|  MIL-V-62358(AT)
an alternate to MIL-L-2104 for transmission acceptance testing, production surveillance, and
break-in operation. Oil conforming to MIL-L-2104, Grade 10, or MIL-L-21260, which conforms
to MIL-L-2104, Grade 10, with 135 to 270 ppm biocide shall be used for solenoid valve assembly
bench testing unless otherwise specified (see 6.2).
4.3.1.3.1 Filtration. Supply oil shall be filtered to requirements of Drawing 12267989.
4.3.1.3.2 Supply pressure. Supply oil pressure shall be 180-370 psi in the transmission
installation with pressures as specified in 3.5.2, 3.5.3, 3.5.4, 3.5.5 and 3.5.6.1 in solenoid valve
assembly bench testing.
4.3.1.3.3 Supply temperature. Supply oil temperature shall be 175 to 2650F in the
transmission installation with temperatures as specified in 3.5.2, 3.5.3, 3.5.4, 3.5.5 and 3.5.6.1 in
solenoid valve assembly bench testing.
4.3.1.3.4 Supply flow capacity. Supply oil flow capacity shall be 2.0 0.1 gallons per
minute.
4.3.1.4 Test equipment. Assembly test stand shall be used in the performance of the
inspection and tests specified herein. Test stand shall include provisions for mounting solenoid
valve assembly using installed interface configuration for its intended application (i.e. hard
mounted on a one to two inch thick steel plate or equivalent). Provisions shall be made for
supplying heated, filtered oil (up to 2 GPM) to solenoid valve inlet through a 0.037 + 0.001 inch
diameter by 0.25 + 0.02 inch long feed orifice. In addition, provisions shall be made to apply
electrical power across the solenoid lead wire and mounting face (positive to lead wire). Test
stand shall incorporate meters and gages necessary to measure and record the following
parameters during solenoid valve assembly test:
(a)
Oil supply pressure - psi
0-200 psi + 2 percent
(b)
Oil cavity pressure - psi
0-200 psi + 2 percent
(between feed orifice and
solenoid valve)
Oil temperature - 0F
500 -2750F
(c)
+ 2 percent
(d)
Applied voltage - volts dc
0-40 vdc + 2 percent
(e)
Solenoid coil resistance - ohms
0-100 ohms + 2 percent
4.4 Preproduction and initial production.
4.4.1 Preproduction inspection. Twenty preproduction samples (see 3.1) shall be inspected,
at a location approved by the Government, to determine conformance to requirements of this
specification. Inspection shall consist of examination as specified in 4.5.2 and all tests specified in
table II.
4.4.1.1 Preproduction inspection failure. Failure to pass any examination or test shall be
cause for refusal to grant preproduction approval until corrective action taken by the contractor
has been approved by the Government.
