1-2. MAINTENANCE FORMS AND PROCEDURES
Department of the Army forms and procedures used for equipment maintenance will be
those prescribed by DA Pam 738-750 as contained in the Maintenance Management
Update.
1-3. CORROSION PREVENTION AND CONTROL (CPC)
The vehicle has a total service life of 20 years which allows for extended periods of
operation in a corrosive environment. A corrosive environment includes exposure to high
humidity, salt spray, road de-icing chemicals, gravel damage, and atmospheric
contamination. No action beyond normal washing and repair of damaged areas is needed
to control corrosion. To prevent moisture accumulation, drain holes are provided on
structural and sheet metal areas where needed, and stowage boxes are provided with
seals and baffled drains.
Corrosion Prevention and Control (CPC) of Army material is a continuing concern. It is
important that any corrosion problems with the vehicle be reported so that the problem can
be corrected and improvements made to prevent the problem in the future.
While corrosion is typically associated with rusting of metals, it can also include
deterioration of other materials, such as rubber and plastic. Unusual cracking, softening,
swelling, or breaking of these materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using form SF 368 (Product Quality
Deficiency Report). Using keywords such as "corrosion", "rust", "cracking", or
"deterioration" will ensure that the information is identified as a CPC problem.
Form SF 368 should be submitted to the address specified in DA PAM 738-750.
1-4. DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY
USE
Command decision, according to the tactical situation, will determine when the using
organization is to destroy a vehicle. A destruction plan will be prepared by the using
organization, unless one was prepared by a higher authority. For general vehicle
destruction procedures, refer to TM 750-244-6, Procedures for Destruction of Tank-
Automotive Equipment to Prevent Enemy Use (U.S. Army Tank-automotive and
Armaments Command).
1-5. REPORTING EQUIPMENT IMPROVEMENT

Section II. EQUIPMENT DESCRIPTION
1-10. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND
FEATURES
a. Characteristics. The MTVs are a series of 6x6 tactical vehicles designed for use over
all types of roads, cross-country terrain, and in all weather conditions. The cab and
chassis for all vehicle models are similar. Each vehicle model is equipped with a unique
body and may be equipped with other auxiliary equipment depending on vehicle mission.
b. Capabilities.
(1) The vehicle operates in temperatures from -25°Fto120°F (-32°Cto49°C).
(2) The vehicle can ford water up to 30 in. (76 cm) deep for 15 minutes without damage
or requiring maintenance before operation can continue.
Change 1 1-17
TM 9-2320-366-10-1
1-10. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND
FEATURES (CONT)
(3) The normal operating range for the vehicle is 300 mi (483 km), based on 54 gal (204
L) of fuel and vehicle at maximum gross combination weight (wrecker at Maximum Gross
Vehicle Weight (MGVW)) when operated at an average speed of 25 mph (40 km/h).
Varying loads, prolonged idle, use of Power Take-Off (PTO), off-road driving, and climatic
conditions will affect operating range.
(4) Tiedown points are located so that the vehicle can be restrained in all directions
during air transport in C-130 and C-141 aircraft. The vehicles are capable of being
transported by highway, rail, and sea.
c. Features.
(1) An in-line, six-cylinder, 403 cid (6.6 L), turbocharged diesel engine, producing 290 hp
(216 kW).
(2) An automatic transmission with seven forward speeds and one reverse speed. The
transmission incorporates an integral transfer case. Normal mode is used when operating
the vehicle under usual conditions. Off-road mode is used when operating on unimproved
road surfaces. When operating in the normal mode, 70 percent of the power is distributed
to the rear axles and 30 percent to the front axle. When operating in the off-road mode,
power is evenly distributed between the front and rear axles.
(3) A power steering system consisting of a recirculating ball type steering gear box with
hydraulic boost. Mechanical linkage provides the Operator with control in the event of
steering oil pressure loss.
(4) A fuel system that includes; a 56 gal (212 L) capacity, 54 gal (204 L) usable fuel tank,
fuel/water separator with fuel priming pump, fuel transfer pump, secondary fuel filter, and
fuel injectors.
(5) Two front and two rear towing eyes with shackles.
(6) A manually operated pintle hook for towing a trailer or a disabled vehicle.
(7) A Central Tire Inflation System (CTIS) that allows the Operator to adjust tire pressure,
with the touch of a button, to suit terrain conditions.
(8) A cab with accommodations for three personnel, or two personnel if a radio is
installed.
(9) Service and emergency gladhands at the rear and front of the vehicle for towing a
trailer or disabled vehicle, or for being towed.
1-18 Change 1
TM 9-2320-366-10-1
(10) An air powered hydraulically operated system that allows the Operator to raise and
lower the cab and spare tire quickly and easily. This system also provides the Operator
with the means to safely and easily lower and raise the vehicle suspension for internal air
transport. In addition, a back-up hydraulic pump is provided in the event that there is not
enough air pressure available to operate the primary system.
