Dear Editor,
The lockwire used to help remove the Black Hawk’s input module seal can
easily break.
So, instead of busting our knuckles trying to pull that seal off with wire,
we switched to a light cable.
We save knuckles and time using

boy,
that was
easy
!
liding a tail rotor blade boot down a Black Hawk tail rotor blade can be a
tough job. You can make it easier with the simple tool shown on Page H-327 of
TM 1-1520-237-23-11 and by following the procedures in Para 5-4-42.1.3.
To make the tool, you need a 19-in piece of
3
/
8
-in rolled steel bar. Measure
four inches from each end and bend the rod 90
o
.
To install the boot, just slip the rubber boot over the ends of the tool. Slide the
tail rotor boot down the blade to its
position and remove the tool.
Input Module Seal Removal
rubber band is all you need to stop oil
spills in the Black Hawk’s tail rotor and in-
termediate gear box area during oil sampling.
Too often, when sticking the sampling tube
into the oil release valve, oil spills in those
areas.
To stop the spills, wrap a rubber band
around the sampling tube about
1
/
2
-inch from
the end. The rubber band should be wrapped
so it sticks up about
1
/
8
inch from the tube.
That should be enough to seal the release
valve and prevent spills.
Another solution is a
