Dear Editor,
We’ve received reports from the field that HMMWV radiator mount
bracket welds are breaking. This is most likely due to excessive vibration
and jarring when Soldiers drive over uneven and rough terrain.
The current operator PMCS criteria for radiator damage in TM 9-2320-
280-10 doesn’t allow for
any
broken radiator mount bracket welds. So if
just a single bracket weld breaks, the HMMWV is not fully mission capable
(NMC). Now TACOM LCMC is changing that.
Until the -10 TM is updated, please have your readers go to Item 53c
in PMCS Table 2-2 of TM 9-2320-280-10 (Jan 96, w/Ch 3, Jul
04). Have them pencil in the following change in the
Not Fully Mission
Capable If
column:
“Support mounts broken, damaged, or missing
hardware. Side brackets damaged or two or more weldments
broken allowing movement of radiator”.
M
echanics, do enough maintenance on MRAPs and eventually you’re going to need
a jack and some jack stands, especially if you’re stationed in Afghanistan.
But there’s a slight problem. There hasn’t been an authorized jack or stand available
that’s rugged enough and with enough lifting capacity to do the job.
Problem solved! TACOM has put together just what you need: a 20-ton hydraulic
jack, NSN 4910-01-583-5138, and a pair of 10-ton high boy jack stands, NSN 4910-
01-583-5140.
Check out maintenance information message (MIM) 10-049 for more information.
You’ll fnd the MIM at the AEPS website:
The jack and jack stands can be requisitioned
as part of the additional authorized list for the
SATS (Standard Automotive Tool Set) in support
oF feld maintenance oF MRAP vehicles.
By the way, TM 9-2320-387-10, the operator’s manual for up-armored
HMMWVs, has already been updated with this info.
