Oh, Those Unlucky Leaks!
E
ver gone on a long trip and run out of gas on the way? It’s even worse if you Fnd out
that a fuel leak was the cause.
That’s why it’s important to take a good look at the fuel transfer lines on your Stryker,
especially before a long training mission or operation.
Just open the access
plate at the rear of the
vehicle and check the
lines for fuel leaks. If
you see any, report ‘em!
After all, who wants a
highly flammable liquid
sloshing around under
their feet?
Before you reinstall
the access plate, take a
minute to clean away
any dirt or sand that’s
built up on the recessed
lip of the floor plate.
That crud can keep
the access plate from
fastening properly. It’ll
go flying the next time
you hit a big bump!
T
rying to estimate the remaining life on your M777A2 towed howitzer’s M777 or
M776 cannon tube? A recent addition to TM 9-1000-202-14,
Evaluation of Cannon
Tubes
(Feb 99), can help.
Change 4 (Dec 08) to the TM added serviceability and condemnation criteria for
the cannon tubes. The new info is listed in Appendix S. If you don’t have the latest
copy of the TM, download it from the LOGSA ETM website:
You cannot estimate the equivalent full charge (EFC) count for these cannon tubes
by doing a pullover measurement. Nor can you estimate the remaining life by using
the wear table for the M198 howitzer. The safe service fatigue life of the howitzer’s
M776 cannon tube is drastically different than the M198’s cannon tube.
In fact, you should
never
enter a remaining EFC life value on the DA Form 2408-4
gun card that is anything other than
actual
on the M776 cannon.
If you suspect you have an inaccurate EFC count or have lost the gun card, call the
Army Benet labs at Watervliet Arsenal, DSN 374-5823/5586 or (518) 266-5823/5586
for help. You can also get help from one of the gun card POCs listed on
