equipped with devices which compensate for differential torque and speeds between front and
rear axles, the transfer case shall provide for driver selection of either two-wheel or four-wheel
drive. When furnished, interaxle compensating devices shall provide for positive transfer of
power to all driving axles. When a two-speed transfer case is furnished the speedometer shall
read accurate speed with the speed selector in high or low range.
*
3.4.5.2 Clutch. The clutch shall be the largest capacity clutch offered for the type and
class vehicle and engine furnished with torque capacity exceeding the maximum delivered
engine torque. The clutch lining shall be asbestos free.
*
3.4.5.3 Automatic transmission. When specified (see 6.2), the vehicle shall be provided
with an automatic 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 a power takeoff opening. The input torque capacity of the transmission shall be at least
equal to the maximum torque delivered by the engine.
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, in proportion to the number of driving axles furnished.
3.4.7 Frame. The chassis frame shall be the manufacturer's standard for the vehicle
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 the 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.
*
3.4.9 Ax1e. Axle ratings shall be at least equal to the load imposed on each measured at
the ground, with the vehicle loaded to specified GVW. When specified (see 6.2), the wheel
bearings and axle spindles shall be oil lubricated. The hubcaps, except for driving axles, shall
have a window for visual determination of oil level. Provisions for venting or withstanding
internal pressure buildup and for replenishing the oil supply shall be provided.
