4.5.1.22.4 Control system deadspot check. To determine conformance to 3.6.14.2.4, with
the cab and gun controls operated as specified, the control system deadspot shall not exceed that
specified.
4.5.1.22.5 Hydraulic control system leakage check. To determine conformance to
3.6.14.2.5, with the system fully charged, the pressure drop shall be not less than that specified.
4.5.1.22.6 Hydraulic accumulator test. To determine conformance to 3.6.14.2.7, the
elevation and traverse power switch "off" and the cab lock engaged, all oil shall be discharged
from the main accumulator by actuating the cab power shut off solenoid button and moving the
power traverse handle to extreme right or left until the system pressure gage is stabilized at a zero
pressure setting. Leakage from initial precharge condition shall be not more than 2 percent in
24 hours and one psi per degree temperature change. With the specified nitrogen pressure on the
gas gage, the controls in neutral position, and the oil pressure at zero the test shall be continued
by observing the oil gage for a period of 3 minutes with no gage movement.
4.5.2 Control test. Control tests for maintaining control of those requirements whose
inspection would be or too long duration to be included under acceptance tests shall be conducted

Government inspector shall stop acceptance of subsequent lots until evidence has been provided
by the contractor that corrective action has been taken.
4.5.2.3 Contamination test. To determine conformance to 3.4.1, 3.4.1.1, 3.4.1.2, the vehicle
after the water fording and flotation test shall be examined for contamination of lubricants of the
transmission, engine, final drives, and road wheels 2, 3, 4, 5, and one of their corresponding area,
on each side of the vehicle. Contamination shall not exceed 2 percent.
4.5.2.4 Fuel system slope test. To determine conformance to 3.4.8, with vehicle headed up
and down a 60 percent longitudinal slope, and each side up to 40 percent slope vehicle shall be
checked for functional requirements.
4.5.2.5 Fuel tank and lines test. To determine conformance to 3.4.8.1 and 3.4.8.2, the fuel
tanks shall be filled to capacity at a rate of not less than 50 gallons per minute. The tanks and
lines shall be checked for leaks before and after a two mile road test on smooth, level,
hard-surfaced roads.
