ARMY TM 9-6115-604-12 NAVY NAVFAC P-8-633-12 e. Oil Change Instructions. Change oil every 300 hours of operation or 3 months, whichever comes first. During cold weather operating conditions, change oil more frequently than usual due to increased contamination by dilution and sludge formation. (1) Before draining the oil system, operate the engine until minimum coolant temperature of 160°F (710C) is obtained. Then shut engine off and set MAINTENANCE LOCKOUT switch S100 (1, Figure 2-1) to MAINTENANCE. (2) Remove oil drain cap from skid base fitting, then open engine oil drain valve and allow oil to drain into a container. Refer to Table 3-1 for oil capacity. Refer to Figure 1-2 for oil drain point. (3) Close oil drain valve and install drain plug. Add oil to HI mark on oil level gage or LOW mark on oil sight glass. (4) Set MAINTENANCE LOCKOUT switch S100 (1, Figure 2-1), to OPERATION Start and operate engine for approximately 5 minutes. (5) Stop engine and allow oil to drain back into crankcase before rechecking oil level. f. Oil Filter Service. See Table 3-2 and paragraph 3-2 Service the oil filters by replacing the main and by-pass oil filter elements at intervals noted in Table 3-1. Perform oil filter servicing with the engine not running. Refer to Table 3-1 for quantity, and type of oil filter elements. (1) Replace the spin-on elements (Figure 3-3) of the main oil filters. Fill the filter with lubricating oil and apply a small amount of lubricating oil to the gasket sealing surfaces prior to installation. Tighten by hand until the seal touches the filter head and then tighten an additional one-half to three-fourths turn. (2) Replace the spin-on elements (Figure 3-3) and preformed packing of the by-pass filter assembly. Fill the filter with lubricating oil and apply a small amount of lubricating oil to the gasket sealing surfaces prior to installation. Tighten by hand until the seal touches the filter head and then tighten an additional one-half to three-fourths turn. (3) Run the engine and check for leaks Stop engine and wait 3 minutes. Recheck the engine oil level, add oil as necessary to bring the oil level to HI mark on the oil level gage. g Lubrication of Generator G1 Main Bearing. To avoid accidental engine cranking or startup, which could cause injury to maintenance personnel, place MAINTENANCE LOCKOUT switch S100 in the MAINTENANCE position prior to servicing the generator set. Return switch to the OPERATION position only after completion of service procedures. (1) With the generator set shut down, and the MAINTENANCE LOCKOUT switch S100 In the MAINTENANCE position, wipe clean the filler and drain plugs (refer to Figure 3-4). (2) Remove the filler and drain plugs. (3) Free the drain hole of any hard grease using a piece of wire as necessary. (4) Insert a 1/8 inch NPT grease fitting in the filler plug hole. (5) Using a low pressure grease gun, add approximately 2 1 ounces (59.5 grams) of grease. Refer to Figure 3-2 for proper grease at expected temperature range. (6) Remove the 1/8 Inch NPT grease fittings and Install the filler plug. (7) With the drain plug removed, start the generator set and allow the unit to run for 15 minutes to allow excess grease to drain (8) Stop the generator set, wipe off any drained grease, then install the drain plug. 3-13
