TM 9-6115-604-34 NAVFAC P-8-633-34 d. Shutoff Valve. The shutoff valve is an electrically operated solenoid valve; when energized, it allows fuel flow into the engine. When deenergized, the shutoff valve cuts off the fuel flow from the fuel pump, causing the engine to shut down. (1) Disassemble. See Figure 6-10. (a) Remove the coil assembly (7) and shield (9) from valve housing (1) by removing capscrews and washers (6). (b) Discard housing preformed packing (8). Remove spring washer (10) and plate valve (11). (c) Remove knob (2) and remove shaft(5)from valve housing (1). Check the shaft for wear and discard preformed packing (3). (2) Inspect See Figure 6-10. WARNING Compressed air used for cleaning or drying can create airborne particles that may enter the eyes. Pressure shall not exceed 30 psi (207 kPa). Wearing of goggles Is required to avoid Injury to personnel. (a) Clean all parts except coil assembly (7) in dean diesel fuel, regular grade DF2 W-F-800, and blow dry with compressed air. Wipe the coil assembly (7) with a dean dry both. (b) Inspect the plate valve (11), spring washer (10), and valve seat inside valve housing (1) for dirt, wear, bonding separation, corrosion, and deterioration of rubber parts as applicable. Replace as necessary. (c) Check width of the valve seat inside valve housing (1). Replace housing if width is less than 0.015 inch (0.38 mm). (d) With multimeter set to RX100 scale, check the coil assembly (7). Resistance reading should be 30 ± 2 ohms. Replace the coil if it does not meet this specification. (3) Assembly. See Figure 6-10. (a) Install new preformed packing (3) on the shaft (5). (b) Screw the shaft (5) into the valve housing (1) until it comes to a full stop. With depth micrometer set at 0.118 inch (2.997 mm) check distance from top of the shaft (5) to the plate valve (11) seat in the valve housing (1). If necessary turn the shaft (5) out to the required distance as set on the depth micrometer. Without moving the shaft (5) install the knob (2) on the other end of the shaft. (c) Install the valve plate (11) inside the valve housing (1) with its rubber side against the seat in the valve housing. (d) Install new housing preformed packing (8) inside the valve housing (1). (e) Install spring washer (10) on the valve plate (11) with its cavity side up and around the valve locator. (f) Install the shield (9) and coil assembly (7) on the valve housing (1). Tighten the coil screws and washers (6) to 25 to 30 inch-pounds (2.8 to 3.4 newton-meters). e. Fuel Pump Assembly. See Figure 6-11. (1) Disassemble. (a) Note the method of seal wiring for-later reassembly, cut the seal wire, remove the fuel pump seal (1) and discard the seal wire and fuel pump seal. (b) Remove the capscrews (2), washers (3), lockwashers (4), spring pack cover (5), gasket (6), and plug (7). Discard the gasket. (c) Remove the snap ring (8), high speed spring retainer (9), governor spring shims (10), governor idle spring spacer (11), high speed governor spring (12), idle adjust screw (13), dip (14), idle and dip guide (15), adjusting screw washer (16), idling speed spring (17), and idle spring plunger (18). Discard the snap ring. 6-18
