| 1 . | General. |
| A. | This procedure gives instructions to assemble the turbine center frame assembly (TCF) (35-015 , 72-00-02) (SIN 92500) for SB 72-0121 engines. Refer to Figure 1001. |
| NOTE: |
|
| B. | This procedure starts with the TCF in the 9429M60 roll-over stand with the 11C4559 bracket set installed. |
| C. | This procedure also includes the oil supply tube (01A-620) (SIN 443B1) or (01A-620B) (SIN 443B1) or (01A-620C) (SIN 443B1), air flow check, No. 4 bearing sump pressure test in the No. 4 bearing support housing (15-150) (SIN 01403), oil tubes in the struts, and installation of the exhaust gas temperature (EGT) probes in the TCF. |
| D. | Install protective covers on the spare assemblies only. |
| E. | Install all bolts with the heads up and/or forward unless specified differently. |
| WARNING: |
|
| F. | Before installation, make sure that all rabbet and flange mating surfaces are free of foreign material and raised metal. Clean the flanges and threads of studs with C04-002 Stoddard solvent, C04-003 acetone, or C04-035 isopropyl alcohol. |
| G. | Keep a minimum clearance of 0.125 inch (3.18 mm) between each tube, tube-hose, and hose outside diameter (OD) and the adjacent hardware. |
| H. | All clock positions are aft looking forward (ALF), unless specified differently. |
| WARNING: |
|
| I. | Apply C02-058 lubricant to the bearing (friction) surfaces and the threads of bolts that attach loop clamps for easier assembly. |
| (1) | Use a minimum quantity of C02-058 lubricant necessary for assembly. After assembly, remove the remaining lubricant with a clean C10-182 cloth. |
| J. | Loosely attach tubes, hoses, and manifolds to support hardware until the part or system is completely installed. Make sure that the installed tube, hose, manifold, or system is in the correct position before you torque the nuts, bolts, or tube fittings to the specified torque value. |
| K. | Make sure that you install new preformed packings. You cannot install used preformed packings. |
| WARNING: |
|
| L. | Apply C02-019 engine oil or C02-023 engine oil to preformed packings and lead-in chamfers. |
| M. | Be careful with the components of the No. 4 cylindrical roller bearing (No. 4 roller bearing) (15-091) (SIN 01400). The inner race of the No. 4 roller bearing is a loose part. Make sure that the inner race has the necessary protection for handling damage and corrosion. Refer to TASK 70-14-00-620-003 (HANDLING OF BEARINGS) and TASK 70-60-01-620-002 (PRESERVATION OF ANTIFRICTION BEARINGS) . |
| N. | Keep the roller bearing components (rollers, cages, inner races, and outer races) as a set by serial number. The roller bearing is a matched assembly. Do not mix serviceable roller bearing components with the components of different serial numbers. |
| O. | Follow the instructions to safety parts with safety wire, safety cable, cotter pins, or tab washers. Refer to TASK 70-11-00-400-001 (FASTENER RETENTION PROCEDURES) . |
| P. | The torque values given in this procedure are the actual torque to apply to the fastener. If a torque multiplier is used, do the necessary calculations to find the specified torque, the value that appears on the scale or dial of the torque wrench. Refer to TASK 70-51-00-400-004 (TIGHTENING PRACTICES AND TORQUE VALUES) . |
