3-KW Generators…
Simply screw in a drain pipe extension,
NSN 2805-01-045-9735, into the engine oil
drain opening. A magnetic oil drain plug,
NSN 4730-00-788-0441, then screws into
the end of the extension. This extension
clears the generator and allows oil to be
drained directly into a drain pan.
We still recommend how PS solved in the
problem in PS 373, Dec 83.

raining the oil from a 3-KW gen-
erator can be a big mess. Before the
oil reaches a drain pan, it hits the
generator frame, then splashes and
spreads.
Many homemade fixes have made
their appearance over the years,
including drip pans of all shapes
and sizes, funnels and hoses.

ater is entering 3-KW TQGs, NSN 6115-01-285-3012 (60 HZ) and NSN 6115-
01-287-2431 (400 HZ), and collecting in the A8 frequency converter. Soon the
converter shorts out and your unit is shelling out three grand to replace the 400 HZ
converter, NSN 5895-01-477-0858, or four grand to replace the 60 HZ converter,
CECOM says the water problem is coming from high-pressure washing of the
generator. The generators are made to shed rain, but pressurized wash water can
force its way in and do a great deal of damage. Seems
like the A8 frequency converters are suffering the most.
So nix the high-
pressure power
washing of your 3-KW
TQGs unless you feel
a few thousand bucks
is a fair price to pay
for a cleaning.
