ARMY TM 9-6115-464-34AIR FORCE TO 35C2-3-445-2NAVY NAVFAC P-8-624-34Section Ill. REMOVAL AND INSTALLATION OF MAJOR COMPONENTS2-5. GENERAL.a. The engine and generator are rigidly bolted together at the engine flywheel housing. This assembly ismounted on the skid base at three points, the front engine trunnion and the two generator feet. Rotation andcooling of the generator is accomplished by a blower and coupling disc assembly which is bolted to the engineflywheel. This arrangement allows the engine and generator to be removed as an assembly or independently ofeach other.b. To remove the engine, it is first necessary to remove the radiator and shell assembly and disassemble thefront housing assembly, rear housing assembly, and relay table (including relay table components, see SectionXII, Chapter 3). Engine accessories may either be removed or remain on the engine during removal.c. To remove the generator, remove the rear housing assembly with cooling grille as a single unit. The relaytable with the two side brackets can be removed as a unit by removing four bolts at base of side brackets anddisconnecting wiring harness. Prior to loosening the bolts which couple the generator housing to the engineflywheel housing, the engine supporting bracket must be installed between the engine rear lifting bracket andthe center support assembly.d. In rare cases, it maybe beneficial to remove the engine and generator as an assembly. To accomplishthis, the housing assembly must be disassembled completely (a combination of the disassembly ofsub-paragraphs b. and c. above) and the center support assembly removed. The lifting mechanism must be soarranged as to support both the engine and the generator to avoid undue stress on the engine-generatorcoupling.2-6. ENGINE ASSEMBLY REMOVAL AND INSTALLATION.a.
