echanics, a manufacturing defect could lead to snapped locking pin clips on
your M88A2’s tow bar. That’s not the best of situations if you’re trying to tow a
disabled vehicle.
The clips, NSNs 5315-01-439-4165 and 5315-01-436-9974, are used to secure the
headless pins at the clevis and lunette ends of the tow bar. Bad clips will snap under
stress at the circular portion of the clip’s head.
All bad clips have been purged from the Army supply system, but an unknown
amount are still in use on felded vehicles. So inspect the clips on your M88A2
like this:
1.
Remove all locking pin
clips from the tow bar pins
and eyeball them for cracks
or breaks. You can assume
that any missing clips fell out
because they were broken.
2.
Reinsert any undamaged
clips back into the tow bar
pins.
3.
Recheck
each
clip
for
cracks or breaks.
Undamaged clips are good-
to-go. Replace any that are
missing or cracked.

ot a round stuck in the chamber of your M777A2 howitzer, crewmen? If you can’t
remove it yourselF, you need to call explosive ordnance disposal (EOD) to do the job.
But your responsibility doesn’t end with that phone call. Because of the howitzer’s
design and EOD procedures, the ejected round can hit and cause major damage to the
howitzer’s saddle area.
So beFore EOD arrives, make sure the howitzer’s prepared. Use sandbags or other
dunnage to pad the saddle area behind and beneath the open breech. You’ll fnd this
reminder in the Caution at the bottom oF Page 2-199 oF TM 9-1025-215-10 (May
