Engine System, Diesel 82Service Manual – SW8000Engine OilCheck the engine oil level when the machine is parked on a level surface and the engine is cool. Change theengine oil and oil filter after the first 50 hours of operation, then every 200 service hours after that. Use CF,CF-4 or CG-4 oil meeting API specifications and suited temperatures.* Important: Refer to the Diesel Lubricating Oil Note below for further diesel oil recommendations.Refer to the engine manufacturer’s service manuals for oil capacities and additional engine specifications.Replace the oil filter with every oil change.Temperature Range Oil WeightAbove 77 °F (25 °C) SAE 30 or 10W-3032 °F to 77 °F (0 °C to 25 °C) SAE 20 or 10W-30Below 32 °F (0 °C) SAE 10W or 10W-30* Diesel Lubricating Oil Note:With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for usewith a low-sulfur fuel used in on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total base number. If theCF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.FuelLubricatingOil classLow sulfur(0.5 % ≥) High sulfur RemarksCF O O Refer to Kubota Diesel Engine Workshop ManualCF-4 O XCG-4 O XO = Recommended X = Not RecommendedEngine CoolantChecking Engine CoolantCaution! Do not remove the radiator cap when the engine is hot.To check the engine coolant level, open the engine cover and observe the coolant level in the coolant overflowtank. If the level is low, add a 50/50 mix of water and the recommended type antifreeze. Clean the radiatorand oil cooler exteriors every 150 hours by washing with low-pressure water or using compressed air.High-pressure water will damage the radiator..
