Drivetrain-Transfer Case
The transfer case is manufactured by New Process Gear Division of New Venture Gear
Company. It is identified as model NV 125.
It incorporates a planetary gear set and chain to provide the torque split and all wheel drive.
The output torque of the transmission is applied to the planetary carrier of the gear set. The
rear drive shaft is connected to the annulus gear and the front drive shaft is connected to
the sun gear through the chain drive.
As the output shaft of the transmission turns, the planetary carrier rotates, causing the
planetary gears to drive the sun gear and annulus gear.
A torque split of 68% rear/ 32% front is provided through the gearing of the planetary set.
