3.4.5.1 Clutch. The clutch shall be the largest capacity clutch offered for the vehicle and
engine furnished with the clutch torque capacity exceeding the maximum delivered engine
torque.
*  3.4.5.2 Automatic or semiautomatic transmission. When specified (see 6.2), the vehicle
shall be provided with an automatic or semiautomatic transmission. The transmission shall
include a hydraulic torque converter and not less than four forward gear ratios. Normal driving
range selector position shall provide not less than four gear ratios without movement of the
selector. The transmission shall be provided with SAE J704 power takeoff openings. The input
torque capacity of the transmission shall be at least equal to the maximum torque delivered by
the engine.
3.4.5.3 Power takeoff. A power takeoff shall be furnished. The power takeoff shall be of a
rated capacity to operate powered equipment. Controls to operate the power takeoff shall be
located in the truck cab accessible to the seated driver. A caution plate or decal reading "DO
NOT OPERATE VEHICLE AT HIGHWAY SPEEDS WITH POWER TAKEOFF ENGAGED"
shall be installed so as to be readily visible to the seated driver.
3.4.6 Driveline components. Driveline components shall be adequate to transmit the
maximum delivered torque of the engine, as developed through the maximum gear train
reduction. The driveline shaft for front mounted winches, when specified in procurement
documents, shall have an angle not greater than 16 degrees from the longitudinal plane.
3.4.7 Frame. The chassis frame shall be the manufacturer's standard for the vehicle
furnished. The vehicle shall have a frame with reinforcement extending at least from the rear of
the front suspension, rear hanger bracket to the front of the rear spring, front hanger bracket.
Reinforcement shall provide sufficient structural strength in the chassis frame through increased
resisting bending moment to at least equal the load imposed, with the dump body loaded to
provide specified GVW. A heavy duty frame with a resisting bending moment of not less than
600,000 inch-pounds may be furnished. Chassis frame rails shall not project beyond the rear end
of the body.
3.4.8 Suspension. The vehicle shall be equipped with a suspension system with components
having a rated capacity at least equal to the load imposed on each member, measured at the
ground, with the vehicle loaded to specified GVW. When suspension capacity is rated at the
spring pads, unsprung weight shall be deducted. The vehicle shall be equipped with hydraulic,
double-acting shock absorbers at the front wheels.
