Lubrication

Lubrication

Internal lubrication of the transfer gearbox is provided by a low pressure, plunger-type oil pump mounted on the rear of the intermediate shaft. Oil pick-up is through a strainer in the transfer box sump. From the pump, oil is supplied through the intermediate shaft to the epicyclic gear set. The differential and Morse chain are partially immersed in oil and lubricated as the components rotate. The VCU is a fully sealed unit and does not require separate lubrication.
