Lubrication Specifications
Crankcase Lubricating Oils
Use oils which meet Engine Service Classification CD (MIL-L-2104D) or CD/TO-2. These are additive-type oils that have been approved for use in Caterpillar Diesel Engines.Consult the "EMA Lubricating Oils Data Book," Form SEBU5939, for a listing of CD oil brands.The proper SAE grade of oil to select is determined by the ambient temperature at which the engine is started and the maximum ambient temperature in which the engine will be operating. See chart for recommended viscosity and temperature range.To determine if the oil in the crankcase will flow in cold weather, remove the oil dipstick before starting. If the oil will flow off, the oil is fluid enough to circulate properly.Lubricating Grease
Use Multipurpose-type Grease (MPGM) which contains 3-5% molybdenum disulfide conforming to MIL-M-7866, and a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures. Use NLGI No. 0 or No. 1 Grade for extremely low temperatures.Recommended Lubricant Viscosities
Air Starting Motor Oiler: Use SAE 10W in all temperatures.Flywheel Clutch Bearing Reservoir: Use SAE 30 in all temperatures. Fuel Specifications
No. 2 fuel oil and No. 2D diesel fuel are recommended for use in Caterpillar Diesel Engines. In extreme cold temperatures use No. 1 fuel oil or No. 1D diesel fuel.In selecting a fuel, note that distillate fuels are especially desirable because the fuel is heated to a vaporous state and condensed, thus eliminating all sediment and residue.There is considerable variation in the composition of fuels distributed under the No. 2 grade classifications. For desirable engine service it is most important to give special attention to cetane no., water and sediment, pour point, cloud point and sulphur content. USE THE LOWEST PRICE DISTILLATE FUEL WHICH MEETS THE FOLLOWING REQUIREMENTS.Water and Sediment 0.1% sedimentCetane No. (PC Engine) 35 minimum(DI Engine) 40 minimumPour Point 10°F (6°C) below ambient temperatureCloud Point No higher than ambient temperatureSulphur Content* Adjust oil change periodGravity 32-40 A.P.I. at 60°F (15.6°C)*See the topic SULPHUR CONTENT. Cetane No: This is an indication of a fuel's ignition quality and should not be less than 35 for the PC engine and 40 for the DI engine. For high altitude operation or cold weather starting, a higher cetane number is required. Water and Sediment: A good clean fuel will contain no more than 0.1% sediment and water. Dirty fuels lead to early filter plugging and in addition can result in the formation of gums and resins reducing filter and engine life. Pour Point: The pour point of the fuel has no effect on engine performance, as long as the fuel is fluid enough to flow from the fuel tank to the engine. The pour point of the fuel should be at least 10°F (6°C) below the lowest atmospheric temperature at which the engine must start and operate. In extremely cold temperatures it may be necessary to use No. 1 fuel oil or No. 1D diesel fuel. Cloud Point: Cloud point is the temperature at which wax crystals become visible and is generally above the pour point of
