b. FEEDER DRIVE ASSEMBLY: Mounts and drives the forward feeder section components and controls feed selection. Provides a means to manually operate the gun during a power failure, and sends electrical signals to the turret controls indicating the position of the bolt. The feeder drive assembly contains the following components:

(1) WORMSHAFT ASSEMBLY: Driven by the auto gun receiver drive shaft. The wormshaft assembly turns the worm wheel gear and also provides a means to manually operate the gun through the manual drive gear.

(2) WORM WHEEL GEAR: Drives the gear clutch assembly.

(3) GEAR CLUTCH ASSEMBLY: The spur gearshaft, of the gear clutch assembly, drives the upper spur gear and the index drive shaft with the clutch spur gear. The gear clutch assembly also provides for timing the index drive section with the feed shaft section. The clutch will slip if the automatic gun feeder jams.

(4) UPPER SPUR GEAR: Drives the lower spur gear and the upper sliding sleeve clutch (when engaged by the electrical solenoid).

(5) LOWER SPUR GEAR: Drives the lower sliding sleeve clutch (when engaged by the electrical solenoid).
