CHAPTER 7
DIRECT SUPPORT MAINTENANCE OF RAMMER SYSTEM
GENERAL
This chapter illustrates and describes maintenance of the weapon mounted projectile rammer system. The rammer as-
sembly is a hydraulically powered device which is controlled by a hand operated actuating valve assembly. No electrical
circuits are used in the system. A second valve in the system, the blocking check valve, prevents rammer assembly from
being operated unless it is correctly alined with the chamber.
