ARMY TM 9-6115-464-34 AIR FORCE TO 35C2-3-445-2 NAVY NAVFAC P-8-624-34 Section Ill. REMOVAL AND INSTALLATION OF MAJOR COMPONENTS 2-5. GENERAL. a. The engine and generator are rigidly bolted together at the engine flywheel housing. This assembly is mounted on the skid base at three points, the front engine trunnion and the two generator feet. Rotation and cooling of the generator is accomplished by a blower and coupling disc assembly which is bolted to the engine flywheel. This arrangement allows the engine and generator to be removed as an assembly or independently of each other. b. To remove the engine, it is first necessary to remove the radiator and shell assembly and disassemble the front housing assembly, rear housing assembly, and relay table (including relay table components, see Section XII, 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 relay table with the two side brackets can be removed as a unit by removing four bolts at base of side brackets and disconnecting wiring harness. Prior to loosening the bolts which couple the generator housing to the engine flywheel housing, the engine supporting bracket must be installed between the engine rear lifting bracket and the center support assembly. d. In rare cases, it maybe beneficial to remove the engine and generator as an assembly. To accomplish this, the housing assembly must be disassembled completely (a combination of the disassembly of sub-paragraphs b. and c. above) and the center support assembly removed. The lifting mechanism must be so arranged as to support both the engine and the generator to avoid undue stress on the engine-generator coupling. 2-6. ENGINE ASSEMBLY REMOVAL AND INSTALLATION. a. Removal. (1) Refer to the operator and unit maintenance manual TM 9-6115-464-34, sections 8,9 and 10 and accomplish the following. (a) (b) (c) (d) (e) (f) (g) (h) Drain engine lubricating and cooling systems. WARNING To avoid short circuits which could damage equipment or injure personnel, always disconnect negative battery cable before performing maintenance on the electrical system. Failure to observe this warning could result in servere personnel injury or death by electrocution. Remove radiator, radiator hoses, shell assembly, and shutter assembly. Remove front housing, doors and top panel. Disconnect fuel lines to fuel strainer, filter assembly, secondary fuel filter, and remove day tank. Drain hydraulic sump and disconnect hydraulic lines to hydraulic pump assembly (precisegenerator sets only).
