d. Visually examine to assure that the spring pin that
retains the feeder gear to the feeder shaft is flush or
below the surface of the feeder gear (see Dwg.
11701120).
4.4.2.2.9 Push rod assemblies and push rod rollers.
Manually rotate the feed gear and feeder shaft to assure-proper
function of the push rod assemblies (see 3.4.9).
4.4.2.2.10 Round direction plate. Visually and manually
examine the round direction plate to determine compliance with
3.4.10.
4.4.2.2.11 Marking. All markings required by applicable
drawings shall be visually examined for clarity and legibility
(see 3.5). Visually and manually examine the identification
plate to determine compliance with 3.4.8 and to assure that all
pertinent data has been applied.
4.4.2.2.12 Lubrication. Visually examine the feeder to
assure that all functioning surfaces have been lubricated (see
3.4.12).
4.4.2.2.13 Timing. Feeders shall be examined for the
timing requirement (see 3.4.13) using the inspection equipment
conforming to Drawing 11702138. The feeder shall be assembled to
the timing gage and the feeder sprocket shall be rotated until
the timing pin can be engaged in one of the feeder gear timing
holes. The gear alignment pin of the gage shall then be
depressed between the nearest feeder gear teeth as the timing pin
is released. With the feeder sprocket in this position for each
of the seven timing positions, the gage shall indicate whether
the timing requirement has been met.
4.4.2.2.14 Torque. The torque required to manually start
rotation of the feeder shaft without ammunition (see 3.4.14)
shall be measured and recorded. The recorded measured values
shall be forwarded in accordance with 6.3.
4.4.3 Testing.
4.4.3.1 Solenoid dielectric withstanding voltage, solenoid
operation, and functioning testing. The contractor shall test
each feeder for solenoid dielectric withstanding voltage
solenoid operation and functioning using the test method
specified in 4.5.1, 4.5.2, and 4.5.3 respectively. Feeders
failing to meet the requirements shall be rejected.
