So mechanics, before you use
the exposed part of the forward
and aft skid cross tube as a step to
install pillows and covers, apply
some
non-slip
material,
NSN
8010-00-641-0427, to the cross
tubes.
Otherwise,
when
the
tube
gets wet or oily it becomes very
slippery. Some mechanics have
slipped off the tube and smacked
their head against the upper door
frame. That hurts!
To avoid bumping your head against the airframe, make sure the tube has non-slip
material applied before you step on it.
E
ven though you’re Army strong, don’t underestimate the weight of the AH-64 generator.
When it’s time to remove or install the generator from the transmission for testing,
repairs or replacement, always use the generator installation/removal tool, NSN 5180-01-
508-5887, to avoid damaging the generator shaft, bearings or the spline adapter.
The generator is very heavy.
Trying to muscle it out without
the tool is not as easy you think.
It takes two to do the job.
The generator should not be
removed or installed without
the tool. Even if you somehow
remove it yourself, it has to be
supported and your strength
alone is not enough.
Removing and then carefully pulling the 53-lb
generator away from the transmission without the
kit puts undue pressure on the generator shaft and
bearings no matter how careful you are.
Without the kit attached to the generator, you
could bend or warp the shaft, damaging the generator
seal and housing and the inner components of the
transmission. If this happens, it throws the generator
and transmission out of tolerance, causing premature
failure of the generator. Then you have to replace the
generator spline adapter.
The best way to remove a generator is the safe way,
like it says in WP 1096 00 and 1097 00 of TM 1-1520-
238-13&P for the A model. For the D model check out
TM 1-1520-Longbow/Apache.
OH-58D…
The Slippery Skid
AH-64A/D…
It’s
Heavier
Than
You
Think!
slips and falls are
not uncommon when
working on your kiowa
warrior aircraft.
hey, you
didn’t slip
this time.
some
time
later…
you
got
that
right!
a little non-
slip material on
the cross tube
saved me a lot
of head aches!
oh no!
and
preventing
slips and falls
is a matter of
safety.
Apply
non-slip
material
to cross
tube
Use tool to remove generator
Removing generator without
tool damages shaft, bearings
or spline adapter
time to
tackle the
generator.
yeah…
we got
this!
excuse me,
no, you
don’t.
you better
get the
removal
tool
first.

ha
ha!
