M12A1 Decon…
Dear Editor,
Here at the Chemical School, we M12A1 decon instructors give our stu-
dents these three tips for better deconning:
Idling
-
The M12 TM says
to idle down the decon for at
least 15 minutes at shutdown
so it can cool down. But it
doesn't say at what rpm.
We've found 1,500 to
2,000 rpm is the best idling
range. If it's lower, the engine
will stall.
Lubing
-
When you're doing
your quarterly lubing accord-
ing to LO 3-4230-209-10,
make extra sure to hit Valve
#1 with GAA. We've found
the valve breaks if it doesn't
get regular lubing. Anytime #1
turns hard, give it a shot of
GAA. In fact, do that with
any of the four valves.
Diesel
-
If you have an M12
with the new diesel engine,
remember it has different
idling and operating rpm
requirements than the gas
engine. See TM 3-4230-
237-10, the TM for the
diesel M12, for details.

You're sure not conning us
with those excellent decon suggestions,
Sergeant. Thanks for sharing.)
