D400E Series II Ejector Truck Caterpillar

The proper lubricant viscosity grade is determined by the minimum outside temperature when the machine is started. The proper lubricant viscosity grade is also determined by the maximum outside temperature while the machine is operated. Use the column that is designated "Min" on the table to determine the lubricant viscosity grade that is required when you start a cold machine and when you operate a cold machine. Use the column that is designated "Max" on the table to select the lubricant viscosity grade for operating the machine at the highest temperature that is anticipated. Use the highest SAE viscosity grade of oil that is allowed for the temperature when you start the machine. In order to maintain the highest possible thickness of oil, machines that are continuously operated should use an oil that has a higher viscosity in the final drives and in the differentials. Consult your Caterpillar Dealer if additional information is needed.

( 1 )	The first choice of oils are of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W20, SAE 0W30, and SAE 5W30. The second choice of oils should be oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W20, SAE 0W30, or SAE 5W30.
( 2 )	TMS exceeds the TO-4M specifications.
( 3 )	TDTO or TO-4 SAE 50 is preferred in most applications, particularly continuous operation. If the ambient temperature is below -15 °C (5 °F), warm up the oil prior to operation. The oil must be maintained to a temperature above -15 °C (5 °F) during operation. If the ambient temperature is below -15 °C (5 °F), perform the procedures in the Operation and Maintenance Manual, "Cold Weather Operation" prior to operating a loaded machine. If the ambient temperature is below -25 °C (-13 °F), consult your Caterpillar dealer for further instructions. Failure to warm up the oil prior to operation will cause damage to the machine.
