4.6.2.33 Post-test disassembly and examination Upon completion of
.
all endurance testing (see 4.6.2.29) complete the post test list in
accordance with column 3 of table III. Measure and record the
compression in each engine cylinder and dismantle the crane that
underwent endurance testing sufficiently to permit detailed
disassembly and visual examination of the following components:
a. Engine cylinder heads, all valves, two pistons
and piston pins
taken from the two cylinders having the lowest
compression.
b. Torque converter and transmission.
c. Universal joints and drive shafts.
d. Differential.
e. Front axle- bearings and seals.
f. Complete brake system components.
g. Steering system cylinders, valves, and pump.
h. Hydraulic system pump, valves, one cylinder of
each size,
control levers, and any hose and fitting where
leakage
occurred during and after the tests.
Additional disassembly and examination of this crane shall be made at
the option of the contracting officer. The crane shall be examined in
accordance with table II, column 1. Record complete description of
the condition of all parts and assemblies examined, and take pictures
of any deficiency. Each evidence of corrosion which affects the
functions of the crane or evidence of permanent deformation,
breakage, or excessive wear of any component shall constitute a
defect. Manufacturing tolerances listed in the contractor's quality
control program shall be made available upon request and shall be
used as the basis for determining excessive wear.
4.6.2.34 Nuclear-biological-chemical (NBC) protection. The crane
shall be tested in accordance with test method No. 27. Nonconformance
to 3.38 shall constitute failure of this test.
4.6.2.34.1 Electromagnetic pulse (EMP) The Government will
.
evaluate the schematics and electrical diagrams to determine possible
problem areas that may be encountered on the end item. A
preproduction crane shall be subjected to non destructive EMP testing
-
by the Government at a Government facility.
4.6.2.35 DCA capability. The contractor shall perform a 100 percent
visual inspection of all DCA wiring harnesses prior to installation
on the crane to insure wires and connections are free of error. After
installation on the crane, test the DCA harness (reference chapter 5
of design guide for DCA) on each vehicle with the DCA tester (GFE))
prior to interfacing with STE/ICE as required under 4.6.2.35.1.
Nonconformance to 3.41 shall constitute failure of the DCA.
