TM 5-6115-584-12 NAVFAC P-8-622-12 TO-35C2-3-456-1 TM-05682C-12 (3) Fuel Pump Assemblies (Three) (see figure 3-14). Inspect fuel pumps (1) for dents or other phys- ical damage. Check for leaks especially around hose assembly fittings (2). Check that fuel pumps are se- curely attached to mounting bracket (3) and that mounting bracket is securely attached to bracket sup- port on skid-base. Inspect electrical leads to fuel pumps to see that wires and connectors are not broken, frayed, or damaged. Check that connectors are tightly connected. Check that cap (4) on auxiliary fuel pump inlet is securely in place when unit is not being run from auxiliary fuel supply, (4) Fuel Hoses. Inspect fuel hoses (2, 3 and 4, figure 3-13) for leaks or physical damage. Check to see that fuel hose fittings are securely tightened in place. b. Service. On ASK equipped generators, remove fuel filters access door. (1) Fuel Filter Assemblies (see figure 3-13). Daily before operation, open drain valves (1) and drain water and sediment from filter assemblies. (2) Fuel Strainer Assembly. Daily, before and after operation, open drain valves (1) and drain water and sedi- ment from strainer assembly (11). Figure 3-14. Fuel Pump Assembly 3-20 Change 7 Figure 3-15. Control Cubicle Support Assembly 3-21. CONTROL CUBICLE SUPPORT ASSEMBLY, SPEED CONTROL AND ENGINE CONTROL WIRING HARNESS. a. Inspect. (1) Vibration Mounts (Four) (see figure 3-15). Inspect vibration mounts for deterioration or physi- cal damage. Inspect mounts to see that they are free of dtrt, fuel, or oil. Check to see that mounts are securely attached to control cubicle support on skid- base. If mounts are faulty, refer to higher level of maintenance. (2) Engine Control Wiring Harness Assembly. On ASK aquipped generator, open or remove all access doors. Inspect wiring harness for broken or frayed wires. Check for wires with damaged or deteriorated insulation. Check that all connectors and terminals are ciean and tight. (3) Speed Control Assembly (see fiiure 3-16). On ASK equipped generators lift motor speed control flap. Inspect to see that speed control is firmly attached to unit. Check that speed control moves in and out freely. If speed control is loose, refer to higher level maintenance.
