TM 9-6115-604-34 NAVFAC P-8-633-34 (1) Inspect gasket surfaces for damage that would prevent proper sealing. Repair damaged gasket surfaces in accordance with rebuilding procedures only, paragraph 6-10. or replace the subassembly. (2) Inspect all threaded holes for damage. Repair damaged threads in accordance with rebuilding procedures only, paragraph 6-10, or replace the subassembly. (3) Inspect all capscrews for thread damage. Repairs lightly damaged threads by chasing. Replace severely damaged or stripped capscrews. d. Repair. Replace any subassemblies found to be defective in accordance with step c, above, or Troubleshooting, Chapter 2, Section 11. e. Reassemble. CAUTION To avoid damage to the speed switch SS1/SS2/SS3 or governor components, be sure the speed switch SS1/SS2/SS3 gears are engaged, and the drive tangs on the governor plunger and weight carrier are aligned horizontally before the gasket surfaces are brought together. Turn drive shaft while tightening the capscrews to be sure binding does not o: cur. If binding occurs, disassemble and determine the cause before proceeding with assembly. (1) Using a new gasket (30, Figure 6-5), install the fuel pump housing (29) on the mainshaft, cover, and governor assembly (31), and secure with capscrews (20, 21, and 22), lockwashers (23, 24, and 25), and washers (26, 27, and 28). Cross tighten the capscrews to 9 to 11 pound-feet (12 to 15 newton-meters). (2) Install shutoff valve assembly (18) with a new preformed packing (19) using the capscrews (16) and lockwashers (17). Tighten the capscrews to 9 to 11 pound-feet (12 to 15 newton-meters). CAUTION To avoid damage to the gear pump assembly, turn the drive shaft while tightening the capscrews to be sure binding does not occur. If binding occurs, disassemble and determine the cause before proceeding with assembly. (3) Using a new gasket (15), install the gear pump assembly (14) on the fuel pump housing (29), and secure with capscrews (12) and lockwashers (13). Cross-tighten the capscrews to 11 to 13 pound-feet (15 to 18 newton-meters). (4) Using a new preformed packing (11), install the damper assembly (10) with capscrews (7), lockwashers (8), and washers (9). Cross-tighten the capscrews to 11 to 13 pound-feet (15 to 18 newton-meters). (5) Install the actuator (4) as follows: (a) Ensure that the plug (85, Figure 6-11) and preformed packing (86) are securely seated in the fuel pump housing (6) cavity. Refer to paragraph 6-10, step e. (b) Test the actuator (4, Figure 6-5) by using a jumper wire to connect one terminal of the actuator to a source of 24 V dc current, such as the generator set batteries. Connect the other terminal to ground. A distinct click should be heard when current is supplied to and removed from the actuator terminals. (c) Lubricate the preformed packings (6) with clean engine lubricating oil, such as MIL-L-9000 or equivalent, and install the gasket (5) on the actuator (4). (d) Insert the actuator (4) and gasket (5) into the cavity in the fuel pump housing (29) until the actuator flange is approximately 3/8 inch (9.53 mm) from the fuel pump housing. (e) Using the palm of the hand, firmly push the actuator (4) into the cavity in the fuel pump housing (29). Simultaneously rotate the actuator approximately 30 degrees in a clockwise direction until the flange of the actuator contacts the fuel pump housing. 6-10
