if you have a base
expeditionary targeting and
surveillance system-combined
(BETSS-C),
listen carefully.
The BETSS-C
is powered by
one of these
generators…
Here’s where to
look in the TMs
for PMCS work
packages…
And here’s a
closer
look
at some
common
maintenance
problems
and their
solutions…
ENGINE OIL:
When the engine is low on oil, parts can seize and the engine can
fail. Low oil pressure can cause cylinders to dry out and throw rods. Too much oil
creates pressure that can blow O-rings and the gasket to the valve cover. And that can
break the seals in the engine block.
Here’s how to make sure the engine has the right amount of oil:

Shut down the generator set before checking the oil level or adding oil.
That’s exactly what’s happening. Recently, some
TQGs powering the BETSS-C stopped running
because Soldiers neglected preventive maintenance
checks and services (PMCS). In some cases, the
failed generator or its parts were beyond repair.
If the TQG goes down, the BETSS-C has no electrical power. Security monitoring
and surveillance suffer. You’ve lost your eyes and ears.
