ver wish your problems could just disappear? Well, one problem with HEMTT A4
trucks that rolled off the line between Mar 10 and 3 Aug 12 and all PLS A1 trucks
produced before 3 Aug 12 is about to do just that. Vanish!
A production issue caused a cab wiring harness to rub against a grease Ftting on the
steering column of these HEMTT A4 and PLS A1 trucks. That contact can lead to a
damaged wiring harness, including sparking of exposed wires or shearing of the wires.
But the good news is, steering and other safety-related functions aren’t affected.
More good news is that Oshkosh Corporation will inspect and modify suspect trucks.
In fact, Oshkosh will provide the required parts and labor to correct this problem
at no cost to units. The repair work will include removing and disposing of the
problem grease Ftting, installing a plug to Fll the opening, and adding two half-inch
wide cable ties.
The trucks that need to be Fxed are identiFed at this link:
?t=mam&f=HEMTTA4PLSA1STEERWI.xlsx
Units should schedule repairs by contacting Christopher Schweitzer at:
cschweitzer@defense.oshkoshcorp.com
And you shouldn’t see this problem in the future because the steering shaft wiring
harness change was added to HEMTT A4 and PLS A1 production on 3 Aug 12.
What about the TMs? The HEMTT A4’s TM 9-2320-326-14&P (EM 0288, May 09),
and the PLS A1’s TM 9-2320-319-13&P (EM 0298, May 09) will be updated in the
next revision. The grease Ftting will be removed and two half-inch wide cable ties will
be added.

in
another, all tires don’t come as
a standard size either. Ordering
±MTV wheel assembly, NSN
can
bring
two different tires. So make
sure you take a good look at the
manufacturer and the tread. The
Goodyear tire is about an inch
taller than the Michelin option.
±inally, make sure your spare tire matches the tires on your truck. The spare needs
to at least match one of the axles. As a general rule for all Army vehicles, make sure
the spare tire matches the tires that are already installed.
M1117 ASV Seat Switch NSN
If the electric switch for the hydraulic seat on your M1117 armored security vehicle
(ASV) goes bad, don’t replace it with NSN 6150-01-577-4987 (Item 1 in Fig 69A of TM
9-2320-307-24P). That brings the switch and bracket at a cost of almost $1,650! Instead,
reuse the old bracket and replace just the switch with NSN 5930-00-765-5719. That sets
you back only $51.88.

if you do, you’ll

mixing raises
safety concerns…
but if the tires on

you’re
gOod!
I’m going
