Dear Editor,
Keeping track of the hours of operation on the 5-kW auxiliary power unit
(APU) is an important part of PMCS on the M1068A3 command post carrier.
Logging the number of hours the engine has run between services is critical.
Logging the hours is how you know if the APU is due for an oil change or
if the fuel injector needs to be replaced, for example. It’s also how you know
when to check the fuel filter, inspect the oil cooler and adjust the engine
valve clearance.
But
many
times,
logging
those hours gets overlooked
simply because drivers don’t
know where the hour meter is
located. The opening in the
APU’s casing isn’t marked, so
it’s easy to miss.
An easy solution is to stencil
“Hour Meter” above or below
the hour meter opening on the
APU. That way crews can easily
find the hour meter and keep
track of those hours.

Editors note:
That’s a great suggestion, Sergeant.
Crewmen, be sure to follow the PM procedures in
TM 9-6115-644-13&P to keep those APUs working.
