1.4 Lubricant viscosities and refill capacities
1.4.1 Lubricant viscosities for ambient temperatures
Proper oil viscosity grade is determined by the minimum outside temperature while the machine is started
and while operated.
To determine the proper oil viscosity grade, refer to the minimum column in the following table.
This information reflects the coldest ambient temperature condition for starting and for operating a cold
machine.
Refer to the maximum column in the table to select the oil viscosity grade for operating the machine at the
highest temperature anticipated.
Use the highest oil viscosity allowed for ambient temperature when starting the machine.
Machines operated continuously, should use oils having higher oil viscosity in final drives and in
differentials.
Oils with higher oil viscosity will maintain the highest possible oil film thickness.
Consult a dealer if additional information is needed.
