 BEWARE THE SHORT RAM
s ?7....,L !,,, ,,


 .
 Here're some of the defects and bad operation practices that'll cause a short
ram-meaning the chain won't extend far enough to seat the projectile in the
175-mm or 8-incher's tube:


1. Easing the valve handle or
 creeping or feathering. You
 want that rammer control
 valve wide open (full ram)
 throughout the entire ram,
 man


2. A bent or misalined loader
 tray or trough that causes
 the rammer chain to get
 hung up.


 3. An improperly adjusted
 trough latch which causes
 the trough microswitch (tray
 interlock switch) to lose con-
 tact. This'll result in flutter-
 ing in the chain-a short
 ram due to intermittent loss
 of power.

4. An improperly adjusted
 loader-rammer pivot stop
 which also causes the micro-
 switch to lose contact and a
 fluttering in the chain.


5. A rammer check valve or flow regulator metering
 valve that's put in backwards could also give you a
 bum ram. So, if the chain extends fast and comes back
 slow or if the chain extends one distance one time

6. A bent or sprung rammer rack roller
 that'll let the rammer rack climb
 over the teeth of the rammer gear.
 This'll result in loss of power and a
 short round. And it'll mean you'll
 have to retime the rammer chain.


7. A buildup of stringy residue C N LHF AFER
