A
lot of hydraulic pump assemblies, NSN 4320-01-579-1044, on the M978A4
HEMTT have failed. That’s not good news because the hydraulic pump assembly
is a vital and expensive component of tanker fueling operations. If it fails, fueling
operations come to a screeching halt!
But here’s some good news. Units can get a new and improved hydraulic
pump assembly, NSN 4320-01-618-6603, at no cost through the Oshkosh warranty
claim process.
Warranty Walk-thru
In a nutshell, your unit will notify Oshkosh of the failed part, then Oshkosh will
conFrm it. Units are responsible for installing the replacement hydraulic pump
assembly they get from the manufacturer.
Make sure TM 9-2320-326-14&P in IETM EM 0288 (Oct 08) is used to verify
your M978A4 HEMTT’s hydraulic pump assembly has failed. Your unit can request
the replacement pump by emailing a warranty claim form to Oshkosh Corporation at:
warrantyclaims@defense.oshkoshcorp.com
Download a copy of the claim form at:
?t=soum&f=OshkoshWarrantyClaimFrm.xlsx
±or accountability and tracking purposes, you must also send the warranty claim
to TACOM LCMC’s HEMTT equipment specialist, Jaime Albers, at:
jaime.t.albers.civ@mail.mil
Warranty Window
The improved hydraulic pump assembly has a 12-month warranty that starts the
day the pump is shipped to the warranty location.
And the old hydraulic pump assembly now has an extended warranty. The
warranty for Active Duty units ends on 1 Sep 15. Because their fuel tankers aren’t
used as much, the warranty for National Guard and Reserve Components doesn’t
end until 1 Sep 17. Once the warranty expires, units will have to pick up the tab for
replacements.
Upcoming Update
The new and improved hydraulic pump assembly will be included in the next
TM update.

Dear Half-Mast,
We have trouble
with water coming
in the M1151A1
HMMWV’s gunner
turret. Water
can short out the
expensive electronics
inside the HMMWV. Is
there a tarp we can
order that will keep
out the water?
Mr. D.M.
Dear Mr. D.M.,
There is no tarp in the Army
system made specifcally For
the M1151. However, NSN
a 12x7-Ft tarp that can be
strapped in place with some
bungee cords. Or iF your post
has a canvas shop, get them to
make you a cover.
