Dear Half-Mast,
I’m trying to find an NSN for
the M88A1 recovery vehicle’s
ground hop kit. Seems I
remember being able to order
this a few years ago.
Also, I’m having trouble
finding the transmission caps
to use when ground-hopping.
Can you help me out?
SFC F.J.M.
Dear Sergeant F.J.M.,
You bet! At one time there was a single NSN for the ground hop kit. Unfortunately,
it was discontinued. Now you have to order the kit by its individual components:
You’ll ±nd these components listed in WP 0488 00-32 of TM 9-2350-256-20-2
(Jun 05).
The transmission caps are a little tougher to ±nd. They’re in TM 9-2520-215-
34P,
Cross-drive Transmission Assembly.
You’ll ±nd them listed as Item 2 in Fig
36 of WP 0038 00-2. A set of caps plus the storage case come with NSN 2590-00-
330-8642.
C
rewmen, the integrated sight unit (ISU) on your Bradley has elevation and azimuth
knobs to adjust the gun reticle up and down and left and right. Couldn’t be simpler, huh?
Not so fast. Though the knobs look pretty much the same, they work a little differently.
The elevation knob works by
simply turning it. But to adjust the
azimuth,
you have to first push
in the knob
and then turn it. Look
carefully and you’ll notice there’s
even a small PUSH label right
beside the AZ under the knob.
Problem is, some crewmen are
forgetting this extra step for the
azimuth knob. They try forcing
the knob without pushing it in
and it snaps.
So remember: It’s turn for elevation and push and turn for azimuth.
AZ knob must be pushed in before turning

Push the AZ Knob First!
Well, that takes
care of the
repairs.
Are we gonna
ground hop this
engine before
reinstalling it?
That
would save a
lot of
time
if there’s
still a problem…
…But we
don’t
have
a ground
hop kit!
there’s
only
one
thing
to
do!
Here’s an email
from a mechanic
wth an M88A1
ground-hopping
kit question.
That’s
right up
my alley!
I’ll
take it.
