MIL-C-62310A(AT)

4.7.4.1 Engine air induction systems examination. To determine conformance to 3.4.4.1, the

engine air induction system shall be examined for proper installation and absence of leaks.

4.7.5 Exhaust systems toxic fumes test. To determine conformance to 3.4.5, the exhaust

systems shall be examined for proper installation and absence of leaks. Toxic fume levels,

measured in the driver and crew compartments, shall not exceed specified values. For the test,

the vehicle shall be sealed, the engine operated at 900 to 1,000 rpm and the personnel heater, if

installed, operated at high heat, for a period of not less than 30 minutes. However under ambient

or test temperatures that exceed 55F, the automatic shut-down of the heater before 30 minutes is

acceptable.

4.7.6 Fuel system grades and slopes test. With the vehicle operating on specified grades and

slopes, the vehicle engine and fuel system shall be observed to determine conformance to 3.4.6.

4.7.6.1 Fuel cell test. To determine conformance to 3.4.6.1, the fuel cell shall be examined

for cleanliness. The fuel cell(s) filled to capacity, and all fuel lines and connections, shall be

examined for leakage before and after the testing specified in 4.6.4.

4.7.6.2 Fuel and hydraulic systems leakage examination. To determine conformance to

3.4.6.2, the fuel and hydraulic systems shall be examined for leaks at all connections and sealed

items before and after a road test on smooth, level, hard-surfaced road. Verify for internal

cleanliness of the fuel cell and hydraulic lines prior to initial fueling and servicing of vehicle.

4.7.6.3 Rack linkage examination. To determine conformance to 3.4.6.3, the accelerator

pedal shall be operated to full throttle, and the rack examined to assure that full open position has

been reached when pedal is in contact with stop.

4.7.7 Transmission, transfer gear case and controlled differential test. To determine

conformance to 3.4.7, transmission, transfer gear case and controlled differential shall be

examined for proper assembly and operated throughout all gear ranges, and examined for proper

installation and absence of leaks. Prior to assembly and installation, all lubricant and hydraulic

lines shall be examined for internal cleanliness.

4.7.8 Ammunition racks test (M106A2 and M125A2). To determine conformance to 3.4.8,

ammunition racks and fastening devices shall be examined for proper installation and positive

fastening, and observed during vehicle operation for proper retention and support of ammunition.

4.7.9 Electrical systems test.

4.7.9.1 Generating system voltage (alternator) test. To determine conformance to 3.4.9.1,

with the alternator operating as specified, a voltage measurement shall be made with a voltmeter

after described load is removed, and immediately after the road test.
