If the hose does not show wear, and is not routed beneath the distribution manifold,
but still is not in the proper location above the manifold, just leave it alone for now.
The contractor will re-route the hose to the correct position during installation of the
production Fx to HEMTT -A4s mentioned in TACOM SOUM 10-003.
Also, you may need extra slack to re-route an existing hose. Loosen the
hose clamps and pull enough of the hose through to get the slack
needed to route the hose above the distribution manifold.
The drain hose can be zip-tied to the supply hose
for the radiator hydraulic motor fan. This supply
hose is line 2976 in the hydraulic schematic
and comes out of a T-Ftting at the front of
the distribution manifold.
If
wear
causes
you to
order
a
replacement hose, use PMCS guidance
to inspect your -A4 HEMTT hose
daily for leaks while waiting for
the part to arrive. Deadline the
truck if you Fnd class III leaks
in the hydraulic drain hose.
Dear Editor,
I’m a contractor in Kuwait, and we found an issue with the power takeoff
(PTO) control assemblies for M939-series trucks.
TM 9-2320-272-24P-2 gives the same NSN for Item 13 of Fig 525
and Item 16 of Fig 528. The problem is that these are actually two
different items.
We later learned the correct NSNs: Item 13 of Fig 525 is NSN 2590-
01-083-1155 (PN 11669342-1) and Item 16 of Fig 528 is NSN 2590-
01-106-2060 (PN 11669463).
Would you do me a favor and tell your readers about this correction?
That will help out units and other contractors who run into this problem.

if the hose shows
signs of wear,
replace

if the hose is routed beneath the manifold,
regardless of whether or not it shows wear,
re-route the hose to go
