Loader’s Tray Losing
Its Appeal
C
rewmen, trying to do your mechanic’s job will sometimes get you into trouble and
your vehicle damaged. You don’t have to look any farther than the Stryker’s height
management system (HMS) to learn that valuable lesson.
When the HMS isn’t working properly, some of you have watched while a
mechanic calibrated the system through the J2 connector on the air transport box
assembly.
That doesn’t look so hard,
you think to yourself.
Then, the next time your
vehicle won’t level using the
HMS controls, you grab a
paperclip or something similar
and try to calibrate the HMS
yourself. Big mistake!
Mechanics have a special
tool and the know-how that’s
needed to calibrate the HMS.
And if there’s something else
wrong, they can troubleshoot
the system to Fx the problem.
Using your own homemade tool will just damage the system. And even worse,
some crewmen will forget to remove the paperclip afterward. That leaves the J2
connector open and the system stuck in the calibration mode!
Bottom line:
If your Stryker is sagging and you can’t level it using the HMS
controls, don’t try to Fx it yourself. Call your mechanic!
If your loader’s tray is peeling, you’ve probably
got a “3rd generation” tray, NSN 1015-01-537-0697
(PN 13010524). Those trays had a Te±on
®
coating
added for extra protection, but they haven’t lived up
to expectations.
So if your tray is peeling, stop using it now! The
peeled coating can get lodged in the chamber or
breech and cause problems with Fring the main gun.
Get the tray replaced with a new “4th generation”
tray,
NSN
(PN
13010524-
1). The Te±on
®
coating on these trays has been
replaced with a dry Flm lube phosphate coating that
won’t peel.
The new tray will appear in an upcoming revision to the M1A1 and M1A2 SEP
parts manuals. Until then, grab your stubby pencils and add the new NSN as Item 73
in ²ig 101 of TM 9-2350-264-24P-2 and Item 72 in ²ig 64 of TM 9-2350-388-24P-2.

HMS Calibration Is
Not
Your Job!

I know just what
you’re thinking, but
calibrating the

is a mechanic’s job,
not
an Operator’s.
