MAINTENANCE 20.3 TRANSMISSION, TORQUE CONVERTER, TRANSFER CASE AND OIL COOLER, SERVICE BRAKES AND HYDRAULIC SYSTEM OIL SPECIFICATIONS Komatsu Engine Oil or engine oil meeting American Petroleum Institute (API) performance classification CF-4, CG-4, CF-4/SG or CG-4/SH or MIL-L-2104D or E is recommended. NOTICE: Classification CD, CE, CD/SF or CE/SF oils may be used in areas where CF-4, CG-4, CF-4/SG or CG-4/SH oil is not yet available. 20.4 FINAL DRIVE OIL SPECIFICATIONS Komatsu Gear Lubricant or an equivalent multi-purpose gear lubricant meeting API GL-5 or MIL-L-2105C is recommended. 20.5 DRIVE AXLE OIL SPECIFICATIONS For drive axle oil, use only the recommended oil as follows: SHELL:
DONAX TT or TD CALTEX: RPM TRACTOR HYDRAULIC FLUID CHEVRON: TRACTOR HYDRAULIC FLUID TEXACO: TDH OIL MOBIL: MOBIL 424 Engine oil: SAE 30 API classification CD (Might increase brake noise, but it will not affect durability.) 20.6 DIESEL FUEL SPECIFICATIONS WARNING Never mix gasoline, gasohol and/or alcohol with diesel fuel. Mixing these liquids creates an extreme fire hazard and could lead to an explosion which could result in personal injury or death. WARNING Never remove the fuel tank filler cap or refill the fuel tank while the engine is running or when hot or when the machine is indoors. Fumes are dangerous, a spark or flame could result in a fire or explosion. NOTICE:
The precise tolerances of diesel fuel injection systems demand that the fuel be kept clean and free of contaminates or water. Contaminates or water in the system can cause severe damage to both the injection pump and nozzles. REMARK Below -12 uel will change to wax particles and clog the fuel filters. For best results use Grade No. 1-D diesel fuel in cold weather. For normal service above -10 Grade No. 2-D diesel fuel with a minimum Cetane number of 40 is recommended. The use of No. 2-D diesel fuel will result in optimum engine performance under most operating conditions.
Fuels with Cetane numbers higher than 40 may be needed in high altitudes or extremely low ambient temperatures to prevent misfires and excessive smoke. At operating temperatures below -10 +14 use of lighter fuels can reduce fuel economy. Where a winterized blend of Grade No. 2-D and No. 1-D fuels is available, it may be substituted for Grade No. 1-D fuel. However, it is the supplier's responsibility to provide the fuel for the anticipated ambient temperature. 3-12 WA420-3MC
