The transmission case, engine and front axle support are bolted together to form a rigid unit.

■

Front Axle & Wheels

The 4WD front axle is a center-pivot, reverse Eliot type.

The front wheel drive mechanism is incorporated as a part of the axle.

The drive power of the front wheels is taken from the rear transmission and transmitted to the

differential in the front axle where the power is divided into right and left and to the respective final

cases.

In the final cases, the transmitted revolution is reduced by the level gears to drive the front wheels.

The 4WD mechanism with level gears provides wider steering and greater durability.
