Common Information
TASK 72-40-00-430-003 HP System Module - Install The No. 4 Bearing And Rear Compartment Parts, Assembly-003
General
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 SPM TASK 70-41-00-400-501 and SPM TASK 70-41-02-400-501.
Special torque data and assembly tolerances are included in this procedure.
Special torque data is identified with the symbol * after the torque value.
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.
To identify, lubricate and install seal rings refer to SPM TASK 70-64-02-640-501.
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.
Transportation covers/blanks must be removed immediately before the installation of the components.

Refer to Figure.
Remove the cover from the No. 4 bearing support ENGINE-NO.4 BEARING SUPPORT ASSEMBLY (72-42-31, 01-010).
NOTE
The No. 4 bearing inner and outer ring and rollers are a serialized set that must be kept together as a set in each engine build.Install the IAE 1P16469 Heater 1 off to the No. 4 bearing support. Attach the heater to the IAE 6F10027 Heater control unit 1 off and heat the support to 345 deg F to 355 deg F (174 deg C to 179 deg C).
NOTE
Make sure the "X" mark on the No. 4 bearing outer race is at the 12 o'clock position of the No. 4 bearing suppport. The dowel pin on the support is at the six o'clock position.When the temperature of the parts has cooled sufficiently, install the IAE 1P16104 Cover 1 off to the No. 4 bearing support.

Install the No. 4 bearing outer race retaining nut ENGINE-NO.4 BEARING LOCK AND NUT (72-42-32, 01-020) to the No. 4 bearing support.

CAUTION
WHEN USING THE IAE 1P16035 Hand wrench THE ACTUAL TORQUE WRENCH READING WILL BE LESS THAN THAT GIVEN BELOW. SEE THE STANDARD PRACTICES MANUAL.Put the IAE 1P16035 Hand wrench 1 off in place on the nut and, with a standard torque wrench, torque the nut to 1900 lbfin to 2100 lbfin (214.671 Nm to 237.268 Nm). Loosen the nut to 0 lbfin (0 Nm) and then torque to 1900 lbfin to 2100 lbfin (214.671 Nm to 237.268 Nm) again. Remove the wrench from the nut.
NOTE
A gap is permitted between the fixture ring and the support outer flange.Lift the IAE 1P16145 Crimp fixture 1 off with a hoist and position over the assembly. Look to see if the jaws are rotated away from the base stop. Look to see if the locator has been retracted. Lower the fixture to the No. 4 bearing support. Hold fixture to the support with the three cap screws and washers. Tighten by hand only.
NOTE
Fixture may be turned to obtain a positive location in nut slot. The base of the fixture is slotted for visual verification of the locator in the nut slot.Attach the IAE 1F10026 Hydraulic hand pump 1 off to the fixture and actuate to crimp the keywasher. Hydraulic pressure setting should be 3000 psi (20684.3 kPa) to crimp the keywasher in eight places.

Install the No. 4 bearing seal spacer ENGINE-NO.4 BEARING SEAL SPACER (72-43-12, 01-010) (with the smooth OD down) on to the HP compressor rear hub. Spacer must touch the front seal seat.
SUBTASK 72-40-00-430-076 Install the No. 4 Bearing Front Seal Seat and the No. 4 Bearing Seal Spacer
Refer to Figure.
NOTE
Do not remove the heater unit until temperature of the bearing outer race is stabilized at 345 deg F to 355 deg F (173 deg C to 179 deg C).
Use the latest revision of the IAE 1P16469 Heater. The latest version of the heater is equipped with heat shield which minimizes the heat transfer to the HP compressor rear hub.
The heating process of the outer race will take about 30 minutes.
Install the IAE 1P16469 Heater 1 off to the No. 4 bearing support and No. 4 bearing outer race. Attach the heater to the IAE 6F10027 Heater control unit 1 off and set the controller to 350 deg F (176 deg C). Heat the bearing support and outer race. The temperature at the outer surface of bearing support adjacent to the bearing retaining nut must not exceed 400 deg F (204 deg C).

CAUTION
IF A HOT OIL TANK WAS USED TO HEAT THE BEARINGS, DO NOT LET THE BEARINGS TOUCH THE BOTTOM OF THE HOT OIL TANK. A HEAVY SCREEN OR SOME RODS ATTACHED 3 IN. (76 MM) ABOVE THE BOTTOM OF THE TANK WILL KEEP HOT OIL ON ALL SIDES OF THE BEARING.
CAUTION
IF YOU USE AN INDUCTION HEATER FOLLOW THE MANUFACTURERS INSTRUCTIONS. DO NOT LET THE BEARING TEMPERATURE GET MORE THAN 250 DEG F (121 DEG C).After the bearing outer race stabilizes at 350 deg F (176 deg C), heat the No. 4 bearing inner race and rollers to 240 deg F to 250 deg F (116 deg C to 121 deg C). Use a hot oil tank for 20 minutes or an induction heater for heating the inner race and rollers.
NOTE
The No. 4 bearing inner and outer race and rollers are a serialized set that must be kept together as a set in each engine build.
The inner race and rollers must be installed within 30 seconds after removing heater from No. 4 bearing support.

CAUTION
THE No. 4 BEARING INNER RACE AND ROLLERS ARE HOT.
CAUTION
CLEAN THE SURFACE OF THE DRIFT THAT CONTACTS WITH THE BEARING. DO NOT USE A MALLET TO SEAT THE BEARING IF IT DID NOT SEAT ALL THE WAY DOWN WHEN INSTALLED.Install the No. 4 bearing inner race and rollers with the puller groove up over the HP compressor rear hub to seat on the last installed No. 4 bearing spacer. Use the IAE 1P16470 Drift 1 off to install the inner race against the spacer.
