Don’t use cover screws
to draw cover tight
epairing a flat or replacing a tire is
the perfect time to inspect split-ring
wheels on tactical trucks.
Here’s what to look for:
Split and Lock Rings
ike everything else, mechanics,
there’s a right way to install the trans-
mission oil filter elements on your
FMTV. That’s right, element
s
. Plural.
There are
two
oil filter elements that
must be changed at each service. One
of the elements is easy to get to, but
you’ve got to remove the propeller
shaft to reach the other.
Tactical Trucks . . .
Cracks in base? They’re caused by
tools during assembly or disassembly,
overloading or overinflating tire.
Replace rim.
Rust? Use
wire brush
to remove
it. Then
paint rim. If
you paint
with CARC,
refer to
TB 43-
0242. If you
paint with
anything
besides
CARC,
see TM
43-0139.
Wheel Rim
Cracks? Any crack in lock ring
means it will break. Don’t use it!
Cracks in
disc? They’re
caused by
loose lug nuts
or overloading.
If you find any
damage to rim,
replace it.
Erosion? Corrosion causes bead
seat of lock ring to erode and chip.
Then ring won’t seat properly, so
replace it.
Sprung or out-of-round? Ring
won’t seat properly into rim. If you
find a bum split ring, replace it.
Then note this:
Do not use the
cover screws to
draw the cover
and element to
the sump.
That can
break covers,
crush elements
and pinch seals.
Instead, push
the cover and
element into the
sump and install
the six screws finger tight. Then torque
the screws in a criss-cross pattern to
38–45 lb-ft.
Don’t think you can short-cut the
service by skipping the hard-to-get-to
element. That won’t work. All you’re
doing is risking transmission failure.
Just as importantly, when you install
each element pay attention to the in-
structions in your truck’s -20-3 TM.
