echanics, the Axis A oil nozzle on the UH-60 and the AH-64 engines requires
special attention.
Keep an eye on the Axis A oil nozzle when hand cranking the engine to identify
symptoms and corrective actions during troubleshooting or when replacing the
engine starter.
Use extreme caution when removing and installing the Axis A cover assembly
to avoid contact and damage to the Axis A oil nozzle. Remove the engine coupling
retaining bolt and hold the radial drive shaft assembly using a ratchet with a
1
/
4
-in
drive adapter and a
5
/
16
-in socket to prevent turning when removing the bolt.
As you place the
1
/
4
-in drive adapter on the radial drive shaft to keep it from
turning, make sure that it does not hit the oil nozzle or rest against it. The removal,
replacement and installation instructions are in WP 0695 of TM 1-1520-237-23.
The nozzle has a very tiny hole to spray oil through. The slightest damage to the
oil nozzle means it won’t be able to provide oil to the radial drive shaft and the Axis
A bearing in the gearbox.
Then the engine oil pressure drops, starving the radial drive shaft and the bearing
assembly of oil. You could end up replacing a burned-out gearbox caused by a lack
of oil.
Steer clear of the Axis A
oil nozzle when replacing the
engine starter and you’ll avoid
major engine repair. Also, to
prevent oil loss and possible
in-fight shutdown, make sure
the Axis A cover assembly is
reinstalled correctly. Check out
the instructions in WP 0398 of
TM 1-2840-248-23&P.
Dear Editor,
I take in SINCGARS systems
for theater-provided equipment
(TPE) Reset and reintegration.
Commanders need to know that
when they turn in SINCGARS TPE,
that equipment is no longer theirs.
It will be reissued to other units.
PBOs must drop that equipment
off their unit’s property books.
Make sure the correct serial
numbers are used.
Commanders also need to
understand that their unit’s
organic equipment-not theater
provided–should not be turned in
to TPE RESET.
Finally, we are finding SINCGARS
equipment with the wrong data plates.
We have found wrong data plates on
all models, but it is especially a problem
with the older, wide-body models.
If you think you have a SINCGARS
piece of equipment with the wrong serial
number or labeled incorrectly, contact
your CECOM IT Radio LAR. The LAR
will help you identify your system and
make sure you’re following the correct
Reset procedures.

Editor’s note:
Equipment from overseas is streaming back. All of it will need
to be Reset and much of it will be reissued or stored. Keeping good accountability
will be hard, but it’s a must. It is also everyone’s responsibility. We cannot afford
a “pass it off and forget about it” mentality. Don’t make it the next Soldier’s
problem. Commanders and top NCOs, make sure all your property is accounted
for and that it is listed under the right serial numbers.
