TM 9-6115-604-34 NAVFAC P-8-633-34 WARNING Use of slings, chains, or lifting hoists not rated for the weight of the engine assembly may result In Injury to personnel and damage to equipment. Lifting gear must be rated for 15,000 pounds (6300 kg), minimum. (24) Rig the engine assembly for lifting. See Figure 2-5 and Figure 2-6. There are four lifting brackets mounted to the cylinder block between the cylinder head assemblies. Using locking lifting hooks on the brackets, actuate the hoist enough to take the slack out of the lifting chains, but do not lift the engine at this time. (25) Prepare an engine rebuild stand (3375955 or equivalent) for receipt of the engine. WARNING To minimize potential falling hazard, dear the area of personnel and other equipment when attempting to lift heavy equipment. (26) See Figure 2-5. Remove hexagon head capscrews (16), lockwashers (17), hexagon head capscrews (14), lockwashers (15), and hexagonal nuts (10), lockwashers (12), and hexagonal nuts (13) securing the engine to the rear and front engine supports (6 and 1). Hoist engine so that engine is free of front and rear engine mounts. (27) Remove hexagonal nuts (5), lockwashers (4) and hexagon head capscrews (2) and bevel washers (3) to remove front engine support (1). (28) Move hoist slowly in forward direction until engine flywheel housing dears generator flex plates and hub. CAUTION Take care when moving hoist In forward direction so that engine oil pan does not contact skid ban cross member on which front engine support is mounted. (29) Raise hoist until engine oil pan dears skid base cross member and move in forward direction until engine is dear of generator set, and secure on engine rebuild stand. Install suitable protection over engine flywheel housing, conduit box, and all other exposed equipment to protect from the elements. b. Install. This procedure covers installation and alignment of the engine. (1) Remove hexagonal nuts (9, Figure 2-5), lockwashers (8) and hexagon head capscrews (7) securing rear engine supports (6) to skid base and remove from mounting pads for future use. (2) Remove the ac and dc conduit above the generator in accordance with paragraph 4-35 of the Operator and Organizational Maintenance Manual. Do not remove ac/dc lights. (3) Remove roof panels 5 and 6 (see Figure 2-2) above the generator in accordance with paragraph 4-13 of the Operator and Organizational Maintenance Manual. (4) Remove conduit box cover from rear of generator. See Figure 2-7. (5) Remove capscrews (5, Figure 2-8) and lockwashers (6), and remove generator cable exit enclosure (4). (6) Disconnect cannon plug on battery charger BC1. (7) Rig overhead crane or hoist with minimum load capacity of 6,000 pounds (2722 K) and minimum height clearance of 150 inches (3810 mm). See Figure 2-9 and connect the lifting rig to lifting lugs on generator housing. Take up slack from hoist but do not lift generator at this time. (8) See Figure 2-4. Remove the hexagon head capscrews, hexagonal nuts, and lockwashers from the generator mounting feet. WARNING Use of chains and hoists not rated for the weight of the generator may result In Injury to personnel or damage to equipment 2-28
