FEELER.
5. Close-up(1) Apply a thin layer of graphite grease (Material No.CP2101) to the threads of the bolts (30).
(2) Safety precautions.
WARNING:
USE THERMAL GLOVES WHEN YOU MOVE OR TOUCH HOT OR COLD PARTS. HOT OR COLD PARTS CAN CAUSE INJURY.
(a) Increase the temperature of the aft flange of the spinner rear cone to 60 deg.C (140.00 deg.F) with a GUN - HOT AIR. (3) Install the spinner rear cone.
CAUTION:
TAKE CARE NOT TO LET THE SPINNER REAR CONE FALL WHEN YOU INSTALL IT ON THE FAN DISK. DAMAGE TO THE CONE COULD RESULT.
(a) Install the spinner rear cone (20) on the fan disk forward flange with the offset holes aligned. NOTE: The offset hole in the spinner rear cone is identified by a spherical indentation on its rear flange.
(4) Attach the rear cone to the disk with 3 bolts (30) and washers (10). Make sure it is correctly seated. (5) Let the assembly return to the ambient temperature.Then remove the guide pins.
(6) Replace the guide pins (856A3409G01) with the bolts (30) and the washers (10).
(7) TORQUE the bolts (30) to between 115 and 97 lbf.in (1.30 and 1.10 m.daN )
. (8) Do a check of the clearance (gap F34) between the rear edge of the spinner rear cone and the fan blades with a GAGE - SET, FEELER.
NOTE: This clearance (gap F34) must be measured with blades in the most forward axial position.
NOTE: This clearance (gap F34) must be comprised between 0.012 in. (0.3 mm) and 0.043 in. (1.1 mm).
(9) In case of incorrect clearance, remove the rear cone, and make sure that the fan blades are correctly installed. Subtask 72-21-00-410-050-A ** ON A/C NOT FOR ALL Subtask 72-21-00-869-051-A ** ON A/C NOT FOR ALL
