INTRODUCTION

Maintenance, when properly performed, ensures an item of equipment will

perform the mission for which it is designed. Personnel responsible for the

proper maintenance of the M992 Ammunition Carrier must be knowledgeable and

properly trained to accomplish the maintenance and repair of such equipment

that plays a critical role in support of the U.S.

Army artillery firing

missions. As a Self-propelled Field Artillery System Mechanic, MOS 63D, you

are ultimately responsible for ensuring the APU of the M992 Ammunition

Carrier is capable of performing the mission for which it was designed.

PART A - INTRODUCTION TO THE M992 CARRIER, AMMUNITION,

TRACKED

The M992 Carrier, Ammunition, Tracked is a field artillery ammunition

support vehicle and is comparable, in terms of speed, mobility, and

survivability, to the M109A2 and M110A2 family of artillery weapons that it

supports.

The M992 is a full-tracked, self-propelled, diesel powered

vehicle and is highly mobile and maneuverable. The vehicle transports 155mm

artillery projectiles and charges from ammunition depots and supply points

to the howitzers in field locations. The M992 features ammunition handling

equipment (AHE), which includes a hydraulically-operated conveyor, stacker,

and projectile rack assemblies which have a stowage capacity of 90 155mm

The Auxiliary Power Unit is another feature of this vehicle.

The APU

supplies enough power to operate the electrical system of its parent vehicle

and the electrical system of a supported vehicle by use of slave cables and

receptacles. The APU also powers the primary hydraulic pump that supplies

hydraulic fluid to all hydraulic circuits. Without the use of the APU, the

ammunition handling aspect of the M992 Carrier would be seriously reduced

due to a decrease in electrical and hydraulic power.

There are some

differences in vehicles depending on
