The abbreviations listed below follow S.A.E. J754 nomenclature. The classifications follow S.A.E. J183 classifications. The MIL specifications are U.S.A. Military Specifications. These definitions will be of assistance in purchasing lubricants.Engine Oils (CD or CD/TO-2)
Use oils that meet the Engine Service Classification CD (MIL-L-2104D) or Caterpillar Tractor Co. CD/TO-2 Classification.Consult the "EMA Lubricating Oils Data Book," Form SEBU5939, for a listing of CD oil brands.The percentage of sulfur in the fuel will affect the engine oil recommendations. If the fuel has over 0.5% sulfur content, the CD engine oil must have a TBN of 20 times the percentage of fuel sulfur (TBN as measured by the ASTM D-2896 method).Higher TBN values are essential to retard the corrosive damage to metal engine parts.Your oil supplier should be able to furnish the correct oils.Hydraulic Implement System (WGF)
Use only water-glycol fluids (WGF) with blends of water, selected glycols and special additives. The fluid is fire resistant if the water content is properly maintained.
Water-glycol fluid must not be mixed with petroleum base oil. If the system becomes contaminated with petroleum based products, shut down the machine immediately. Oil contamination mixed with water-glycol will cause a sludge that plugs filters. Also, oil will decrease the effectiveness of the fluid for fire resistance.Water content must be maintained in the area of 40%. Avoid mixing commercially available water-glycol fluid brands if possible, since properties do vary. Your fluid supplier can furnish information regarding the necessary tests for proper maintenance of the fluid being used.Contact your Caterpillar dealer for proper procedure to flush and clean the system.
Hydrostatic Transmission Oils (HYDO)
Use Engine Service Classification CC (MIL-L-2104B), CC/SF (MIL-L-46152B), CD (MIL-L-2104D) or industrial-type hydraulic oils that are certified by the oil supplier to have antiwear, antifoam, antirust, and antioxidation additive properties for heavy duty use.Lubricating Grease (MPG)
Use Multipurpose-type Grease (MPG). Multipurpose-type grease which contains 3% to 5% molybdenum disulfide is preferred. NLGI No. 2 Grade is suitable for most temperatures. Use NLGI No. 1 or No. 0 Grade for extremely low temperatures.
