THEORY OF OPERATION (Contd)

POWERTRAIN

Power Train System Operation: The powertrain components are the same on all models with

exception of turbocharged and non-turbocharged engines and an additional propeller shaft and center

bearing on the M36A2. The major powertrain components of the M44A2 series are as follows:

A FRONT AXLE Transmits power from front differential to front wheels.

B TRANSMISSION Transfers engine power to meet different speeds and power requirements.

C TRANSFER CASE TO FRONT DIFFERENTIAL PROPELLER SHAFT Transmits power from the

transfer case to the front differential.

D TRANSFER CASE Distributes power to front and rear axles.

E UNIVERSAL JOINTS Permit power to be transmitted at slight angles between transmission and

transfer case and between transfer case and differentials.

F TRANSFER CASE TO FORWARD-REAR AXLE PROPELLER SHAFT Transmits power from the

transfer case to the forward-rear differential.

G FORWARD-REAR AXLE Transmits power from forward rear differential to forward-rear wheels.

H FORWARD-REAR AXLE TO REAR-REAR AXLE PROPELLER SHAFT Transmits power from the

forward-rear axle to the rear-rear axle.

I REAR-REAR AXLE Transmits power from rear-rear differential to rear-rear wheels.

J TRANSMISSION TO TRANSFER CASE PROPELLER SHAFT Transmits power from the

transmission to the transfer case.

K ENGINE Transmits power from the transmission to the transfer case.
