Usage:
Lubricants recommended for use in these engines are identified by the sub-headings that follow. Careful attention to the proper selection will add to the performance, economy and life of your engine.
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.
Crankcase Lubricating Oils
Use oils which meet engine Service Classification CD (MIL-L-2104C). These are additive-type oils approved for use in Caterpillar Diesel Engines.
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 level gauge (dipstick) before starting. If the oil will flow off, the oil is fluid enough to circulate properly.
