Don’t force the feeder
handle down.
The result
of muscling the feeder
handle down into the
locked position is a ruined
14-pin connector. Once
you lock the drive shaft
handle in place, the feeder
handle should lock in place
easily by using steady
pressure with your thumbs.
If it doesn’t, call for your
repairman. Something
is wrong.
Dear Half-Mast,
I need your help settling an argument. Whenever we have to open the hull
power distribution unit (HPDU) on an M1A2 SEP tank for maintenance, I
think we should replace the cover gasket, NSN 5330-01-355-6398.
Some of the other mechanics in my unit say as long as the gasket isn’t
damaged, it’s OK to reuse it.
The HPDU is very expensive to replace, so it seems to me that a $25
investment for a new gasket is worth the money. What do you say?
SSG M.S.H.
Dear Sergeant M.S.H.,
I say you hit the nail on the head!
My contacts at TACOM tell me that a
lot of these HPDUs have been failing
because of leaky gaskets. And that’s
usually due to a mechanic reusing
the seal instead of replacing it.
Remember, water and electronics
don’t mix. That gasket needs to
be replaced any time the seal is
disturbed or the HPDU is opened.
You’ll Fnd the gasket replacement
procedure in WP 0122 in
TM 9-2350-388-40-1 (±eb 09).
Now get out there and
spread the news!
