et too close to the cooling fan blades on
your howitzer or ammo carrier and they’ll
make finger food out of your hands.
That’s why fan blade screens should
always
be used during maintenance on a
running engine.
The screens, NSN 2510-01-247-2976,
keep fingers, hands and anything else
from being pulled into the blades as you
check for leaky hoses, pipes and fittings.
Each screen has hooks and a thumb-
screw and locknut to secure it to the fan
shroud. The screens should only be used
during scheduled maintenance, though.
Remove them before regular vehicle
operation or the engine will overheat.
As a reminder to use the screens, put a
warning decal, NSN 7690-01-244-9849,
on both fan tower shrouds. You’ll need
general purpose cleaner, NSN 7930-00-
515-2477, to clean the shrouds before
applying the decals.

he bolt connecting the two
engine mounting brackets, NSN
2510-00-570-9715 and NSN 2920-
00-226-1984, together on your
ammo carrier is a bit too long for its
own good.
When installed as shown in Fig 2
of TM 9-2350-293-24P, the end of
the bolt sticks up enough to rub
against the starter housing.
Stop the rub by adding two extra
washers, NSN 5310-00-809-8540,
between the head of the bolt and
the bottom of the resilient mount,
NSN 5342-00-080-3496. Three
washers take up the extra length
and protect the starter housing.

it’s time to
get started on
some engine
