HEMTT…
leaky filter gets wired
Dear Editor,
The engine oil filters on our HEMTTs leak. A little investigation on
our part turned up the reason.
The oil filter housing on each HEMTT is made of aluminum, but the
plug in the bottom of the housing is steel. Since aluminum heats up
faster than steel, the housing expands faster. Add some vibration and
the result is a loose plug and an oil leak.
If
enough
oil
leaks,
your
HEMTT could end up with severe
engine damage.
We prevent this problem by
drilling a tiny hole through the
plug and safety-wiring it to the
metal bracket that holds the
strap for the transmission cool-
er lines. The safety wire keeps
the plug from turning and stops
the leaks.

am I going to
do about this

oth plastic and aluminum taillight assemblies can be found on tactical vehicles.
Plastic assemblies outnumber metal ones, and eventually the metal assemblies will
be gone.
But until then, be aware that
the lenses for the different
assemblies are not interchange-
able. That is, don’t try to use a
lens meant for a plastic assembly
on a metal assembly, and vice
versa.
The lenses will not fit correct-
ly if they’re mixed. You’ll get lots
of moisture in the lights—which
leads to corrosion and lights out!
hey baybee!
My
sign is
aluminum!
So is
mine!

I’m sorry,
lennie. But
we’re just
not
made
for each
other.
But,
