hecking the alignment of the serpentine belt used on M998A2-series and
M1113 and M1114 trucks is a whole lot easier if you have a tool specially
designed for the task.
With the tool, you can tell if the belt pulleys and brackets are aligned right. If
they’re not, the belt gets chewed up and thrown off.
Plans for the homemade tool are found in TB 43-0001-62-2 (Jul 99) on Pages
9-22 through 9-24. Info on
how to use the tool and
make any necessary
adjustments is also
found in the TB,
starting on Page 9-25.
All this info is also in Change 2 (Jun 99) to TM 9-2320-280-20-2.
If you don’t have the change or the TB, contact your local TACOM logistics
assistance representative. Still no go? Send Half-Mast your mailing address and
he’ll get you the info.
aise the hood on any 10 HMMWVs
and you’ll find bent radiator and oil cooler
fins on at least 7 of them. Why? Because
the fins get bent by feet, tools and other
heavy stuff during PMCS and repair work.
OK, so the fins get bent. So what? So,
when enough of them are bent, the flow
of air through the cooler and radiator is
restricted. That leads to engine and trans-
mission overheating.
What can be done about it? Plenty. Make
and use a fin protector for all those times
you’ve got to get up close and personal
with the engine area. Here’s how:
Cut a piece of

The measurements are approxi-
mate, so you may need to adjust
them a little for your HMMWV.
Round off the edges and paint the
board to avoid splinters.
To use the board, remove both
HMMWV eye-hook seals and slip
it over the two lifting rings. Lay it
flat on the oil cooler frame.
After you’ve finished your PMCS
or repair work, remove the protec-
tor, replace the eye hook seals and
check the cooler and radiator for
bent fins. Line ’em up with the fin
straightening tool, NSN 5120-00-
157-2180, in the Common shop sets.

may be
