Fluid Type Specifications
LubricantsIt is of the utmost importance that the correct lubricant is used in each respective component, only use recommended oils.
The oil in the transfer case is subject to significant stress in the hypoid gear, the oil used is of the best quality and gives low friction, which means that the temperature of the oil is maintained at the correct level.
The fluid used in the differential clutch is a unique product. As the fluid is used to cool and lubricate the clutch pack its friction properties are very important. The control module calculates the viscosity of the fluid in order to compensate for differential clutch application. This is based on the use of a fluid with known and specific properties.
The final drive gear places particular demands on the properties of the oil, partly due to the hypoid gear and partly due to the limited slip differential clutch (if fitted). The oil is equipped with an additive to regulate the friction in the limited slip differential clutch's disc pack.
