Some Soldiers think it’s a good idea to use high-pressure water or a steam cleaner to
make the inside of a gun tube sparkle. Others buy special cleaning machines over the
Internet. One unit even tied the cleaning staff to a forklift and went full speed ahead!
Every one of these ideas will cause damage that’ll shorten the life of a gun tube.
Water corrodes gun tubes while also damaging breech mechanisms, bore evacuator
components, and Fring circuits. Untested machines can chip and scar the inside of a
gun tube. And what’s up with that forklift?!
T
he 11 bolts, NSN 5305-01-014-5124, on top of your tank’s turret are there for a
reason, crewmen. And it’s not for mounting flag brackets, roadwheels, lights or other
items!
Those bolts protect the threads inside each of the holes where the turret lifting
device is attached. Mess up the threads and there’s no safe way to separate the turret
from the hull for sustainment-level repairs.

If you’ve removed any of the bolts or some come up missing, check the holes to
make sure they’re clean and free of debris. Then, add a little antiseize compound,
NSN 8030-00-597-5367, to the threads before torquing the bolts to 50-75 lb-ft. The
antiseize compound prevents corrosion and reduces wear and tear on the threads.
