New M40/M42 Hood
The one-piece hood for the M40- and M42-
series masks is being phased out. When
an old hood needs replacing, order the
quick-doff hood, NSN 4240-01-376-3152,
and a universal second skin. The skin
comes in two sizes: small, NSN 4240-01-
413-1540, and medium/large, NSN 4240-01-
413-1543. Instructions for using the new
hood are in the -10 manuals for the M40
and M42 masks. The new hood lets soldiers
be deconned without taking off their masks.

Black Hawk Gasket Purged
Use NSN 5330-01-414-9436 to get the starter
gasket for your Black Hawk’s auxiliary
power unit. The old one, NSN 5330-00-237-
5653, is being purged from the system
because it’s made of asbestos. The gasket
is Item 4 in Fig 138 of TM 1-1520-237-23P-
4.
M88A1 Heat Diversion
Page 20 of PS 551 rightly said that tilting
the oil reservoir access plate will deflect
hot air from the personnel heater. That
sends the heat under the floor plates and
keeps the whole vehicle warm. Just make
sure you move the portable fire
extinguisher near the right side air
particulate filter first. If the extinguisher
gets too hot, it could discharge.
Compressor Filter
NSN 2940-01-186-0592 gets the oil filter
element and packing for the 250-CFM
compressor shown in Fig 74 of TM 5-4310-
452-24P. The gasket is available separately
AN/PVS-7 Lens Cap
The protective cap for the lens on all
models of AN/PVS-7 night vision goggles
was left out of the TMs. Get the cap you
need with NSN 5585-01-397-6608.
