Borg Warner Transfer Box: Description and Operation
TRANSFER BOX

DESCRIPTION AND OPERATION
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.
