SECTION 4 SERVICE AND PREVENTIVE MAINTENANCE 4.1 INTRODUCTION This section covers service for the generator set and general engine servic. Refer to the Kubota engine workshop manual (refer to section 1.1) for other engine servicing. WARNING Beware of moving V-belt and belt driven components. c. Turn filter (item 3) counter-clockwise and remove. Check and clean. d. To install reverse steps 1 through 3. 5 3 4.2 PREVENTIVE MAINTENANCE SCHEDULE A tabular listing of the recommended preventative maintenance activities and schedule is provided in Table 4-1. 4.3 BATTERY SERVICE When replacing the battery, note if the unit was supplied with a matt in the battery tray. If so equipped, the matt must also be replaced. 4.4 ENGINE SERVICE AND COMPONENTS 4.4.1 Priming The Fuel System The unit is equipped with a mechanical fuel lift pump, mounted on the engine next to the injection pump. The fuel system is a closed circuit which will require bleeding if loss of fuel has occurred. To fill and bleed the system, do the following: a. Turn bleed valve (Red, see Figure 1-3) counterclockwise until fully opened. b. Turn the top of the manual plunger (see Figure 4-1) counter-clockwise to unlock it then, rapidly hand pump the manual plunger until a positive pressure (resistance) is felt, which will indicate fuel flow. c. Depress and turn the top of the manual plunger clockwise to lock in place. d. Start engine. (Refer to section 2.3). e. When engine is running properly, turn bleed valve clockwise until fully closed. 4.4.2 Servicing Fuel Pump Internal Filter Due to foreign particles in the fuel and wax as a result of using the wrong grade of fuel or untreated fuel in cold weather, the internal fuel filter may become plugged or restricted and the engine will loose capacity. The filter must be cleaned on a regular schedule. Quality of fuel will effect filter cleaning schedule (refer to section 4.2). a. Turn nut (item 1) counter-clockwise to loosen and remove . b. Remove banjo fitting (item 2) and let it hang loose, making sure to keep copper rings (item 4) for replacement. 1 1. Nut 2. Banjo 3. Filter 4 2 4. Copper Rings 5. Manual Priming Pump Figure 4-1. Mechanical Fuel Pump 4.4.3 Fuel Filter The full flow filter is located on the generator set frame (see Figure 1-2). To renew, remove the filter with a filter wrench, pre--fill the new filter with fuel, lightly oil gasket with lube oil and replace by hand. 4.4.4 Cooling System The radiator must be clean, externally and internally, for adequate cooling. The fan belt must be adjusted periodically to provide maximum air flow (refer to paragraph 4.4.5). To service the cooling system, do the following: a. Remove all foreign material from the radiator coil by reversing the normal air flow. Compressed air or water may be used as a cleaning agent. It may be necessary to use warm water mixed with any good commercial dishwasher detergent. Rinse coil(s) with fresh water if a detergent is used. b. Drain coolant completely by opening drain-cock and removing radiator cap. CAUTION Never pour cold water into a hot engine. c. Close drain-cock and fill system with clean, untreated water to which three to five percent of an alkaline base radiator cleaner should be added; six ounces (dry) = 151 grams to one gallon (3.8 liter) of water. 1 4-1 T-266
